No (just abouts). Closest attempts are June 2016 (101.7 hrs), August 1958 (103.1 hrs) and August 2008 (104.3 hrs).

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.

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.

2014 max was 90f (32.3C) on 18 July, not 34C. 2013 did reach 34C on 1 August.

Since 1960 (may have missed 1 or a few days in some earlier years). The 1960-2020 average is 6.8 days.

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.

I'd largely say the same list of 'good' summers for Ireland except remove 1994 which was terrible here as we were too far west to tap into the fine weather (typical) and add 1968 which was very sunny with drought in this country - I know England had a very different story, sort of similar to 2021 in a way but 1968 was a different kettle of fish.

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

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.

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. 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.

The Armagh 31.4C did not pass quality checks so the Castlederg 31.3C is the new official Northern Ireland record although I hold some skepticism with the tarmac around the station.

Some stations have had 10 consecutive days of heatwave conditions (25C+) which makes it the longest heatwave in mid-summer since 1995! The 2013 heatwave (from a statistical standpoint) lasted from 8-12 July generally. The 2018 heatwave was more early summer as it began in June.

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.

1989 was most certainly not poor.. 1990 too to an extent.

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

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.

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.

Second best display of the season I had seen last night in Dublin. Had just rushed out to my local park last minute so not great images.

This month holds the record highest monthly sunshine total for various stations in Ireland as well as the national record of 308.2 hrs which was strangely at Valentia Observatory - a station normally prone to cloud and exposed to southwesterlies so a weird quirk but is indicative of how unique of a month July 1955 really was. Dublin Airport wasn't far off with 305.9 hrs, May 2020 was the closest competitor to this with 295.0 hrs. June 1957 and June 1959 were also exceptionally sunny; 292.7 hrs at Belmullet (northwest Ireland) and 301.0 hrs at Rosslare (sunny southeast) in the respective Junes. Yes a long time ago but July 1955 and August 1947 are terribly forgotten if you ask me, both gems of summer months in vintage years for weather too.

Sounds like last summer here in a nutshell. People thought I was mad in hoping for winter because I wouldn't have to look at 16-17 hours of cloud with the shorter daylight. This one 'til now has been distinctly average in Dublin in terms of sunshine, nothing like last year nor amazing like 2018.

Lidars look good for tonight if you manage clear spells. No chance here with the cloud coming from the west (already has come).

NLCs visible from Howth tonight.

Could see it for a time at Sutton before the mid level cloud went and 'ate' it. Had a bit of kelvin helmholtz too illuminated by the limited visible NLC (not that noticeable in this longer exposure). Nothing like Friday night's display. Pics at the Malahide Estuary.

Yeah, as a poster mentioned, still on only 0.8mm here this June so far (which is drier than June 2018) in Dublin and there wasn't any rain this morning again. The low pressure has been displaced further southward than models have expected. Some rain possible mid-week but not of great amounts to ease the moisture deficits that are on the rise. It's fortunate May was wet as a much drier May combined with the dry April and dry June so far (also a relatively dry March) would have been very bad news. Funny how the SE of England has been having a deluge whilst it's been some of the nicest days all month here. Temperatures have been cool but the strong June sun makes it pleasant. The first half wasn't very dull but often a fair amount of cloud and quite humid after first few days which I did not really like.

The nation's max temp from the July heatwave was 26.6C on the 22nd when the wind was initially southwest. The max on the 25th was 25.0C. Ireland is too far west to be directly impacted by southerly flows as low pressure sets up shop close to us. We need an easterly tilt to the wind. Years that 30C was achieved: 2018, 2016, 2013, 2006, 2005, 2003, 1995, 1990, 1989, 1983, 1976, 1975. To keep on topic with this thread, personally I have not found it to be a bad or great June so far. Almost bone dry, not cold and often humid but not a lot of sunshine. Distinctly forgettable and boring.
