Some of the longest heatwaves on record in the UK June/Jul 1976: Cambridge 17 days Aug 1997: Cavendish 16 days July 2006: Cambridge 14 days July 1983: Liphook 14 days Aug 1975: Leeming 14 days Aug 2003: Kew Gardens 13 days

Comparing the UK heatwaves of June 1976 and June 2026... Daytime maximum & night minimum temperatures were much hotter in 2026. Details: maxima over 21st-30th June in both years. Uses provisional 2026 HadUK-Grid data from Met Office NCIC. Note the difference scale is larger for night minimums.

Last stat update... The UK is running on 9 tropical nights to date for 2026 to June 30th. This is the equal 7th most since 1940 but bear in mind this is only from May and June which is exceptional. Tropical nights are most likely to occur in July and August.

As of June 30th, the UK has seen 15 days of 30C+ in 2026 so far. This is the 10th highest on record since 1945 and is still the highest running of any season to date to June 30th. The record years of 1995 and 2018 weren't even on 10 by this point.

14/25 Irish synoptic stations broke or equalled their June max temp records in the recent heatwave. 6/25 stations broke their records for any month though most of them have short term recording history with the exceptions of Claremorris and Markree Castle.

This is where the recent Athenry 32.2C on 25th June 2026 stands within Ireland's warmest days on record. It was the equal 5th warmest day and highest June temperature since 1976 in Ireland. *Converted from whole Fahrenheit.

One of the single greatest nights of my life this night last year. There's a reason it's been my profile pic for this long. Noctilucent clouds shining in all their glory in Dublin Bay with perfect clear skies, reflections and warm for t-shirt/shorts. Perfect summer night.

Another Poolbeg moonrise to add to the collection. When in Clontarf, you can't not do this comp as well.

Moonrise aligned with Our Lady Star of the Sea from Dollymount Strand this evening.

June 2026 CET now standing at 17.1C to the 26th. The last time there was a June mean as warm as this in Central England was 180 years ago back in 1846. It won't get to the dizzy heights of 1846 (a ridiculous 18.2C) but will it rise a little more or stick around 17.1C?

We are up to 12 UK all-time maximum date records being broken so far this year - 1 in March, 2 in April, 5 in May and 4 in June. The symmetry between the May and June heatwaves is definitely interesting - the date record on Wednesday was broken by a margin of +3.5°C!

UNPRECEDENTED ❗ The daily CET for 26th June 2026 was 26.5C. This is the second highest of ANY daily CET mean on record since 1659. Only 19 July 2022 (when 40.3C was achieved) was higher and is 1.2C above 3rd place (25th July 2019). This beats the previous June record from 19th June 2005 by 3.3C!

Seen a query yesterday asking if there's a record for how many days the UK monthly maximum temp record has been set in a row. From what I can see (though could be wrong), June 2026 did so with 3 consecutive days. Before this February 2019 did it over 2 consecutive days.

A grand total of at least 130 UK stations broke their June record for high maximum temp with at least 30 years of records. At least 124 broke their June record for high minimum temp with at least 30 years of records.

The June 2026 heatwave stands out in the Irish record for being short but intense. The previous times 32C occurred tended to be with heatwaves of at least 7 days in duration whereas June 2026 was only 5.

26.2C at Valentia at 0830.. Ireland..

Possibly a tropical night at Glengarriff. 09-06 hourly min was 20.5C (and I presume it won't drop by 09!). Showed all the previous tropical nights on record below in Ireland which there aren't many, last ones in July 2021.

Today saw a provisional new UK June temperature record of 36.1°C in Gosport. (Note that not all official weather stations report live. One of the ‘slow’ manual reporting stations might be higher when data arrives tomorrow morning.) Temperatures look set to go higher again on Thursday.

We are not done yet! New figures gives a new provisional June record of 36.1 °C in Gosport

This excellent graphic on istheukhotrightnow.com really shows how extraordinary the 35.0°C at 3 pm BST at Bournemouth Airport is. In records back to 1970 for a 7-day window around 24th June, only 1976 gets within 5°C.

Provisionally, today is now the warmest June day on record in the UK, with 35.8 °C recorded at Wiggonholt, West Sussex

As of June 24th, 2026 is on 12 days with 30C or more in the UK. This is the joint 15th most since 1945 for the season as a whole. As of June 24th, it's by far and away the most on record. The record years of 1995 and 2018 didn't even have a single 30C day as of this point.

2026 is already on 4 tropical nights in the UK. At least another 2-3 probable by the end of the week? 2023 had 4. 2022 had as much as 10, the third joint highest on record.

It's not often we see "tropical night" (daily 09-09 min temp at or above 20C) conditions this widespread across England, it's usually just a couple of stations.

This decade alone, Dublin Apt has set monthly max temp records for April (equal with 2019), May, June, July, September and October.

A record warm June day here. Dublin Airport had a max of 27.0C at 3pm. Previous June record was 26.5C on 27th June 2018. Records since 1942.

Happy birthday to the heatwave of 1976 which began today 50 years ago, peaking at 35.9°C. If a comparable heatwave happened in the current climate it would be 3-4°C hotter, peaking at 38-39°C. And the actual forecast is for temperatures of 38-39°C in the next few days with a red heatwave warning.

June's record was already beaten in May at Kew Gardens, and it looks to be beaten once again by a margin of potentially over 4ºC based on the Met Office forecast. There is simply nothing else in the historical record at Kew that compares to records being broken like this.

I've just come from an event this morning where a forecast was presented for how a heatwave in 2056 would look. A 9-day run of over 40C. Peak 45C. Middle Eastern temperatures in the UK. And today we already see the impact that a heatwave in our current, cooler climate has on our lives.

UK red weather warning appendix updated to include the latest one for June 2026.

The only times Ireland has had 30C in back to back months were June/July 1976 (same overlapping spell) and July/August 2022 (two different spells). May/June 2026 will be another. June and August 1995 had 30C but separated by 28C in July.

If nothing else, most insane temperature chart I've ever seen projected for Ireland. Will it verify? No. Ireland's temp record is 33.3C all the way from 1887. Could you imagine the anomaly 36/37C would produce? Not sure what the f- ARPEGE is on.

Beautiful moonset aligned with Samuel Beckett Bridge last night.

Weather forecasting is an extraordinary achievement. Without it, on this cool, heavily overcast morning in NE Dorset, I’d never guess that a record-challenging heatwave was on the way next week.

Difficult to tell if any Irish station will achieve heatwave criteria (5 consecutive days >25C) this coming week, it will be close if it does. Reminder of all previous Irish heatwaves on record. The last one was September 2023. No, May 2026 and July 2025 were not Irish heatwaves.
