  1. Would quite like a downward correction on this one just so that the latest 18C day can still also be the latest 19C day!
  2. Interesting, I lived in Selly Oak 2015-2018 and didn't even know it had its own hospital! The enormous QE next to the university seems to be the centre for most things now.
  3. Just to note that, with the official data in, we have indeed set a new record of 45 days.
  4. I'm fully aware of what you're saying, so I'm not going to argue with you, other than to say that Craig is not an idiot. His crazy punts have been a custom on this forum for years and you're taking them far too seriously.

    Spring 2013

    A fascinating season, with March of course being the highlight. Down in Chelmsford we had two snowy spells. The second one (around the equinox) brought four inches of powder snow but winds were light so we didn't get any drifting. Some exceptionally low maxima for 12+ hour days, barely climbing above freezing on a number of occasions. April started off very cold with easterlies bringing snow showers and some beautiful frosts. Sunnier and warmer mid-month before cooling down again. May was consistently cool but quite a pleasant month. Very few people realise that, in CET terms, Spring 2013 was colder than any in the 20th century.
  6. Yeah, and I thought he was crazy for going for 9°C in December 2015...
  7. Not necessarily, as it depends on where the cold air is being sourced from. Given some of the unprecedented temperature anomalies we've seen over the Arctic in recent years then perhaps cold spells from direct northerlies will be far less potent than they used to be, in which case "0.8°C less severe" may be an underestimate. However, we have seen some truly brutal cold-pooling over Siberia in recent years, which many believe could be a consequence of a warm Arctic (often referred to as "warm Arctic, cold continents"). So it may in fact be the case that we see Siberian-sourced cold spells increase in severity. The remarkably cold weather we witnessed in late February and early March of this year (upper-air temperatures briefly touching -17°C; you'd probably have to go back to 1987 to beat that!) perhaps demonstrates this. And what of cold sea-surface temperatures in the north Atlantic due to a weakening AMOC? If we see cooling in the right regions then maybe this could, to an extent, negate the effects of warmer Arctic air because the water over which the air is travelling becomes colder and hence we see less modulation? The same goes for cold-and-snow events off the back of Winter depressions: perhaps marginal events see more snow whereas previously we may have just had cold rain?
  8. Summer 1976 is currently top at 23.47C. A ranked list can be found here: https://www.metoffice.gov.uk/hadobs/hadcet/ssn_HadCET_max_sort.txt
  9. A lot of people in this country struggle to get a tan if they go outside; they just burn instead. Many people are wary of their health and as such will stay inside when necessary.
  10. With Summer 2018 looking to finish above 17°C, I thought I'd look at how it so far compares with all other 17°C-and-over Summers (nine in total) in terms of the numbers of "hot days". I've plotted the number of daily means above or equal to each of 20°C, 21°C, 22°C, 23°C, and 24°C in each of these Summers alongside the current corresponding figures for Summer 2018 (August figures are provisional). Each of the current top nine are shown in order of lowest rank to highest rank from left to right, followed by 2018. Apologies about the vertical axis labels which should read "above or equal to" instead of just "above". The number of 20°C+ days shows a fairly even spread, with 1995 the only one to really buck the trend at a whopping 26. As very hot Summers go, 2018 seems pretty normal in this respect, with 15. Going up to 21°C+ days, 2018 drops down very quickly to just three! The Summers of 1976 and 1995 dominate with 14 and 15 respectively, while 1826, with five days, and 1846, with six days, are the next lowest after 2018. Going up again to 22°C+ days, 1976 destroys all competition with 12 days. The Summers of 1826, 1846, and 2018 are the poorest once more with one, one, and two days respectively. The only current top-five Summer to not record any 23°C+ days was 1826, while 1947 also nicked one. Three of the top five, 1976, 1995, and 2006, recorded 24°C+ days. So in this respect it seems that 2018 is really quite different from more recent very hot Summers; it fits in much better with those of the 1800s, where the heat was much more consistent, but never quite achieving any utterly extraordinary spikes like those of early July 1976 or early August 1995.
  11. Indeed, I was under the impression that it was an evolutionary adaptation: those with paler skin absorb more UV light leading to greater vitamin D production. Which, of course, makes perfect sense given average UV levels in the UK relative to other European countries.
  12. Below I've listed all the days of the top nine Summers (all those of 17.00°C and above) that have exceeded 2018's highest daily mean of 22.5°C on the 27thJuly. 1826 (rank = 2) 27th June (22.8°C) 1846 (rank = 6) None, highest was 22nd June 1846 (22.0°C) 1933 (rank = 9) None, highest was 4th August 1933 (22.2°C) 1947 (rank = 8 ) 3rd June 1947 (23.0°C) 1976 (rank = 1) 28th June 1976 (22.6°C) 1st-7th July 1976 (22.9°C, 22.8°C, 24.6°C, 24.7°C, 23.9°C, 23.3°C, 22.6°C); part of a 12-day run from 26th June – 7th July above 22°C 1983 (rank = 7) 12th, 13th July 1983 (22.6°C, 22.7°C) 1995 (rank = 3) 31st July – 3rd August 1995 (23.4°C, 24.9°C, 24.6°C, 23.4°C) 2003 (rank = 4) 15th, 16th July 2003 (22.6°C, 22.7°C) 5th August 2003 (23.1°C) 9th August 2003 (23.9°C) 2006 (rank = 5) 2nd July 2006 (22.7°C) 19th, 20th July 2006 (24.5°C, 22.7°C) 25th, 26th July 2006 (22.7°C, 23.2°C)
  13. My memory for weather only really goes back to December 2010, so this is my list based on all months since then. January 2013: Good cold and snowy spell in the middle of the month. February 2012: Extremely varied, with bitter easterlies and snow in the first half to warmth and sunshine in the second. March 2013/2018: The former was snowy and saw some exceptionally cold maxima late on in the month; the latter saw two very extreme cold snaps with some superb drifting snow. April 2012: Perhaps the most sunshine-and-showers month I can remember, with some beautiful convective cloudscapes producing plenty of showery rain and hail. May 2012: Another varied month, with very cool but convective weather in the opening two thirds, followed up by a remarkable heatwave. June 2016: Really struggled with June, but I'll go with 2016 because of how remarkably cloudy it was. July 2014/2015: The former was a superbly stormy month, with many nights of intense thunderstorms; the latter was extremely varied with record-breaking heat in the opening days and a run of exceptionally cool weather to close the month. August: Don't know! September: Don't know! October 2012/2015: The former was cool, and featured the only falling snow I've witnessed in October; the latter, barring a few days at the end, was cool, crisp, and seasonal. November 2016: A cool, crisp month, with a wintry feel owing to its plentiful frosty mornings (sadly no snow). December 2010: Two fantastic snowy spells; deepest level snow I've ever seen; coldest temperature IMBY; consistently below freezing. Need I say more? Tally per year: 2010: 1 2011: 0 2012: 4 2013: 2 2014: 1 2015: 2 2016: 2 2017: 0 2018: 1
