Another astonishing statistic about this heatwave: before 2026, the earliest in the year 35C was exceeded was 26th June 1976. This time it has happened a full month earlier!

I wonder what summer 2026 has in store?

Probably the most significant stat of the whole heatwave.

A game changer.

The answer is, of course, to adapt as best we can and prepare for what lies ahead - you'll note the piece I posted about aircon being required in all schools within 25 years, and all hospitals within 10 years. It will become normal in homes, too. Similarly flood defenses will need to be improved, and a wholesale redesign of new houses will be required in the decades to come. 

The BBC has a podcast about "climate anxiety", as it's called:

This year's event is just another reminder of how the bell curve has shifted right, and the spikiness it causes in warming in general as it does so. I also wouldn't be at all surprised if summer proper ends up being what most people would call mediocre, it's very rare to get two historic heatwaves in one year!

As to taking action? It's never too late, or rather, inaction is to just give up. Humans don't tend to do that.

I suspect if we don't stop it, it wont stop. Then even you will be cooked 🙂

Can't agree with that one I'm afraid. I defy that anybody enjoys 40C - even Indian and Pakistani cricketers! It's also a killer for Northern Europeans, especially if they are elderly or have certain conditions like my wife who doesn't produce sweat and overheats quickly and gets ill. Any normal person should feel that 25C on a sunny day is more than hot enough! To me it's a bit like saying I like windy weather so lets hope we get more killer tornadoes. But I do agree we need to adapt and take measures to accommodate it. But that shouldn't be at the expense of acting to slow it down for future generations. It is becoming exponential now but we should strive to mitigate the rate in the future with targets like net zero, not for us, but for our future generations. Remember we don't actually know what it will be like if we don't eventually attenuate it - unless you like the idea of living on Venus!

24.3C here at 10.30pm. By far and away the hottest most humid night so far. This in part from a late afternoon sudden injection of heat taking the temperature from 28C at 4.00pm to 30.2C at 6.00pm for a much later max than the rest of this heatwave. And that was with a cloudy sky as well - what happened there?! So I could be getting a record May high minimum here tonight I think.

It's still 18.6 now, the blanket of cloud effectively trapping yesterday's stale heat. I note, wryly, that the band of rain that crossed the area overnight managed to break up over Sheppey, only to reform a few miles to the east. Sod's law! Some of the cracks in the lawn are an inch wide now...

Another very hot day on the way today (28 on the MetO raw, remember the average is 19 this time of year), a very warm weekend and then, finally, at long last, a run of near-average days early next week as the return of the westerlies / Euro monsoon sets in.

Here in Edinburgh, last night was the joint warmest May night on record at the botanic gardens according to records going back to 1959, with an overnight minimum temperature of 14.1°C. That record was set on 25 May 2017 and in addition to that, a new date record for there was also set as a result as the previous date record for there was 13.9°C as set in 2001.

For some reason the Iver Waterworks high of 32.1 isn't appearing on the list. Perhaps some issue with it? There was a missing reading at 1300Z but the 1800Z reading shows a max of 305.26K, which is higher than the Heathrow max of 305.15K:

I don't agree with the attitude that we can't do anything about it and it's up to Governments. We can do our small bits and vote for Governments that will do more.

Public pressure works.  My feeling is this hot spell has made a lot of the public think. 

The cesspit that is social media is doing it's best to counter that, but more heat will be along at some point - denial is just going to get more and more difficult and the bots are going to have to be reprogrammed to find new lines of attack..

I think this hot spell has changed things here on TWO too tbh. I (and others who have been concerned, worried even, for decades) used to get a lot of flak - not any more.
