    Extreme values for all months are highlighted in bold (June 1949 driest, August 2011 wettest).

    Tied values are in italics in each month and for the annual values. 

    Years are to be read with the values above them (e.g. Dec 1973 had 9.98", Dec 1936 had 7.53") etc. 

    __________________________________________________________________________________________

    2021 precip totals will be incorporated at end of year .... they appear below the monthly

    columns for now with ranks attained.

    U.S. precipitation records and snowfall records are not tabulated in the same format as 

    Canadian precipitation (with rain and snow amounts separated), so the only other table

    I can provide is for snowfall rankings. There were only traces in May, so the months that

    require ranking are Jan to Apr and Oct to Dec. Quite a few months have zero snowfall, those

    are listed at the top of the table in chronological order.

     

    <<< Snowfall rankings by months, years and winter seasons >>>

    Note: rank on left of table is from 1st (lowest snowfalls) to 152nd highest ... rank on right

    is the reverse, running from 152 at top to 1 at bottom for most snowfall. 

    Tied values are in italics, except for multiple ties of 0.0 or Trace in Mar, Apr, Oct, Nov, Dec.

    Trace totals are listed after zero totals, but trace = 0.0 for calculations.

    Here's a brief summary of the annual results for 2020 at both locations. 

    At Toronto, it was the 6th warmest year (of 181) at 10.45 C behind 1998, 2012, 2016, 2001, and 1999. Corrected for urban heat island, it remained behind those five and also 1921 and 1931, to move to 8th warmest.  July 2020 was the second warmest on record but accomplished that mostly on the strength of persistent warm overnight lows, even so none of them set a daily record. The year's highest temperature of 96 F (35.5 C) on July 2 is quite close to the long-term average for that statistic. It was not a particularly wet or dry year and the only real highlight was a heavy rainfall in January that was the heaviest since 1843 in that month. Despite a lot of warm weather in the year, a record cold spell in early May managed to set a new overnight low daily record (beating one set in 1850), the first time that has happened in May since 1923 (due in part to the ever increasing urban effect as well as climate change factors). This cold spell was probably the only part of 2020 significantly below even the inflated recent normals. A daily record high was set later in the same month (two more occurred in November). 

    For NYC it was a fairly similar story, in fact it appears that the year will tie 2012 as warmest on record, awaiting confirmation on that as my source has not updated December 2020 (although all the other months in the source match the values I derived from instantly available CF6 reports). To a second decimal I calculate that 2020 may be .01 lower than 2012 but both round to 14.1 C and also to 57.3 F. Will edit this if it proves inaccurate in the official linked publication (see table of monthly NYC temps). For the urban-adjusted series, 2012 and 2020 drop to tied 3rd with 1949 and 1953 using advantages of 0.3 and 0.2 to move past them (barely). It was not quite as hot relatively in July (7th warmest) and the annual max there was also 96 F, a somewhat lower than average value long-term, but November edged past 2015 as warmest (Toronto's rank t5th with 1975 the warmest November). In fact November was the only reason that 2020 can be compared to 2012 for NYC, without it the year averaged about a degree lower. 2012 had a record warm March. Also NYC had a fairly average precipitation year in 2020 without big events, a 10.5" snowstorm in mid-December prevented the year from being the least snowy calendar year but winter 2019-20 was one of the least snowy winter seasons (4.8" was third lowest behind 2001-02 and 1972-73). Toronto had a more normal snowfall near the long-term median in that winter but close examination shows that much of it was probably melting within hours of falling so that snow depths were likely well below average. 

    Although the years are shuffled around a bit, the Toronto and New York recent temperature trends look very similar to the CET and some of the contenders from the past are the same years (1921 and 1949 were also quite warm years in Britain). 

    One thing my research has shown me (that needs further work) is that there's probably a non-random second order cause and effect mechanism pushing temperature trends on both sides of the Atlantic, apart from the phenomenon of recent warming. I have found quite a few instances of very similar trends in past years, but at the same time, it's not a 1:1 locked in relationship. The very hot summer of 1936 for example had no parallel in the CET records. But quite a few other top 20 summers from before 1980 are similar, 1868 and 1911 were both very hot summers in North America too. Whether this is some function of atmospheric wavelength, or solar forcing, or a combination with other factors in play, remains a subject for further research. 

    Besides that, I seem to have finished all the tables I wanted to work on, looking at my excel files to see if they can be shared with readers, which I hope to do within a few days.

    I have the NYC data base ready to share, but the link to official NYC temps still has not updated for Dec 2020 or annual 2020, and in my quality control I found two possible errors in that data base which I have forwarded through my New York City contact Don Sutherland who agreed with me that they appeared to be errors. Before 1920 the data base and the official numbers have larger variations which are evidently the product of data management so I have put in a request to find out if there are published revisions of the data, or if this was just done using formulae which apparently are partly based on a number of different factors (climatological day, exposure, wet or dry months, may be some of these factors). In general the revised numbers average out the same as the data base numbers over decades, as the changes are in both directions to the monthly averages. These will be tabulated in the data base. There is always the possibility that some of the revisions are also clerical errors of the same kinds as noted ... the two data points being questioned are May 2005 (58.9 instead of 59.8 as shown, this one looks like a clerical error) and Dec 2017 (35.0 instead of 33.4, the 35.0 supported by the published CF6 table in the NWS data base). No obvious cause for that second discrepancy (and it may turn out to be a quality control decision that would maintain the 33.4 figure). 

    Meanwhile, I have noted the Jan 2021 monthly temperature and precip/snow data in the tables. In general all 2021 data will be found at the base of the tables until the year is complete, then the tables will be edited.

    A new daily record snowfall occurred on Feb 1, 2021 when 14.8" fell at NYC, breaking the record from 1934 of 9.8" -- this also led to a new two-day record for Jan 31-Feb 1 (noted Feb 1 in the tables) of 16.8" ... this is the second 10" snowstorm of the winter season. As of the 12th, February had already moved past all but thirteen other Februaries for total snowfall which is now 21.2" equal to 14th (1996).

    No new daily records were set in Jan 2021 at either Toronto or New York City.

    That is mainly true of the summer extremes which as my tables show had peak readings in 1936 for July and 1918 for August. Some of the heat waves of those years were balanced by intervals of cool, dry weather so that the months were not the extreme values (although 1921, a rather average July for NYC, was and remains warmest on record for Toronto). The tables that I encourage people to use for monthly comparisons are the urban-heat-island adjusted tables since these will give the earlier readings the more appropriate placements. For example at Toronto July 1868 ranks several spots higher as it had no assist from an urban heat island. Another peak in temperatures in the 1930s was the run of mild Januaries, especially 1932 and 1933. 

    The 1950s did well for warm spring months and the 1960s to 1971 for warm autumn outcomes. September 1881 was a notably warm month especially when urban heat island is factored in.

    The main change in the climate in this region seems to be a gradual lessening of the frequency of coldest 10-20 percentile type weather, it hasn't disappeared altogether but it shows up less frequently and that is not just because of an urban heat island, the same is true for entirely rural locations in the northeast U.S. and southern Ontario. The climate is also cloudier now than it used to be, the years 1962 to 1966 were probably a peak for sunshine as shown by data that was available for Toronto until recently (not yet incorporated into this thread because I can't find the sources, however, I recall seeing them about 30 years ago and there had definitely been a trend down from the 1960s to the 1980s, after a trend up from the 1880s to 1930s, slight relapse to the 1960s, so the 1930s and 1960s produced some of the higher sunshine totals). 

    The east coast weather "weenies" generally believe that snowfall in their region has decreased in frequency but increased in amounts per event when there are snowfalls. I don't think that's the trend for Toronto or the Great Lakes in general; there, I think the snowfall frequencies and average amounts per fall are both in decline recently, although (outside lake effect snowfall zones) the winter climate has always been a case of extremes, in all decades you can find mild almost snow-free winters and colder very snowy winters. The balance has shifted towards more mild and less cold, but the extremes remain in play as seen by the rankings of Jan 1994 and Feb 2015 as well as Dec 1989 (all top five cold months).

    I can finally confirm that NYC (Central Park) tied the record in 2020 for warmest year (57.3 F, 14.06 C) set in 2012. With the warmest November on record, the year was in position to move into top spot but December was only a moderately mild month. The delay in confirmation ended on the 7th when the official website for NYC updated their monthly averages (see link in Table 1 of NYC data on page 2 of this thread for further details and that link). 

    This development means that I can post the link to my excel file since the data in that have been confirmed by this update. The plan would be to post updates of the excel file every three months after various meteorological seasons have ended, so that users can have the latest data without needing to update their own files to get it. I will post sources for these updates in case you want to update more frequently. 

    I have just edited in the link to the NYC data file. Navigation aids are posted in the section between columns GD and GR rows 1-21.

    The Toronto file needs a bit more work and will be made available within a week of the NYC file, so by 19th March. 

    Meanwhile, the winter season of 2020-21 is in the books, and all tables are updated to show where the season and the three months ranked. Generally speaking, February 2021 was closer to average than the other two months which were milder. This left the season (winter 2020-21) in the top third for temperatures but not record territory. Toronto had near average snowfall amounts while NYC ran above normal with both Dec and Feb well above normal (Feb ranks 8th snowiest out of 153). The rainfall components were less prolific at both locations and for Toronto in particular the winter ranks among the driest recent or long-term, although not quite into the top ten of dry winters. Snow cover was intermittent and my Toronto contacts tell me that the winter seemed fairly bland and easy for getting around while not seeming overly mild by recent standards. 

    This NYC data file will be updated regularly and the updates posted about a week after each meteorological season ends with the three new months of data included, so if you're interested in this data set, you won't need to update your own copy, just replace it with the updated version every three months.

    The Toronto data base on excel file is finally ready for sharing. The site navigation is in the range IP1 to IU63, and there's a reminder of that address in cell A1 (where otherwise not enough room for all this info without risky large-scale file manipulations). So if you do go into this file, be aware that there's a site navigation section that will definitely cut down on your orientation time if you read it first, and the address is at cell A1 where the file should open up.

    There are features in this file that are not yet in the thread, such as warmest and coldest weeks, wettest weeks, and comparisons of Toronto, CET and NYC annual means. There is also a table of extremes for mean daily temperature (the thread only has extremes of max and min so far). 

    So I will now attempt to attach this file which is probably 2-3 times the size of the NYC file already available (previous post). 

    (think it should be okay)

    This graph shows the three data sets in 11-yr r.m. format (NYC green, CET red, TOR blue) after the NYC and TOR data are gradually reduced by up to 1.1 C after 1981 to eliminate the urban heat island component of warming. This leaves the three data sets comparable and generally speaking they seem to be running along in lock step with a few minor variations. The warming around the 1890s is a bit more prominent for the North American locations which were recovering from a very cool period in the mid-19th century, whereas the CET shows a somewhat less pronounced increase that appears to start a bit later perhaps (more like mid 1890s). The warm period around 1948-55 is evident before either slight cooling or flat temperature profiles in advance of the late 1980s warming that seems to have more momentum at NYC than in the other two sets which level off somewhat near the end (and the end in this format is the past decade or 2010-2020 inclusive). No 2021 data went into this analysis. 

    This graph is part of a much smaller excel file I created to show only the mean annual temps at the three locations.

    Anyone who downloaded the Toronto file should go in and correct one cell, I was working on the area of rankings for UHI corrections just before posting and updated them for Jan 2021, which involved adding one to ranks higher than its rank. In that process, a number slipped (probably one of those instances where the computer freezes up and you think you just corrected cell A but the result ends up in cell B). So what we have to correct is cell HE1969 (Jan 2015), which shows as 3 (at least on my home version it did, maybe the change happened after I uploaded). If you see a 3 there, it needs to be changed to 136 and that will trigger one other cell change for an average of 2015 rankings.

    I went back through the chain and all other entries for Jan 2015 are unaffected. The rank in the raw data table is okay and the actual temps listed in all tables are correct. So that was the only place this error impacted and as there had been no graphics done for that table, nothing to note there.

    What I'm doing recently is to construct the same colour-coded display for the UHI corrected ranks as already exists for the raw data ranks. Then since some of those change (early ones show some increases, late ones some decreases) I outline the changed colour code cells to give an overview of how the urban heat island correction affects the look of the overall data. It certainly flattens out the initial "sharp increase" look without totally removing the overall increase.

    Anyone who has the file but finds the change more work than necessary can wait for the next seasonal update where this error will be corrected and the new graphic as mentioned will be available.

    I have a few quality control panels to try to avoid data contamination problems, as you'll know if you work on excel files, the odd time you can type some intended change in and not see it where you thought it should be, which means perhaps it fell into a cell you had been looking at earlier. That would contaminate your data. But with the quality control panels, I can check at regular intervals that nothing like that has happened. The ranking tables are going to be placed in a newly designed q.c. check system where out of place ranks will show up on a graphic display. Given that there's probably over a million data points in the file, the odd error is probably difficult to avoid, even the pros have errors in their files as we found out with the NYC data.

    That "3" cell must have shown up in the edit because the original work was done from tables with accurate ranking for Jan 2015 and I would have been typing numbers like 136 at that point, suspect that it was during a computer slowdown during the 2021 rank insertion updates. Have checked to see if any other obvious errors in the table, the new q.c. system should ensure that there are no significant errors (a lot of ties using the C data, and some random scatter of different ranks from the older F numbers although the higher and lower ranks tend to be immune to scrambling as they are separated out more).

    Speaking of NYC, if you downloaded that file, a very minor change can be made, the record high on 25 Jan (60, 1967) was not colour coded (red). The day before was also a record, so if you can't see how to achieve the colour code but want to make the change, just copy the cell for the 24th (68 with red highlight) down one cell, then change the number you see to 60. That minor error is located in cell DA25.

    There are some interesting month to month or season to season variations in the overall trends. One was that in the "climate warming" episode around the 1890s, June was off to a faster start than July or August in that warming. Another was that the more recent warming shows the opposite trend, July remaining closer to average than faster-warming June and August. The winters in the 1840s tended to be considerably milder in terms of rankings than the other three seasons, in fact after the UHI corrections the winters ended up looking fairly similar to the mid-20th century before the "modern warming" spike. Some of those observations are illustrated by graphs in the edited version that will be available after May ends.

    Daily record maxima now and in past intervals for NYC

    This section will be a log of record daily high temps for NYC, both in the overall data set 1869-2021, and from the perspective of each year at its conclusion.

    This analysis may give some background for determining how changes are actually comparable to, or different from, past experiences. 

    I start with the interval 1869-1900 (inclusive) and determine a "starter record" for that 32 year interval. This would have been the record high going into the year 1901. Then for each year, I adjust the list and show the records that existed at the end of each year. The expected number of records will drop gradually going forward. During the starter interval, it is a constant 11.4 (leap years 11.43, regular years 11.41). Then with each passing year, you would expect at random in a steady-state climate that the numbers would gradually fall off because it gets a bit more difficult each year to surpass records as they increase (which is by definition what they have to do). The count is adjusted for ties, so when a year ties a previous year, its count for that date is 0.5. If it's a third tie then the count is 0.33, and in the few four-way ties that exist, 0.25. (No five-way ties were detected). NYC temps are recorded to nearest whole Fahr degree, so no decimals come into play. I have done this same analysis for Toronto (in the excel file, not in this thread) using 1840-70 as the starter record interval, and the analysis looks quite similar, but it's a bit more complicated by the fact that potential records after 1977 are in tenths of a degree Celsius whereas the record to 1977 was like NYC, whole Fahr degrees. That created a few "pseudo-ties" which were only ties when the Celsius value was converted to a whole Fahr number (but this affected only about a half dozen cases, the rest were more clear cut). 

    Four years in the entire NYC record failed to set a new daily record, those being 1958, 1992, 2004 and 2014. Quite a few others set records that have since been broken in all cases, most of the earlier years have had their record harvest culled considerably but a few survive. The ratio of surviving records to the original records (at end of year) is a percentage that I call "survival ratio." This tends to increase towards nearly 100% in the last thirty years although some records set as recently as 2017 have already fallen. Another interesting parameter to track is the longest surviving record for years that have now lost all of their original set. 

    In this analysis, any starter record ties within the interval 1869-1900 are adjusted as explained in the count, and if a starter record survives as a tie then the survival count is adjusted. That is also true for later records except that once we pass 1901, the adjustments occur right away as ties are created, but not retroactively, so let's say 1901 ties 1966 (as happened in a July heat wave) then 1901 gets 1.0 in its "original record" count and 1966 gets 0.5 at that point, but both get 0.5 in the survival totals. 

    Two days of the year had four-way ties for the eventual records, both in late July (28th, 30th) and eight cases of three-way ties are noted, 48 others are now two-way ties. That leaves 308 days of the year with a single exclusive record high. 

    This is a table of the count of surviving record highs as of March 2021 (when one new record was set replacing one from 1922). The decade totals are for ten years that can be referred to as "the forties, the fifties" etc, e.g. 1940-49 rather than the more familiar 1941-50. I do show the more traditional decade counts beside this table's results. The main finding here is that the 1940s had a similar rate to recent warmer decades, with the 1960s and 1970s somewhat lower. The count of surviving records is now sparse before 1910 and picks up considerably thereafter. It should be noted that in a "steady state" climate one would expect these numbers to vary around a fixed mean of 2.4 per year (there is no reason to expect a trend in any direction) so actual trends presumably tell us information about the changing climate. I am generally leaving out the reasons for this as I want these NYC and Toronto data sets to be available for anyone to make their own analysis without me setting any expectations or biases. But I think this analysis is valuable because up until now I had not seen anything very similar to what follows, the log of the gradually changing totals as seen from earlier points in time. 

    (36.41 records from the starter period 1869-1900 survive, this being the result of 31 exclusive records maintained, nine shared (4.5), two three-way ties (0.67) and one four-way tie (0.25). This interval should have kept closer to double that number at random. The only years in the starter period to have done relatively well at maintaining records are 1880, 1881 and 1895.)

    Now for comparison, the count of record highs at the end of each year, before most of them were broken later.

    For 1869-1900, ties are within that 32-year cohort. There were probably a few cases where one near-record was 

    broken by another so that people living in that year might have noted a few additional records. The count from 1901

    to present time is the adjusted count (e.g., a tied record in 1901 tying previous years counts 0.5, a tied record later in

    the set counts 1.0). 

    <<< ORIGINALLY SET DAILY RECORD MAXIMUM COUNT for NYC (starter period 1869-1900) >>>

    In this compilation, the expected numbers at random are 11.4 per year to 1900 and then slowly decline

    to 2.4 at end of the set. Instead of the second decade total, an expected total is given, with that compared

    to the actual total as a surplus or deficit from the expected numbers at random. It should be inferred that

    "expectation" here applies to the period elapsed to the years in question, and for 1869-1900 it is structured

    to be random over that interval, so the only variability explored to 1900 is the decade by decade outcomes.

    The analysis shows that every decade has done at least somewhat better than random expectation at setting new records, because the starter set (1869-1900) was relatively weak. 

    In some future posts I will examine what happened to various years' records over time and try to establish some rules for survival rates. For example, 1913 set 25.83 new records, a result of 25 exclusive records and one two-way tie and one three-way tie with earlier records.

    Of these, only one has survived as part of a three-way tie (94 on Aug 18 tied later in 1987 and 2002). So the count for 1913 has gradually decreased from 25.83 after 1913, to 21.33 by end of 1920, 10.83 by end of 1930, 9.33 by end of 1940, 7.83 by end of 1950, 5.33 by end of 1980 and is now just 0.33 (a survival rate of 1.3%). This is probably the most feasted upon year, and some of its records would have held on nearby dates, for example, 89 and 89 May 2-3 lasted until 2001 and are above surviving records for May 1st and May 14th. What 1913 illustrates mainly is that a warmer year shortly after the cooler interval of starter records found the menu relatively easy pickings, many of these 1913 records were set in the first five months of winter and early spring weather, and a few in November. But as the warming became more established, later years were able to do slightly better than 1913. 

    The fate of the eventually broken 26 daily records or shares can be seen in this table: 

    1913 Records survived until these years

    1916 (2) 1917, t1918,22 (br 1930), 1919, 1921 (3) (one had tied 1903 for count of 0.5), 1922 (2), t1923* (br1926), 1924, t1927 (br1931), 1929,

    1930 (2), 1934, t1939 (br1988), t1945,71 (br1983), 1950, 1963, t1973 (br 1990) and another broken in 1973, 2001 (2) and 2006 (Jan 21 60F). 

    *was a three-way tie with 1873,79.

    ______________________________________________________

    The fact that 1913 lost some of its records within the same decade shows that there would be an inherent bias towards a surplus of records in any given decade, since each time that happened the total count would be 2 rather than 1. However, records broken within that short a space are not a common occurrence. The combination of a weak starting field from the starter records, and this bias of double counting, is probably weighted about 2:1 towards the weak start. 

    If the climate continues to warm, there will likely be ongoing surplus numbers of records. 

    In recent decades (starting 1970) only these years have underperformed in terms of setting new records relative to what would be expected in a random sequence: 

    1981, 1992, 1994, 2003, 2004, 2009, 2013, 2014, 2015, 2019. 

    Some of these have only been marginally below expectation. 

    Nowadays a "normal" pace of setting new records would be around two exclusive and one tie. 

    In some future posts I will examine some of these statistics and track what happened to a few other prominent past years. Some of the starter years lost most of their records within 30-40 years of the end of the starter interval. 

    No year before 1981 has retained all its original records, 1981 only set two in Feb and Apr and has held on to them. The following year 1982 has already been reduced from a count of 3.5 to 1.0 (two records are now tied with other years -- all of its records were set in December, so the interval from April 3, 1981 to Dec 4, 1982 set no records). 

    The first year in the sequence to hold on to 80% of its established records was 1953 which has retained 8 of its original 9.5 count. Then 1956 only set four but three are still unbroken for 75%. An early outlier is 1925 which has held on to 4 of the 6.5 count it had at end of the year, all of those coming in a June 2-5 heat wave. 

    Besides the four years which never set a record, the year which was least able to hold records was 1978 which established one record (67 on Dec 4) that lasted only four years to 72 in 1982 (and that was broken in 1998). 1968 established only two, one on April 13 which lasted to 1977, and one on Nov 29 that was broken in 1990. 

    The years which were most recently removed from record holding were 1889 (64 on Dec 25 was tied in 1982 then broken in 2015 by 66F), and 1872 which was in a three-way tie with 1916 and 1919 (93F) for Sept 8 up until 2015 with a new record of 97F. But the year which held on longest to an exclusive untied record before being eliminated from record holding appears to be 1896 (lost 91F on May 11 to 1993 92F). (Other years have lost more recently but still hold some records, for example 1922 which recently lost March 26 to 2021).

    The now broken records most unlucky to be removed would probably be 89, 88 on April 7-8 of 1929. These fell to 92, 90 (2010, 1991) but would still be records on every day but two in the next eight days and even in all four days between April 21 and 24 as well as May 1st. 

    This graph tracks the statistics of annual records set, sustained to end of the data, random expectation and survival percentage of records set. 

    The grey ascending component is survival rate in %. The blue gradually diminishing statistic is number of records set each year. This compares directly to the orange-yellow line that starts out at 11.4 and begins to head down to 2.4 at end of the data, which is the random expectation (in a steady state climate) of annual records set by end of each year (1869-1900 are a starter period with equal chances at random). And the bottom running orange statistic is the annual number of retained daily maximum records (adjusted count for ties, which has its maximum values as follows (in chronological order) ...

    Continuing the deep dive into record NYC temps, I plan to examine each 30-year interval (starting with the 1869-1900 starter period) and log the records set in each year. This will give anyone interested in more detailed research or comparisons with UK-Ireland climate some interesting contextual data. 

    For each year, I will mention the numbers of temperature records (including the other types) and the eventual disposition of those records later in the series. 

    Note: the term "benchmark" is sometimes used -- a benchmark record is not only a daily record but the earliest warm reading in the spring portion of the year, or latest warm reading in the autumn portion. They reverse around mid-January and mid-July. For cold records the concept is the opposite, latest cold reading in spring, earliest in autumn. Also identified where appropriate are monthly extreme values. 

    1869 -- 8 record highs (for 1869-1900) established. All were later broken. The average year of record breaking was 1923. One was tied (1937) before being broken (1955). The average deficit relative to eventual records was 9.1 deg. By end of data 1869 held seven record low maxima (two later tied, count 5.83). 

    1869 established five record lows, two of which are ties (count 4.0). There were no surviving high minima (not tracked like high maxima, in the brief heat wave of Aug 20-21 shown below, high min was 74, date record was 78 (1906). For Feb 13 the min was 40 (record high min is 47 from 1880).

    1870 -- 10 record highs (for 1869-1900) established. Three were ties before 1900 (another later) and another a three-way tie (count 7.83). All were later broken. The average year of record breaking was 1934. One was tied (1935) before being broken (1938). The average deficit relative to eventual records was 8.1 deg. By end of data 1870 held only two record low maxima (one later tied, count 1.50). 

    1870 established no surviving record lows, and has two surviving high minima (77 June 29, 82 July 17), neither has been tied since (76 and 79 closest).

    1871 -- 10 record highs (for 1869-1900) established. Two were ties by 1900 (another later) (count 9.00). All were later broken. The average year of record breaking was 1939. One was tied (1923) before being broken (1961). The average deficit relative to eventual records was 10.1 deg. By end of data 1871 held eight record low maxima (one later tied, and another part of a three-way tie including 1869 for July 1, count 6.83). 

    1871 established eight surviving record lows, three of which were later tied (count 6.50), and has one surviving high minimum (55F April 10, tied in 2013, count 0.50). A warmer night in a four-day warm spell as noted below for record highs, on April 9 (62F) survived until 1991 (68F) and remains well separated from third place 55F.

    1872 -- 15 record highs (for 1869-1900) established. One (June 12) was a tie by 1900 (with 1898, that one and five others were later tied) (count 14.50). All were later broken. The average year of record breaking was 1924. Six were tied (1898/1901, 02, 08, 16/19, 27/32, 1930) before being eventually broken. The average deficit relative to eventual records was 8.0 deg. Also notable were 88 and 89 F on May 9-10, broken in 1896 and for 10th also 1889 (so therefore not starter records).

    By end of data 1872 held seven record low maxima (one later part of a three-way tie, count 6.33). 10F on March 5th was a monthly record low maximum. There were three record low maxima Dec 24 to 27 with the 25th not quite joining in (13, 15, 12, 15; the 25th held to 1983, 13F). 

    1872 established seven surviving record lows, one of which was later tied (count 6.50), including 3F also on March 5th, lowest minimum for March, and the year has no surviving high minima, 78F on July 2 during a heat wave noted below was also broken by 1901 (82F).

    1873 -- Only 6 record highs were (for 1869-1900) established; third lowest count 4.25 in the starter period to 1893 (3.00) and 1875 (3.25). One record high was a four-way-tie by 1900 , and two others were ties within the starter period so the count was 4.25 for the starter record era; one of those two was later tied in 1944 to become a three-way tie and the other tied in 1913 and 1923 to become a four-way tie at that point (to 1926). Another record was tied in 1973. All these 1873 records were eventually broken. The average year of record breaking was 1940. The ties within the interval and in 1973 would change that stat to 1909 in terms of the average year tied or broken. The average deficit relative to eventual records was 7.0 deg. By end of data 1873 held 14 record low maxima (three tied, count 12.50). The most significant of them is probably 29F on Nov 14, an early season benchmark. 

    1873 established seven surviving record lows, one of which was later tied twice (count 6.33), including -1F on Feb 24 which is the latest subzero reading in the winter season to date, and the year has no surviving high minima (46F on Dec 4 survived to 1940).

    1874 -- Eleven record highs were (for 1869-1900) established; two were ties so the count is 10.00. Two have survived as eventual record highs. That makes the surivival rate 20.0% (as seen from 1900 after the eventual ties). The average year of record breaking for the ten that did not survive was 1926. If the survivors fell next year that would change to 1942.  The average deficit relative to eventual records (including the two records) was 8.3 deg but would be 10.1 for the nine that have been beaten. By end of data 1874 held seven record low maxima (two tied, count 6.00). The most significant of them is 38F on April 29th, a late season benchmark (no date later in the spring had a max lower than 43F). 

    1874 established eleven surviving record lows, two of which were later tied (count 10.00), including five near 32F between April 27 and May 3. The year has no surviving high minima and even during two notable warm spells in the winter did not set any particularly impressive high minima.

    1875 -- Only five record highs were (for 1869-1900) established; one was a two-way tie and another a four-way tie so the count is 3.75, lower than each starter year and most later years also, except 1893 (3.0) and some much later into the record with lower expected frequencies. This is not surprising as 1875 was the coldest year on record. The only warm part of the year was the second half of December. None of these four have survived as eventual record highs. The average year of record breaking was 1945. The average deficit relative to eventual records was 12.0 deg. By end of data 1875 held 14 record low maxima (four tied with one other year and one with two others, count 11.33). The most notable spells were in April, with four between 13th and 19th, the 17th-18th 33F and 32F are colder than any later low maxima in any other years by 4 deg, and also Nov 30 with 14F a lower max than any other November day by nine degrees. No day was colder in the interval Dec 1-17 (18th 1919 was 11 F). February 1875 was also generally very cold despite the one mild reading noted below, and provided two records.

    1875 established fifteen surviving record low minima, one of which was later tied (count 14.50), the most significant were three benchmarks (late season outliers) on April 19, 21 and 22 (22, 26, 28F all latest on record), and 5F on Nov 30th, the lowest November reading. Readings of +1F on Jan 18 and -1F on Jan 19th were taken out of the record column by 0F 1982 and -2F in 1994. The year has no surviving high minima.

    1876 -- For its time this was quite a warm year and there were 18 starter record high maxima (for 1869-1900) with 2 two-way ties, 2 three-way ties and one four-way tie, the count was 14.91. Of those, two have survived, both in January. Also, 66 on March 7th was broken by 68F in 1878. The average year of record breaking (for 16 cases) was 1921, if the two January records fell next year that would 1932. The average deficit relative to eventual records was 7.2 deg (8.1 for the records actually broken). By end of data 1876 held six record low maxima (one tied, count 5.50). December provided three of those.

    1876 also established six surviving record low minima, three in October and three more in December and with no later ties (count 6.00). The most significant was 32F on October 15th which is the earliest frost at the location. There are two surviving high minimum records, one later tied in 1943 (77F on June 28) and another still exclusive (79F July 13th). The count then is 1.50. The min on Jan 2 was 46F but the record of 49F was set in 1890, tied 1911. We have now examined eight years and so far only five days share record high mins, and the count is 4.0 (at random should be around 20 by this point).

    1877 -- There were just eight starter record high maxima (for 1869-1900) with 3 two-way ties, so the count is 6.50.  All have been broken. The average year of record breaking was 1919, and the average deficit relative to eventual records was 8.1 deg. By end of data 1877 held just three record low maxima (one tied, count 2.50). 

    1877 also established just one surviving record low minima (58F July 14), now tied by two other years (1888, 1926) for a count of 0.33. There were no surviving record high minima.

    1878 -- Despite this being quite a warm year for the era, only ten record highs were set (for 1869-1900) and with three 2 two-way ties and one three-way tie the count is 7.83.  All these records have been broken. The average year of record breaking was 1917, and the average deficit relative to eventual records was 10.4 deg. By end of data 1878 held five record low maxima (three tied, count 3.50). 

    1878 also established three surviving record low minima with no ties for a count of 3.00. There were no surviving record high minima, although several spells of quite warm nights for that era, for example, 47F March 3 (broken by 48F in 1991 and the eventual record of 49F in 2020) and 65F on Oct 17 (broken by 67F 1928).

    1879 -- This was a generally warm year and 20 record highs were set (for 1869-1900) and with three 2 two-way ties, one three-way tie and one four-way tie, the count was 17.08 (by 1900).  Two of these records have not been broken for a survival percentage of 11.7%. The average year of record breaking was 1930, but if the two surviving records were to fall later this year, the average year of record breaking would move to 1940. The average deficit relative to eventual records was 8.5 deg but for the eighteen that have been broken, the average is 9.5 deg. October 1879 was a very warm month, and several other days missed starter record status by 1-2 deg, notably 83F on 16th (87F in 1897 is the only reading on that date higher in all of the subsequent years, 1879 now tied second with 1958, 63). Also, a reading of 83F on May 13 was one short of the starter record of 84F (1900). By end of data 1879 held nine record low maxima (none tied, count 9.00). The most significant spell was in early November between two very warm intervals, with three days of highs in the mid 30s F (Nov 3-5) setting early season benchmarks (35 4th-5th).

    1879 also established nine surviving record low minima with one tie for a count of 8.50. Four were in November. There was one surviving record high minimum (64F tied with 1991 for May 16), and nights in the October to December warm spells often came within 3-5 F deg of later daily records, probably with today's urban situation there would have been numerous high min records set in those intervals).

    1880 -- This was another generally warm year (until Nov-Dec) and 21 record highs were set (for 1869-1900) and with three 2 two-way ties, two three-way ties and one four-way tie, the count was 16.91 (by 1900).  Five of these records have not been broken, for a survival percentage of 29%. The average year of record breaking was 1935, but if the five surviving records were to fall later this year or next year (Feb 29 cannot fall until 2024 at earliest), the average year of record breaking would move to 1957. The average deficit relative to eventual records was 5.4 deg but for the 16 that have been broken, the average is 7.1 deg. The two warm spells of late Feb-early Mar and late May remain among the more notable overall. The year established seven new low maximum records with one tie, the count was 6.5 ... most of these were in late November, still considered to be one of the most anomalous cold spells in the period of record. New early season benchmark of 23F (Nov 22) was one of five daily records set 19th to 26th. A max of 4 on Dec 30 was later broken in 1917 but is otherwise the second coldest December maximum and tied second coldest of any month with Feb 5, 1918. UK readers note that all this severe cold in eastern North America came just before a very cold and snowy period in mid-January 1881. 

    1880 also established eight surviving record low minima with one two-way tie and a five-way tie for a count of 6.70. Four were in November, with Nov 22 to 24 recording 13F, 14F and 14F. A reading of -6F on Dec 30 was removed by the -13 of 1917. There were four surviving record high minimum readings associated with the record high maxima, and these are 47F on Feb 13, 51F on Mar 4, and 73F, 72F on May 25-26 (the latter tied in 2018) for a count of 3.50. May 27 also 72F was later broken by 74F in 1908. The late June hot spell also produced near-record values of 77F on June 25-26.

    As this post is now quite lengthy, I plan to update this log in regular decade-length instalments. 

    The 1870s to 1880 were quite an active weather period with a lot of variations, and there was a major El Nino event around 1876-77. 

    The 1880s that will come next start out warm but turn considerably colder in general after mid-1882.

    1881 -- Although the winter remained cold, most of this year turned quite warm again, and set 16 "starter" highs (two tied for a count of 15.00). Of those, six still remain, two later tied, one untied in May, three untied in September, one tied also, and one later tied in December (count 5.00, survival percentage 33.3%, or 37.5% of shared dates). This is a relatively good production and also retention rate from this era. The reading of 101F on Sept 7 was only surpassed by Sept 2, 1953 (102F) and remains the latest 100F reading of any summer season. The record 93F on May 12 was the earliest occurrence of that temperature before May 10, 1970 and was not surpassed until April 1976. May 11 (90F) was not a starter record as 1896 reached 91F. September 1881 was warmest on record after adjustment for urban heat island (which was weak compared to more recent contenders). The average maximum in September 1881 was 80.8 F (1871-1900 mean 73.6). December 1881 was also a very mild month. The average for years that broke 1881 records was 1936 for the ten that have fallen, if the other six fell this year, that average would change to 1968. The ten records broken were eventually surpassed by an average of 5.9 deg which drops to 3.7 if the records are averaged in also. The year had nine record low maxima by end of the data set, of which three were tied, so the count is 7.50. One of those was 50F on Oct 5th, between record highs on 1st and 8th. 

    1881 also established six surviving record low minima with three two-way ties for a count of 4.50. Two were in the same brief cold interval between the October record highs. 35F on Oct 5th remains the earliest on record for that reading. For record high minima, the May heat records had minima in the mid 60s which were recently broken, but September 7th (79F) is still tied with 2nd (1898) as high September minimum. Three other records survived from the late Sept to Oct 1st warm spell (two of these since tied) -- 75F on 27th the most impressive of them. Oct 31 shares a record high min with 1961. The December warmth was not as able to sustain its modest record high minima. The total count is five shared dates, count of 3.50.

    1882 _ This year turned considerably colder than the previous four to six year relative warm spell. The idea that Krakatoa caused the cold 1880s must be partly wrong because 1882 and 1883 were generally cold, Krakatoa erupted in late August 1883. It is more likely that cold around 1884-1885 can be attributed to that volcanic dust veil. As a result of this trend, only four record highs were set in 1882, one tied later in 1888, for a count of 3.50 (similar to 1875 and slightly higher than 1893). The average year for breaking records set in 1882 was 1928. The average eventual surplus of the record high was 9.5 degrees. The year eventually had six surviving low maximum records, one tied for a count of 5.50; a high reading of 6 on Jan 24 1882 is a monthly record which has been surpassed by 4 F in Feb and 2 F in Dec. 

    The year established only three record low minima (count 3.00), with -6 also on Jan 24th the most impressive; the others were in early December. There were no high minima that survived but 48F (Mar 2) was only edged out by 50F in 1972 and 1991.

    1883 _ This was another quite cold year, March and September in particular were close to being coldest on record. However, it was noted in the comparative stats for NYC and Toronto that NYC ran a bit closer to normal at times, suggesting a strong gradient within a generally cold pattern. This may be why 1883 managed to produce even eight "starter" record highs; with no ties before 1900 the count was 8.00.  By 1914 this year's count was already down to 4.5. The average year for breaking records set in 1883 was 1925. The average eventual surplus of the record high was 8.5 degrees. The year eventually had ten surviving low maximum records, two tied for a count of 9.00; September 9-12 was exceptional with four maxima in the low 60s, three setting records. Parts of March were also anomalously cold.  

    The year established only five record low minima with one tied (count 4.50), but this is deceptive, 1883 turned very cold at the same time as 1885 on several occasions and that was a really dominant cold year (only one record from a very cold March for example). The most significant cold minimum was probably 43F on Sept 10 which was the earliest autumn reading that cold. The year managed to take down one high minimum, a rather weak one that has not been surpassed or tied, 73F on June 7th but this is several degrees lower than most date records in early June. It will very likely fall soon, having been nudged by 72F in 1984 in advance of several higher readings in a heat wave just developing on that date. (count 1.00).

    1884 _ This year was not quite as cold as the two on either side of it, and had some limited warm spells. The production of starter record highs was about average (which is 11.4), at 12.00 from 14 records, including four tied with other years in the starter era (1869-1900). About half of these were in October. The average for years breaking records set in 1884 was 1921. The average surplus of the eventual record high was 10.6 deg. The year produced eleven record low maxima, one of which has become a four-way tie. That makes the count 10.25. One date held is leap year day Feb 29th. 7 for Dec 20 is a notable record low max. 

    The year also established four record low minima, one of which was tied (count 3.50). The low of -3 on Dec 20 was later broken by 1942 (-4F) so if we were tracking these records the original count would have certainly been higher. There were surprisingly four record high minima, one is now a three-way tie and another a two-way tie, so the count is 2.83. September 9-10 have minima of 77F, the highest values since these were set are 76 and 74 (both in the past decade).

    1885 _ Another very cold year, in particular Feb-Mar. There were ten record highs set, with a count of 7.25 as of 1900, from four ordinary ties and one four-way tie among those. None survived to the present time. One record (Apr 22) may be somewhat invalid as 1842 was likely warmer (it hit 90F at Toronto and 80F at Providence RI). The average of years that broke these records was 1926. The average surplus of eventual record highs was 7.3 F deg. The year established 8 record low maxima surviving to present time, with the count 6.33. The interval Mar 17 to 23 had four of these with maximum readings as low as 21F during a week of below-freezing temperatures (normal highs near 50F by this time).

    There were also eight record low minima, with three ties for a count of 6.50. Mar 21 had 10F. One high minimum record (80F on July 25) survives.

    1886 _ This year managed to produce 16 record highs in the starter era (1869-1900) and a count of 13.83 from three ordinary ties and one three-way tie among those. All have been broken eventually. The average for years breaking these records was 1928, and the eventual margin of final record highs over them was 10.4 deg. The year produced eight record low maxima of which one was later tied three times, for a count of 7.25.

    There were ten record low minima which survived to end of the data, with three ties and two more three-way ties, for a count of 7.17, and also the year's lowest temperature of -4 on Feb 5 fell to -6 on that date in 1918. There were no record high minima, in the prolonged April warm spell the closest reading to eventual record high minima was 58 (Apr 22) which had already been surpassed by 59 in 1885 and eventually also by 60F in 1926, 1977 and the record 62F in 2016.

    1887 _ This year was near average for the starter era producing 11 record highs, 8 exclusively held, two tied and one four-way tie. A reading of 96F on July 16th was not a starter record (98F 1879) but was warmer than many others in July during that period. 79F on April 10 had been edged out previously by 80F in 1871. These records have all been broken with the average date of that being 1923. The average surplus of the eventual record high was 10.6 deg. Only four eventual record low maxima come from 1887 and one was a three-way tie eventually, so the count is now 3.33. That is higher than a long-term average but lower than the period average. The 29F max on March 29th is a late season benchmark although 30F on April 7, 1982 was close and forms the next benchmark (latest so cold in spring or perhaps end of winter).

    There were five surviving record lows, two ties making the count 4.00. One record high minimum occurred on Dec 14 (53F) -- the high on same date only 58F and not close to the starter and eventual period of data record of 64F (1879). I would picture this being a foggy of hazy sort of very late autumnal day with the next day a bit cooler and wet (0.70" rain).

    1888 _ The year started out rather cold and returned to that pattern in the early autumn, but other parts of the year were somewhat warmer. A total of 11 record highs were set in the starter era (1869-1900) and two were ties for a count of 10.0. Two of these records (in June) have survived to be eventual ultimate records. The nine that have been broken were first passed by 1928 on average, but if the two June records fall this year, that would change to 1944. The average surplus of eventual record highs to these nine broken would be 7.0 F deg, which falls to 5.7 if the two unbroken marks are included.

    This year was most famous for the "Blizzard of 1888" (March 12-13) which dropped  19.5" at NYC and 30-50 inches in the regions north of the city. That had an impact on temperatures for the rest of March. The year set a total of 14 low maxima, one tied with another later year, and another tied with two, for a count of 12.83 which surpasses even coldest year 1875 (14 also, count 11.33). One of these was 12F at the end of the Blizzard (March 13th). Another cold spell later included a max of 20F on March 23rd which is a late season benchmark. There were early cold benchmarks set in October (47F max 3rd, 43F max 9th). It was also record cold in the CET records at around this time, and rebounded to record warmth in late October which was also similar (Nov 1 for NYC).

    The year also had 17 record low minima, with the count 13.25 (two ordinary ties, three three-way ties, one four-way tie). At the end of the Blizzard, three record lows were set, 6F on March 13th was second coldest for the month. It had already been very cold at times in the preceding winter, with zero F on Jan 22 and 1F on Feb 16 setting records. Later in March it was 12 on March 24. In the autumn, 46F on Sept 7 was an early season benchmark, and a total of five more record lows were set in early October (35F on 10th). The year also had two surviving record high minima, 77F on June 23rd (second highest for the date is 76F in 1909, 1910 and 2017), and 50F on Dec 17 was tied in 2015, for a count of 1.50 high minima at this point.

    ______________________________________________________________________

    1889 _ Another famous weather event occurred at the end of May 1889, the Johnstown PA flood from excessive rainfalls but this had no direct impact on the NYC records. The temperatures reflected a rather active storm track at several times during the year (there was also a tornadic wind event in the northeastern states that did damage in Brooklyn NY on January 9th, 1889 -- the maximum temperature at NYC was 54, two degrees below the starter record high from 1876). There was a very mild December to start the generally very mild winter of 1889-90. The year 1889 set 10 record highs, one being an ordinary tie and another a three-way tie eventually, so the count was 8.83 by 1900 (it was 9.5 at end of the year as ties were mainly later in the starter era). None of these records managed to survive (one made it as far as Dec 2015). The average year breaking these records was 1932. The average eventual margin of the record highs was 10.1 F deg. The maximum for the year was only 91F (tied with 1884 and 2004 as second lowest annual maximum, 1902 topped out at 90F) but it first appeared on May 10th which fell one degree short of the 1896 mark so it was a daily record for seven years (not counted in this analysis). The year also set four record low maxima (untied, count 4.00). Three of these were in the late autumn. 

    There were only two (untied) record lows (count 2.00) and no record high minima for 1889. 45F on Jan 17th was tied in 1913 and beaten by 46F in 1990, similar to how the day's maximum was treated. The very warm May and then mild December spells came within a few degrees also.

    _______________________________________________________

    1890 _ After a very mild winter the rest of the year settled into a more moderate warmth with occasional cold spells. While Britain had a very cold December, the weather in NYC was near normal. The year had 18 record highs in the starter era (1869-90), with two ties the count was 17.00. More than half of these were before mid-March. November brought three more. Two remain as eventual records, one has been tied so the count for that is 1.50, a survival rate of 8.8%. The average of years breaking the 16 broken records is 1938. Counting the one now tied, 17 records have not maintained a lead past an average date of 1942. If the two records were to fall in 2022, that average would change to 1947. As noted below, Jan 2 (63F) was of starter record calibre but had already lost to 1876 (the eventual record) for that date. 1890 is the first year in our study not to retain any record low maxima. 70 on July 20th was one degree warmer than the 1869 record. 69 on Aug 10th was a record until 68 in 1931 (later tied and the eventual record). 

    Seven dates managed to retain record low minimum status, two tied later (count 6.00). There were four consecutive from July 20-23. The year also set two high minima, one later tied, for a count of 1.50.

    The decade of 1891 to 1900 set almost 40% of the starter records with a count of 141.75, and it retained 16.91 as eventual records counting ties as .50, .33 or .25 .. while a random expectation for that is 24.1, the decade did a lot better than the two previous which only retained 11 and 8.5 respectively (10 in total were 1880-81). The non-decade of 1869-70 retained no records to the end. So either there was some natural warming of climate in the 1890s to 1900, or the urban heat island began to assist some formerly marginal cases to break records -- it was probably a combination. The years 1895 and 1900 did particularly well at retaining record highs, while 1896 and 1898 set quite a few but failed to retain most of them to the end of the data period (which is today because I am always editing these posts when NYC breaks records). 

    1891 _ This year was often quite warm, especially the summer and autumn into December, and produced 19 record highs of which two were tied once, and two more tied twice in the starter era (1869-1900) for a count of 16.67. Of these, five still survive, two have been tied twice since then and another tied once for a count of 3.33. The survival rate is therefore 20% (3.33/16.67), although 26.3% of the original records are still at least tied records now. The average year for breaking 14 of the 1891 records would be 1926, while if all five fell later this year the average would become 1951. The average surplus of eventual record highs compared to the 1891 values is 11.1 F deg but this would fall to 8.2 if the five sustained records were included. The year also produced five record low maxima. One was tied twice, and another tied once, for a count of 3.83. 43F on May 5 is a benchmark low maximum (latest so cold in spring) with 45F also, on May 6. 

    There were four (all untied) record low minima during the year, 32F on May 6 is another benchmark and the latest air frost in the spring season at NYC. Meanwhile there were four record high minima. 78F on June 16 (warmest since 76F in 1957), 81F on Aug 11 (tied in 1896), 76F on Aug 24 and 72F on Sep 28, for a count of 3.50. Dec 23rd had 51 (eventual record high minimum 56F 1990).

    1892 _ This was a somewhat colder year which produced 13 records, one tied twice, for a count of 12.33. Of those, two survive, one having been tied three times for a count of 1.25. This is a survival rate of 10.1% (15.4% in terms of surviving as at least a tie). The most significant warm spells were in early April which produced the one surviving untied record high, and late July. The average year breaking 1892 records was 1937. This would change to 1950 if the two surviving records were broken at the next opportunity. The average surplus of the eventual record high over the 1892 broken values is 5.9 F deg (the smallest so far in the series) which falls further to 5.0 if the two surviving records are included. The year produced only two low maxima that have survived and one is now a four-way tie for a count of 1.25. 

    The year has one surviving record low, 57F on July 17th. There were three record high minima in the early April warm spell, 59F Apr 3 (tied 2015), 62F and 60F on 4th and 5th untied. Also June 20th set a high minimum of 76F. The count for four records is 3.50. A minimum of 78F on July 26 was broken by 79F in 1979.

    1893 _ This year turned quite cold in general, and produced only four starter highs for the period 1869-1900. Two were tied for a count of only 3.00, the lowest of the starter period and lower than all following years until tied in 1943, then most of the others also except for those which set no new records mostly late in the series, and 1957, 1960, 1968, 1981 and more frequent recent years (with one or two new records).  The four records were broken on average by 1926, and the margin of the eventual record high was 5.75 deg. While not very prolific this year's few records were not really obliterated. There were also four low maximum records sustained to end of the data, with one tied (count 3.50). 

    There were six record minimum temperatures, three ordinary ties, and one four-way tie, and even a five-way tie (count 2.95). The most significant cold spell was in mid-January, a low of +1 on 16th tied in 2004. There were no record high minima in 1893.

    1894 _ Although somewhat warmer again, 1894 only set a total of ten starter record highs, with three ties the count was 8.50. None of these survived to the end of the data set. One was tied before the end of the starter era in 1897 (Sept 11). The average year breaking these records was 1921. The margin of the eventual record highs averaged 8.3 F deg. There were nine record low maxima during the year, one ordinary tie, and one five-way tie, the count was 7.70.

    Despite the high count of record low maxima, only three surviving low minima occurred, one being tied later for a count of just 2.50. There were no record high maxima surviving by end of the data. 46F on Mar 6 survived to 1979 (49F, eventually 50F by 2011).

    1895 _ This was a highly variable year for temperatures, with some prolific heat waves at far ends of the summer season (late May, mid- September) but also a very cold February and early March. December also had a very mild second half. The year set a total of 24 record high maxima with four ties, a count of 22.00, second only to 1913 in terms of the number of records held at end of a year (under the starter period rules). As one of the ties came in 1897 the count was 22.50 until then. Nine days retain a share of an eventual record, with three ordinary ties and one three-way tie for a count of 6.83. This count was 8.83 until Nov 1975 and 7.83 until Dec 1984. This is a survival rate of 31.1% (33.3% of days not removed as at least tied). 1895 is now tied with 1966 in fifth place for the count of record highs. It has more than any year in the period 2002-20 (although several of those are close behind). There are two separate four-day consecutive record intervals (both with one or two eventual ties) and this is only surpassed by five in late August and early September of 1953,  and was matched in 1925 although without any ties there. In 2001 there was a four-day spell of record highs but one was later broken. Longer spells have occurred before being partially broken later. For the 15 records now broken, the average year that first did so was 1935, but if all nine of the records fell later this year, that would change to 1968. For the 15 broken records the average eventual surplus is 6.9 F deg but this would change to 4.3 F deg if the nine sustained records were included. 

    There were also three record low maxima in 1895, two in February and one in October, with one tie the count is 2.50. 

    The year produced five record low minima, with two ties the count is 4.00. The most significant is -4F on Feb 6th. The hot spells also produced a total of seven surviving record high minima, there were two in the early June spell (June 1 77F, and June 2 76F tied with 1918 -- 75F on May 31 was later broken by 76F in 1987), and four in September, in addition to one in November, for a count of 5.50. A number of the mild late December days had minima that were later edged out by 2-3 degrees.

    1896 _ More intervals of very warm weather developed in April and May of 1896, and through parts of the summer and autumn. There were 21 high maximum records, with just one tie, for a count of 20.5. Only one of these, Nov. 27, survived to the present, a survival rate of only 4.9%. The count as recently as 1970 was however 9.00. The average year breaking 1896 record highs was 1953; if the Nov. 27 record falls this year, that average will change to 1956. The average surplus of eventual record highs was 6.3 F deg which reduces to 6.0 including the sustained record. The year produced just three surviving low maximum records, the most notable is Feb 17 (7F), a benchmark value and just two days after a record high.

    The year also produced three untied record low minima, including -5F on Feb 17, and five record high minima including 47F on Feb 29th (tied in 2016), three readings in the low 80s in the August heat wave (9th-11th, two are ties), and 60F on Nov 27 remains a record and was a benchmark until slightly higher readings in Dec 2013 and 2015.

    1897 _ This year was not quite as warm, and produced only ten record highs, three of which were tied, and another in a three-way tie, for a count of 7.83. Only one record remains (Oct 16) for a survival rate of 12.8%. The average year breaking these 1897 marks was only 1916, which would change to 1927 if the surviving record fell this year. The average surplus of eventual records is 12.2 F deg, which reduces to 11.0 if the surviving record is included. The year produced only three low maxima (count 2.50), two were in late July (both 68F). This was around the same time that Toronto was setting a 24h rainfall record. 

    During the year there were also just three low minima (count 2.50). There was one record high minimum (67F) with the Oct. 16 record max of 87F.

    1898 _ This year had a rather hot summer and produced 18 daily record highs in the starter era (1869-1900), with three ordinary ties and one three-way tie, the count was 15.83. None have survived all the way to the present time. The average of years breaking these records was 1927. The average surplus of the eventual record highs is 6.9 F deg. 1898 accounts for just two record low maxima, 41F on April 28, and 28F on Nov 27 (later tied in 1932) for a count of 1.50. 

    The year managed just a tied record minimum (count 0.5) in July, but the September heat wave had a run of very warm nights that set five consecutive high minimum records (Sep 1-5, 76F, 79F, 78F, 78F, 77F), of which the first and last have become four-way ties, the middle three are still exclusive to 1898 despite hotter days that broke the maximum records (2nd is tied with 7th 1881 as September monthly maximum). The earlier July heat wave only managed a 75F on July 2nd, well short of several other years. Oct 4 and 5 also have record high minima that are also monthly highs (75F, 75F), despite highs reaching only the low 80s (not starter record highs). So from seven in total the count is 5.50.

    ________________________________________

    1899 _ The most remembered weather event of this year was a February deep freeze and east coast snowstorm mid-month, but much of the year was quite warm and set 18 starter record highs with two ordinary ties and one three-way tie for a count of 16.33. Only one tied record (Dec 19th) survived, a rate of just 3.4%. The average year breaking these 1899 records was 1925, which would become 1930 if the tied record were broken later this year. The average surplus of the eventual record highs was 7.8 F deg which would be reduced to 7.5 F if the surviving record was included. The February cold wave set four low maximum records (10th-13th, 7F, 9F, 9F, 11F), with 16" snow 12th-13th. Two more low maxima were set on Oct 1-2 (51F, 49F, earliest sub-50F maximum of fall season). The count was 6.0 for the year.

    The February cold spell only took down two daily minima, one tied earlier in 1885, the 12th-13th later broken by 1914. The lowest reading was -6 (10th). Oct 3rd also took a one-third share, for a total of three record lows and a count of 1.83. There was just one tied record high minimum, 76F (June 15th) later tied in 1945 and 1956. (count 0.33)

    1900 _ This is the last year of the starter record period, but its count would be the same if excluded since it has to break or tie highest values of the earlier 31 years to qualify. 1900 had numerous very warm spells and racked up a total of 22 records of which five were ordinary ties and one a four-way tie (count 18.75). This was third highest of the starter era. Three survived to the present time (two in May, one in November), so the survival rate is 16.0 per cent. May, July, August, October and November had the most notable warm spells. The average of years breaking 1900 record highs is 1932, which would change to 1944 if the three surviving records were broken later this year. The average surplus of the eventual record highs over 1900 record values is 6.8 F deg which drops to 5.8 if the three surviving records are also counted in. The average starter record (1869-1900) falls 7.2 F short (including those that have survived) of the eventual set, so 1900 has done slightly better than that average. By 1901-30, the maximum just from that thirty years (even in the numerous cases that did not break starter records) came a bit closer at 6.0 F short. Then in the modern warmer climate, the average maximum reading 1991-2020 falls just 3.6 F short of the period records (not surprising since it has set quite a few of them for zero contributions to the total to be averaged). Meanwhile, four record low maxima survive to end of the data, one tied, for a count of 3.5 -- all of them are in a cold period of late February into March. 

    There is only one surviving record low minimum, 5F on Feb 27th. There were three surviving record high minima, 46F on Jan 20, 68F on May 16, and 81F on July 18 (tied 2013), for a count of 2.50. Later spells produced values that were not quite able to hold or in one case had already been eclipsed in the 1890s. These non records include 79F on Aug 11th, 77F, 76F on Aug 26-27th (broken by 78F and 79F in 1948), 69F on Oct 5 and 56F on Nov 20th. I would imagine that had these weather events taken place in the late 20th century or more recently, some other record high minima would have been set in 1900. The annual average minimum was 2 F deg warmer than the average of 1869-1899 and only 1 F below the average for 1981-2020 (the period which I have assumed represents an urban heat island increase of 0.9 to 1.1 C or 1.6-2.0 F deg over those earlier years).

     The 1901-10 decade broke a total of 67 starter records and tied 14. This is a fairly random outcome, as 10 years vs 32 previous records should break (10/42) of the records, or about 87. The total record count was 90.08, however some days of the year saw two or three broken records in this decade. Overall the 1901-10 decade did not outpace the starter era. In the annual analyses to follow, we can introduce one new statistic, average amount by which each year broke records. The other stats being tracked will continue here. As more years are introduced, the expectation of the number of records gradually falls. It was a constant 11.4 in the starter era. In this decade, it falls to 8.7 by 1910. This will also be tracked to give a better understanding of the record counts.

    1901 _ This year is mostly remembered for its hot spell in early summer. Otherwise it was rarely very warm apart from a spell in late October. The year managed to break or tie nine starter records (one three-way tie and a four-way tie created) for a count of 7.58. With a count of 1.5 surviving record highs, the survival rate is 19.8%. The average margin by which 1901 records replaced nine starter records (tie equals zero here) is 2.6 deg. The average year replacing 1901 records was 1916 (but would increase to 1939 if the two surviving records were broken this summer). The average margin of surplus of record highs at end of data to 1901 records is 7.9 F deg, which drops to 6.1 F deg counting the unbroken records. Oct 23 (75F) was one degree below the starter record high of 1871, 1900 (76F).

    1901 also set four record low maxima, two tied, for a count of 3.00. (while the expected number of records to end of the year is around 11.2, the end of period random expectation for all years is 2.4).

    There were no record low minima, and a count of 1.33 record high minima, the unbroken one coming on July 2 (82F). The tied record was 53F on Dec 14 later tied in 2001 and 2015.

    1902 _ This year had warm March and November spells. There were ten new record highs, but with four ties of starter highs, the count was 8.00. In addition to these, 66F on Mar 12 was not a record (71F 1890) and 83F on Apr 23 also not a record (84F 1886, 1925). None of these records survived past 1972. The average excess over starter era records for the ten was just 1.7 F deg. The average surplus of eventual record highs over 1902 records was 13.1 F deg. That is larger than most starter era margins. The average year breaking a 1902 record high was 1927. There were three record low maxima, one on May 28 and two in mid-December. 1902 has the lowest annual maximum of any year in the data set (only 90F). 

    1902 holds just a half share of one record low (43F May 29 tied 1884). (count 0.50) It also has a third share in one record high minimum on May 24 (70F), count 0.33.

    1903 _ This year had a very warm spring and broke or tied 18 starter records, with two ties among them for a count of 17.00. Nov 5 (66F) also fell one degree short of breaking the 1900 record high. None of these managed to survive the rest of the record however. The random expectation by 1903 has fallen to 10.4 so this is a surplus of almost 70%. The average 1903 record added 3.8 F deg to the records broken (it should be noted that this stat can begin to include periods beyond the starter era although 1903 did not break any 1901 or 1902 set records.) The average year breaking the 1903 records was 1926, and the average margin of the eventual record high over 1903 record highs is 12.1 F deg. The year set six low maximum records, and had a count of 5.25. These were mainly in the summer which was generally cooler than the spring and autumn (in relative terms).

    The counts of record low and record high minima are similar, three (count 2.50) record lows and four (count 2.83) record highs. A record high minimum on April 30 was followed by a tied record low on May 2nd.

    1904 _ This was a much colder year. Even so, it managed to break five starter records and tie four others for a count of 6.83. The average margin of increase over former records was only 1.7 F deg. None of these records lasted very long, most were gone before the end of the next decade and the average year of extinction was 1915. Eventual record highs averaged a surplus of 12.9 F deg. By contrast the year produced five record low maxima that survived to end of data (count 4.00), the most significant one being 37F on April 20, a benchmark value. 

    There were also just two record low minima (count 2.00), and one unbroken record high minimum (42F on Feb 6).

    1905 _ This year had some warm spells in spring and autumn and a brief heat wave in July. Otherwise it was another rather cool year. It managed to break ten established records and tied four others for a count of 11.83. (vs 9.8 random expectation). The average margin of increase for these 14 new or tied values was 3.2 F deg.
