I do hope this heatwave is not a That All Folks! for this year.  I need now to see June to update their outdated hottest record and it becoming embarrassing that June the month with longest day light, current global warming did not break any records yet.  It time to see at least 38C 100F or over to be reach.  Since May now donw at 35.1c then June need to do some hard work to go over it plus July and August.

Why? It's uncomfortable. Records aside (which can be exciting) it's not great, or a great sign, to be launching into temperatures like this so early. I'm only thankful that school aged children haven't been forced to stare at interactive whiteboards all day in this heat due to half term.

I think it's a ME thing Bertie... EOS

I think Whitechurch just pipped it, 31.8C vs 31.6C in Yeovilton.

Incidentally that is now seven new date records set this year, and one equalled:

March 3rd, 18.2C at Wiggonholt (old record 17.8, Manston 1938)

= March 5th, 19.2C at Northolt (equals record from Huntly 1961)

April 7th, 25.6C at Llanfairfechan* (old record 23.6, Oxford 1859)

April 8th, 26.6C at Kew Gardens (old record 24.4, Brixton 1894)

May 24th, 32.3C at Kew Gardens (old record 32.2, Camden Square 1922)

May 25th, 34.8C at Kew Gardens (old record 31.7, Farnham/Heathrow 1953)

May 26th, 35.1C at Kew Gardens (old record 29.5, Inverailort 2012)

May 27th, 31.8C at Whitechurch, TBC (old record 31.4, Gravesend/Herne Bay 2005)

*TORRO lists this but says it is a non-Met Office site, Mona was 24.8C, still a record

Tomorrow's date record is 30.6 (set in 1944 at multiple stations) so a decent chance of five in a row: the Met are going for 31 in the SE.

Would be interesting to know what that old Camden Square weather station would have read in this spell, if it was still there. It features heavily on the date record list!

 Is there an issue?

Guernsey airport low of 22.8C

Jersey St Helier low of 22.6

Jersey airport low of 21C

It is funny how you acclimatise to heat though. A 24°C day last week would have felt very warm, especially given the cooler start to May we've had, but after Monday and Tuesday's heat, it feels noticeably fresher.

An upstream problem means UKV runs from15Z onwards are either not available or degraded.

CMC GEM 12Z I'm less sure about, but as with the UK Met, I don't think the problem is at our end.

Heathrow has got to 30.1c

Think we'll make the date record 

30.4c

Kew has gone walkabout though not ideal.  

It's back but its not great it disappears every so often. 

Think 90f is on the cards today the sweet spot just happens to be West London today normally the hottest part of the country anyway. 

Dipped a bit here with the cloud and breeze, 28C from a high of 30.

Edit: 31.5C at Iver Waterworks.

Rob McElwee just said it was 32 at Heathrow.

The highest May temperature I have had here in 27 years was 27 (moved after the great 1998). 

This year since 22nd it has been (rounded) 26, 28, 30, 31, 31, 30 28. 

I remember being flabbergasted by a week of 22+ in late April 2011. This knocks that skittle over.

I wonder what summer 2026 has in store?

Probably the most significant stat of the whole heatwave.

A game changer.
