  1. Indeed, the summer of 1816 was overall the 3rd coldest according to CET with only 1695 and 1725 being cooler. Eastern Europe and parts of Scandinavia had a fairly hot summer though. Annually 1816 was cold across the UK but not as cold as it was two years earlier in 1814.
  2. September 1st-September 2nd, 1816. An unusual early wintry cold snap was reported across many regions of the country in September 1816. Luke Howard at his thermometer based at Tottenham, London records a night minimum on the 2nd September of -1C with the description of “thick ice” and “hoar frost”, although doesn’t report snowfall. However... “The Morning Post“ reported that on the morning of the 2nd September, 1816 (3am) that heavy snowfall was recorded 2 miles up the road from Barnet. Similarly the “London Courier” on the 7th September, 1816 reports “hail and some snow reported in a neighbouring county” and also thick heavy ice. Up north in the “Caledonian Mercury” from Scotland we also have acknowledgement of snow falling in parts of England and the Grampians looking like winter. All of this of course, if the reports are accurate, would mean this could be potentially the earliest snowfall recorded over England. There were similar reports of snowfall along the southern coast at Brighton and Lewes. Also an American paper discussed the Summer of 1816 mentions snowfall in London on August 30th although I think this maybe an error as temperatures were above 15C in the capital on this day with lows of 12C. Maybe a hail event. September 1816 was a bit of a balmy month as over a week later highs of 23C were recorded in London. Incidentally Luke Howard records a high of only 9C at Tottenham on the 1st September which had it occurred 24 hours earlier surely would’ve been the lowest London summer temperature ever recorded. (See the Newspaper Articles below) 25th September, 1885 First official snowfall event of the season in London but I think it didn’t stay on the ground. 19th September, 1910 Snow flurries reported at Epsom but I can’t find any sources to back this claim. No reports in local newspapers either. Perhaps a mistaken hail event or sleet. 19th-20th September, 1919. The first major snowfall event on record across Scotland, Northern England and the southwest. Remarkable that it occurred a week after a heatwave. More here...https://www.netweather.tv/forum/topic/32640-heatwave-then-snow-september-1919/?ct=1600014765 It pretty much ends there...Higher grounds i.e Pennines, Grampians, Cairngorns typically can see snowfall in September each year although some heavy snow accumulations reported in 2003 across the Cairngorns. Orlando Whistlecraft also mentions snowfall in September 1799 but doesn’t mention locations. Even according to Whistlecraft September cold snaps/snowfall were rare and this was him writing in 1840. September 1807 was very cold across most of England (Coldest September CET) and Luke Howard at Plaistow, London records a minimum of -3C in the early morning of 13th September. The newspaper articles from 1816...
  3. I’ve just come back from Svalbard - I was battling daily with -23C conditions ?. Locals couldn’t believe how cold the autumn has been and conditions which many were not used to at this time of year. On Thursday I embarked on a voyage to the abandoned Soviet mining town of Pyramiden. It was the last trip of the season before early June. On the final approach to the docking area the captain of the boat was stunned by the amount of sea ice. Volumes not seen for at least a decade this early in the season. The pictures below are mine showing the extent...All that white stuff is Ice. Of course I had to also show you the sign to Pyramiden ??
  4. Found a couple of other sources about this month. A weather diary from Bristol by Dr Pole shows relatively the same temperatures but much harsher wintry conditions out West. Frequent heavy snowfalls reported mid-month and fairly wet. Also a quote from James Losh's Diary based in Newcastle. ''The last November (1807) has been by much the most severe November I ever remember - Indeed although the frost was not long continued without intervals of thaw, I apprehend that it's average cold has been fully equal to that of January in general. I do not believe that the season has not been unhealthy except for old and very delicate persons who have certainly died in great numbers. Flowers of all kind have been checked and the sowing of Wheat has been greatly impeded'' The following December was equally as cold but the Christmas period was slightly milder and 10C was recorded in London come Boxing day.
  5. 0.3C cooler than bloody October 1816 - the year with no summer ?
  6. The mid September heatwave of 1926 was very warm with temperatures hitting 32C in London and central France up to the high 30's!
  7. That long week heatwave at the end of July 1868
  8. Summer 2007 was worst in my opinion than 2012. I just remember summer 2007 (my GCSE year) constantly raining and never stopping. Our school hall flooded! Temperatures were struggling to get into the low 20's throughout June and July although there was a slight warm period at the start of August but that was it. I just hope 2019 isn't going this way as it certainly has the same vibe to it. 2012 was horrendously wet but days were more warmer and summery than 2007 when it was clearer I seem to remember.
  9. Try to find some reports on the 1800 drought from local newspapers at the time. Proved difficult but managed to find 4 quotes all from August 1800. I have also found an image of the Drought effects and it's extent from the Old World Drought Atlas.
  10. Interesting information there! I was only 5/6 years old during the 95/96 very hot and dry summers so I don't really remember much ? This 1800 summer heatwave pretty much kicked of series of very hot and dry summers especially 1801, 1805, 1806,1807 and 1808. A decade very much in contrast to the wet and fairly cool summers of the 1790's. As you can see in the table below average summer temperatures rose over 1 degree between the 1790's and 1800's.
  11. Around 219 years ago, back in 1800, May opened up with a pleasant burst of early summer-heat but June began cooler and was dull with cloudy and wet conditions and perhaps the locals were gearing up for another typical British summer - but what was coming up was nothing short than extraordinary. From the 23rd June to 23rd August no rain fell - it was hot, dry and clear with blue skies for practically two months (62 days - just under 9 weeks) ?. Temperatures in July remained in the mid to upper 20's every day and were sunny and clear. The high amount of heat and the dryness of the atmosphere would probably have made conditions very oppressive in London at that time, the jet streams most likely parking anticyclonic pressure over Great Britain and staying there for weeks on end, dragging up tropical air from the equator in a ''Spanish plume'' effect maybe? There was no relief from this heatwave from July into August as temperatures soared into the low 30's (maybe higher?), even the nights were very warm and humid with 25C recorded just before midnight on the 2nd August. The long heatwave and the general sultriness continued till the 23rd August when finally some showery weather returned with some relief but what an incredible Summer this was and totally the opposite of the fairly cool and wet summer of 1799. Data is from B.W Cary's stand in Central London - so there may have been different conditions in the North or out to the far west but It's probably a clear indication of what was going on in the southeast. I'd imagine though the heatwave probably did effect large areas of the country regardless.
  12. Only 4 days of rain so far this month. Could all change by next week.
