  1. Wasn't sure where to post this but fun fact...

    If this September comes out warmer than August for the CET, 2021 will join a very quirky exclusive club of years where April was colder than the preceding March and September warmer than the preceding August in the same calendar year. The only other year since 1659 that has happened was 1750. However, March 1750 was exceptionally mild (8.2C) rather than April being particularly cold (7.7C) relatively speaking.

    I have noticed this over the years and it does seem to be verifying, we get less wind. Take Valentia in Co. Karry, South West Ireland (So very windy spot). 1944 to 2010.

    I calculated more national means and this September as of the 22nd for Ireland is running as the calmest in a record since 1981 with 6.5 kts. 2014 holds the current record with 6.8 kts. Mind the past few days have tended to be windier - 22nd was windiest day since 13 August nationally speaking.

  3. Don't have any wind data for UK but for Ireland, 2021 had been the calmest January to August period since 2010 and that theme has continued into September with the mean average running even closer to 2010 (which was record calm for many stations).

    Particularly noticed the lack of wind this summer which was reportedly one of the calmest on record:

    I think the sunniest December recorded around 90-95 hours of sun. August 2008 was famously duller than February 2008 though.

    Indeed 93.3 hrs in December 2001. Image below is every month ranked sunniest to dullest for Heathrow as of July 2021. Reservations have to be made for months from September 2005 however as they were recorded with a K-Z sensor instead of C/S recorder.

    When was the last occasion when each month of the extended summer, May to September, recorded below-average sunshine and above-average rainfall widely across southern England? Not saying this year definitely will but I agree the 06Z GFS seems to show a return to the pattern of early August.

    Thinking back as far as 1978 I can't recall a previous occasion. 1974 perhaps? I have heard that year was 'legendary' for a mild wet winter and cool wet summer, kind-of an anti-1947.

    1968 was the last time according to central southern England/SE England regional series.

    Thanks, interesting to see the differences between Ireland and southern England, which my list was biased towards.

    I've heard people say that summer 2021 was not unlike 1968 (and 1977) both of which featured fine weather to the northwest and more unsettled weather to the southeast, 1968 in particular being notably bad. Wonder if that is a fair assessment? Going a bit OT I wonder if 1968 also had persistent extreme heat over eastern and south-eastern Europe, as this seemed to drive the repeated formation of lows close to southeast England this summer?

    The somewhat-controversial 1994 by contrast had strong Azores ridging, but I seem to remember it being more westerly towards the north and west - so one where the fine weather was concentrated in the south and east, perhaps.

    Not sure how I forgot 1949 as one of the best Irish summers too just after re-reading your initial post mentioning it.

    You would be correct about that 1968 comparison. This year has been running closely to 1968 so far in some aspects like the March 2021 high temperatures were the highest since 1968, April 1968 was the frostiest April on record for the UK before 2021 and 1968 had been the closest situation where the spring absolute max was achieved in March (it equalled April that year). It was a really weird year 1968 with a highly reduced westerly gradient.

    Going by anomaly maps, it wasn't a warm summer at all across Europe. Very different times then though.

  7. Well for Ireland, which can differ greatly at times to England like in 1968, the best summers of the 20th century going by stats I would say are:

    1995, 1976, 1955, 1983, 1989, 1959, 1933, 1975, 1969, 1911.

    1995 is hands down the best Irish summer.

    Other summers that had at least one exceptionally 'good month' (very warm, very sunny and or very dry): 

    1990 - Second consecutive very sunny July after 1989. 2 August 1990 was the hottest day on record in Dublin with 31C achieved (19 July 2006 would later equal this). Terrible June

    1947 - a pretty mixed June/July but August second best of the century after 1995. I often refer to it as the 'forgotten gem' as it was contender for best summer month of the century with only competition really being the likes of July 1989, August 1995 and August 1976 for overall warm, dry and sunny conditions. Locally in Dublin, August 1947 also contained the longest absolute drought of the century lasting up to mid-September. 

    1940 - a very sunny and warm June which still holds the monthly sunshine record for Northern Ireland to this day. August was also dry but otherwise a pretty meh summer. 

    1934 - a hot July with one of our most notable heatwaves of 20th century.

    1921 - similar to 1934 with a hot July and a notable heatwave. 

    1968 that I mentioned is a funny one. It wasn't an especially warm summer even here and in fact was on the relatively cool side but it was very sunny with a prolonged drought period through July into August.

  8. June was slightly sunnier than average locally, many days with sunny spells but few very sunny ones. July was well above average all thanks to an exceptional sunny 10-day spell from 16th to 25th and was the sunniest since 2013. First half of July was running as dull as July 2020 up until that so was a complete flip around. August up until 22nd was also exceptionally dull with only 48.7 hrs (absolutely atrocious), it has risen to 92.9 hrs as of the 26th and after today will now be sunnier than August 2020 which was the dullest on record here in Dublin. 

    What is it with 2021 and these big turn arounds? February, July and August this year all featured exceptional dull periods being masked by very sunny periods. EDIT: Even March to an extent.

    Seasonal total to 26 August is 463.9 hrs which is relatively below average (95% of 91-20 average) but way way sunnier than 2020 which was more than 120 hrs duller and the dullest on record. There's still time for it to reach average too but August will be dull.

  9. One of Ireland's most exceptional weather months without a doubt.

    It was nationally Ireland's hottest month on record and remains so with persistent high pressure and hot easterly winds a lot of the time. The national record max temperature for August was equalled with 31.5C at Carlow on the 2nd - a joint record with August 1975. It holds the Irish record for most 30C days in a single calendar month with July 2013 (7). 

    It was the driest August on record for many too with near rainless conditions at some isolated stations including 0.4mm at Bunclody (Wexford) all month and for almost all stations. It was also the sunniest August on record with the national record for August set at 283.9 hrs set at Rosslare in 1995. 

    The mean temperature at Phoenix Park (Dublin) of 18.1C was over a full degree warmer than the previous warmest August way back in 1947. 

    It was the literal opposite of August 1912 (coldest, wettest and dullest August on record at the time). We have certainly paid for it since on this island.. with most Augusts (with 2003 and 2010 being the main exceptions for Ireland) being dull, wet and average to mild temperatures.

    Very random predictions.. probably 0% success rate but here we go. 

    January - Relatively mild and changeable. Cooler conditions later on but nothing notable. CET 5.1C

    February - Mild start, cooler end. Much drier than 2020. CET 4.3C

    March - Cold with a lot of cloud and wet to the south of the country. CET 5.6C

    April - Very wet with average temperatures, cool first half before a somewhat milder second half. CET 8.3C

    May - Quite westerly with a fair bit of cloud and rain. Chance of some early warmth later on in the month. CET 10.5C

    June - Fairly dry but often cloudy with mild nights. CET 13.9C

    July - Warm and wet with numerous threats of downpours or storms. Winds from a southeasterly quarter. CET 17.8C

    August - Changeable but nothing dramatic. CET 16.9C

    September - Very warm September with summer heat near the beginning. Turning more autumnal later on but staying mild. CET 15.9C

    October - Another really mild month with mainly unsettled conditions dominant. CET 12.7C 

    November - The mild autumn continues with a typical Atlantic driven November. CET 7.9C

    December - Average temperatures and foggy at times later in the month after an unsettled start. CET 4.6C

    I do hope many of these are wrong especially spring. After the exceptional spring of 2020, I just feel nature will punish us with either a very benign season or a really poor one. Haven't had a really poor one for a while either especially May. 

    May and July the best but the rest very poor and completely off.

  11. An unremarkable summer for my neck of the woods. June 2019 mostly dire and then 'heatwave' was disappointing. July 2019 an ok month but average sunshine so not a standout in my mind. August 2019 I enjoyed because it was my sunniest August since 2010 but mid-month was too changeable and cool to consider it great. Much of September also unremarkable (first week or so) or poor (last 10 days) but mid-month was wonderful with plentiful sunshine and by far my favourite period of the 'summer' even though it was nearing astronomical autumn. 

    I preferred Summer 2010, 2013, 2014, 2018 and now 2021 over 2019.

    Interestingly.... if you combine Junes CET (15.5c) with Julys (17.7c) then the mean for the two months is 16.6c .

    I make that the 5th hottest CET for June and July in the last 100 years...
    1976 = 17.85c
    2006 = 17.8c
    2018 = 17.6c
    1933 = 16.7c
    2021= 16.6c

    What I also found interesting was how whilst the UK tmean for June/July 2021 was the 4th warmest since 1884, it was largely due to minimums and to an extent maximums in Scotland and Northern Ireland too. It was only the 12th warmest for England and 11th warmest for Wales since 1884 in terms of maxima.

    image.thumb.png.c91425c364f59baecd4c9cfe6bf418f2.png

    Perhaps not a surprise at all to those in the south that have found it quite unremarkable in terms of high temperatures since the first half of June.

  13. What I find more odd than anything is how as of this point with the data we have, the highest temperature in the Republic of Ireland from this spell was 31.2C on the 22nd at Durrow. There is still the outside chance there was higher when manual climate station data eventually comes in a few months but I don't recall seeing Northern Ireland beating the Republic in terms of absolute max this high before - June 1989 did achieve 30C in N.I. but not in the Republic.

    Makes me wonder just how limited we are by our current station network of missing out on records. There was a fair amount of haze and high cloud on the 22nd which limited the potential for temperatures to skyrocket more than they did but N.I. achieved 30C on 4 days yet the Republic only did so on 2. The absolute max on the 17th was 29.6C again at Durrow so wasn't far off and makes me suspect that there could have been higher. It took us until the 21st to get the first 30C in the Republic at one of the synoptic stations or the few automatic climate stations. 

  14. Looks like last night may have been another tropical night at Valentia.

    If this was indeed the case, July 2021 is only the second time that two tropical nights have been recorded in Ireland in one month with July 1983 being the other which was a month of a famous Irish heatwave.

    The other mad thing about these tropical nights is the fact they occurred on two consecutive days so the last time Valentia fell below 20.0C was 5 a.m. on the 21st! Phenomenal for Ireland.

    image.thumb.png.b0a4b2cdfb5b8d72ec35103620fb5f03.png

    (The above applies to the Republic, I have no records of tropical nights for Northern Ireland besides the record from July 1868)

  15. A terribly underrated July and summer for Ireland that I hear very few recollections about. July 2006 was my earliest weather memory as we had owned a mobile about half an hour away from where we currently reside in Dublin. I was only 5 years of age but I just about vaguely recall it feeling scorching in that mobile for many days and seeing the pics. 

    It was the last time 30C was achieved in Dublin - in fact 31.0C at Casement on 19 July 2006 is the record high for Dublin for any month. Up until 2018, July 2006 made 2006 my favourite summer I have experienced.

    I have no recollections of June 2006 but statistically, another fine month with the first 9 days in particular being very sunny and pleasant. 

    29 of the days achieved 20C or more at Kilkenny which is an impressive feat for Ireland. 

    A rare occasion where Ireland joined in on the very warm/hot conditions that Europe had which is another reason why I like July 2006. Typically, we're too far west and under low pressure in most of such setups.

  16. Fourth consecutive warm and very sunny day. Best spell of July weather in Ireland since 2013. The weekend just gone was the best weekend I've personally seen. Unbroken sunshine from Friday morning to Sunday evening, and today so far too. Saturday felt tropical with lack of a sea breeze to moderate the warm temps. Usually I'm very exposed to sea breezes during warm spells unless it's a southwesterly which are normally too cloudy anyway to get the most out of so 27C on Saturday was pretty notable and it was still 25C by 8 p.m. I have not known a day where it was so consistently this warm throughout it here.

    Will remember the summer of 2021 very fondly for this spell alone. June wasn't amazing but a good month with a lot of usable weather and fine days. First week or so of July was quite poor but this spell or heatwave right now is something special.
