Winter 1988-89 Winter 1991-92 February 1993 Winter 2016-17 Winter 2018-19 Winter 2021-22 February 2023

Reminds me more of 2018. 2012 did have a northerly at the end but it was never warm though had a milder period just before the cold snap, it didn't achieve 20C anywhere in the country.

It has now finally been released. September 2023 CET was equal to June (at least to one decimal point, I'm sure others will tell us how close it was with multiple decimal points) with 17.0C. Warmest ever recorded.

I was informed that the lack of staff and resources is likely why the CET has been poor at getting updates the past week according to Dan Harris who is a Met. Annoying but at least there's a possible known reason why this has been the case.

Cool, sunny months in Dublin's records since 1942. December 2022 76.2 hrs with a tmean of 4.4C. May 2021 214.2 hrs with a tmean of only 9.2C. April 2021 209.9 hrs with a tmean of only 5.6C, the coldest on record. February 2018 108.9 hrs with a tmean of 3.4C. November 2016 97.5 hrs with a tmean of 5.6C. June 2015 204.3 hrs with a tmean of 12.9C. June 2013 210.4 hrs with a tmean of 12.7C. December 2010 60.3 hrs with a tmean of -0.1C. Not a very sunny month but sunnier than average and warrants a mention. August 2010 216.0 hrs with a tmean of 13.9C. May 2010 234.7 hrs with a tmean of 9.6C. January 2010 86.3 hrs with a tmean of 1.7C. October 2008 120.9 hrs with a tmean of 8.9c. October 2003 115.6 hrs with a tmean of 9.0C. September 1986 195.4 hrs with a tmean of 11.8C. The sunniest on record. May 1975 255.8 hrs with a tmean of only 9.4C. June 1962 202.8 hrs with a tmean of 12.4C. March 1962 128.8 hrs with a tmean of 3.5C. Second coldest on record. December 1961 76.5 hrs with a tmean of 4.0C. January 1959 99.3 hrs with a tmean of 3.1C. The sunniest on record. October 1955 139.7 hrs with a tmean of 8.7C. March 1955 171.7 hrs with a tmean of only 4.2C. 4th coldest on record and 3rd sunniest. September 1954 161.4 hrs with a tmean of 11.7C.

And 2022.

Simon King is referring to the CET. A bit of a misleading article though to use the CET as a representation of the whole UK in the title and coming to that conclusion a few days early. On the UK mean temp, September was cooler than both June and August but warmer than July.

Joint record with 2006 for the UK national series beginning in 1884 for mean temp. Joint record with 1895 for mean max. Second warmest for mean min, behind 2006.

6 consecutive days in the overlapping spell of August/September 1906 is the most I'm aware of.

2023 is on 6 30C days for the UK so far (10th-13th June, 25th June and 7th July). How many more will be added this week?

That was 2016. It has happened 7 years since 1900.

The history of the July and August records. July 1911 36.1C 2006 36.5C 2015 36.7C 2019 38.7C 2022 40.3C August 1911 36.7C 1990 37.1C 2003 38.5C

I posted the stats last night in the summer chat thread.

Using the latest August estimates from Roostweather (image below for some of them). These are the summer 2023 stats I have calculated for the UK as a whole, anomalies or % of average are relative to the 1991-2020 climate. Mean temp 15.37C (+0.78C). Would be 8th warmest on record since 1884. Mean max temp 19.73C (+0.87C). Would be 15th warmest on record since 1884. Mean min temp 11.10C (+0.8C). Would be 2nd warmest on record since 1884, behind only 2003. Rainfall 287.1mm (113%). Wetter than average but only the wettest since 2020. Sunshine 526.4 hrs (104%). Skewed heavily by the very sunny June with a cloudy July/August.

Back then it was the era of the cold AMO anyway. Strong colder than average anomalies widespread in our North Atlantic region, granted the resolution of the NOAA maps back then ain't great.

Yes I am one of those. I blame it for my freak eidetic memory of stats no one cares for and unhealthy obsession of snow!

June - 9/10 July - 0/10 August - 3/10 Dublin, Ireland.

Pretty much summed up my view on this summer though I'd say "terrible" is generous for the atrocity of July 2023. Although I personally loathe July 2020 more, we've probably not had a summer month as "objectively bad" as July 2023 in a long long time. June 2012? August 2008?

Definitely some more anticyclonic influence for the south/southeast in 2009 but way deeper troughing in 2009 for the north giving a very wet month for Scotland and Ireland. 2023 average heights nationwide, probably from more settled periods balancing out with the exceptionally deep lows this month has had.

2000 would have been a close one.

Least yours is much neater!

I was only a little one in 2003 but reportedly, that was a horrendous autumn colour season here as the severe frosts in October 2003 brought down all the leaves in one single night. I'd sacrifice that though for the incredible thunderstorms, mountain blizzards Dublin had and outstanding Halloween geomagnetic storms. Hard to believe this was October here. Bullseye right for me.

Yeah what I posted was only one way of looking at things whilst the title suggested more of generally speaking the coldest and warmest weather occurring before solstices which cannot be found out as easily statistically. So whilst absolute max and absolute min values may have been recorded after the solstice in some years, they could have been from very localised warm days or cold nights whilst 2023 has both absolute and widespread nature going for it. If we use 2010 as an example that Crewe mentions, most of the widespread fine weather occurred on or before the summer solstice in 2010 and it became unsettled through the rest of the summer though was hardly all rainbows as there was a pronounced unsettled period 6th-9th June. The absolute max occurred on 9th July in Kent but by that point much of the country was under the influence of the Atlantic. The absolute min for winter 2010-11 occurred before the winter solstice on December 1st but the absolute min for winter 2009-10 occurred on January 8th and the most widespread, severe cold part of that winter was definitely the first 10 days of January.

Winters with the UK absolute min set before the solstice. 2022-23: -17.3C on 13th Dec 2021-22: -10.2C on 22nd Dec 2019-20: -10.3C on 1st Dec 2016-17: -12.1C on 21st Nov 2013-14: -8.1C on 25th Nov 2010-11: -21.1C on 1st Dec 2004-05: -15.2C on 19th Dec 1999-00: -14.0C on 20th Dec 1998-99: -13.1C on 6th/7th Dec 1992-93: -13.7C on 20th Dec 1991-92: -13.3C on 12th Dec 1989-90: -14.0C on 15th Dec 1988-89: -11.6C on 22nd Nov 1987-88: -11.5C on 10th Dec 1982-83: -15.1C on 17th Dec 1973-74: -17.5C on 1st Dec 1960-61: -12.2C on 11th Dec. However, this one would be equalled on 16th Jan too. 1955-56: -20.0C on 12th Dec. Though this winter is most known for a severe February. 1952-53: -15.0C on 25th Nov 1950-51: -18.3C on 15th Dec 1947-48: -17.2C on 19th Nov 1937-38: -21.7C on 13th Dec 1927-28: -17.8C on 17th/18th Dec 1925-26: -16.7C on 20th Dec 1922-23: -9.4C on 11th Dec 1920-21: -18.3C on 13th Dec 1919-20: -23.3C on 14th Nov 1905-06: -15.0C on 18th Nov 1904-05: -14.4C on 27th Nov Years where the UK absolute max was set before the summer solstice. 2000: 32.6C on 19th June 1980: 29.4C on 4th June 1978: 28.8C on 4th June 1974: 28.0C on 15th June 1965: 28.9C on 14th May 1960: 30.6C on 18th June 1950: 33.3C on 6th June 1947: 34.4C on 3rd June 1940: 32.8C on 9th June 1939: 32.2C on 7th June 1931: 28.3C on 14th June 1927: 29.4C on 16th June 1920: 27.8C on 17th June 1917: 33.9C on 17th June 1915: 32.2C on 8th June 1913: 29.4C on 16th June 1910: 28.9C on 20th June If we combine these two lists since 1900, the only years where the absolute max and min were set before their respective solstices if we go by winter first then summer... we get only 1974 and 1920 that this has happened. Of course this is only one way of looking at it. Those maxima and minima could have been from localised warm days or cold nights.
