28.1c at Kew is the highest so far I can see. 

28.5c in St James's Park we are getting close but probably won't quite get there today. Tomorrow looks almost certain. We could get four 30c + days in a row from tmrw

St James's Park has reached 28.5 and I suspect there is a bit of heating to come after the 4pm reading.

Indeed some stations have even risen again at the 8pm reading (after an earlier dip).

29.3C at St James's Park looks to be the highest, so not quite the warmest day of the year (and tying the mark set as long ago as 1st May!)

25C here as I put my thermometer out so very likely to reach 30C today and a bit over 30 too as well.

Who went for today? Looks certain 

I did A-P.

However I'm quite happy for Brian to give the prize to someone else if he sees fit as today wasn't my first guess - it's actually my third!  

Brian had said further back in the thread that if your guess had passed unsuccessfully then you could try again so I did - twice 🤣

As they say - third time lucky.

I don't want to be seen to be taking the proverbial though so I'm happy for the prize to go to the next closest person.

Take the glory SD.  😁

Exactly. If nobody else got there first then why not take the prize.

.

And there it is. 1pm update has St James's Park at 30.1C.

I demand a recount.🤣🤣

Plenty more time as well 33c on the cards.

Spare a thought for the Baltic and Scandinavia - nothing above 21C and mostly 17s and 18s at midday. N Scotland, too

29.3C here at 14.10.

31.3C at Heathrow at 3pm, 32.x or possibly even 33 looks likely.

I declare a winner! 🏆

Maxed here at 31.5C at 15.36 . Some slight cumulus bubbling up now and again and pegging it back.

Wales has also breached 30C today with 30.1C at Cardiff Bute Park so far.

Woohoo!

Thanks Brian - that's brilliant. 

I've sent you a feedback form.

👍I've just replied to your email.

Nice prize Brian 👍🏻

Official high today was 32.2C at both Heathrow and Kew Gardens according to the Met Office. A gnat’s whisker under 90F in old money. 

Congratulations!

Four days out for me. Looks like I got the location right though 😂.

Well done Dave. That's a nice prize off Brian. I suppose it's also a thanks for running the CET competition too!

Looks like a few places over quite a large area have nudged 30c today. Heathrow at 30.8c is the highest I can see so far
