seeing the steam rising from the garden this morning, could have been in Bangkok or Colombo!

At least we have a cooling breeze here which is preventing the temp from rising beyond 33c

Next week is going to be a huge shock though.  Just as Wimbledon starts, so it will turn wet and cool and the pattern looks locked in for some time

All those who rushed out to buy air con units maybe regretting it!

Doesn't look terribly cool across the south for the next 7 or 8 days at least with temps still in the mid 20s.

A quite ridiculous heat index of 43.4C now with a temp of 36.3.

Wouldn't be so sure about the June record either - Southampton just 0.5C short of it at 2pm. Amazing if it was Southampton that broke it again! If the old Mayflower Park station was still going it might already have done so...

Although actually I just checked and the Southampton site is not an official Met Office one.

It's not even 2 PM GMT yet, there are still 2 or 3 hours of potential heating to go.

Southampton (site ID 99079, which isn't listed on the MetO site but which appears on other lists) is reporting 35.1. 

Almost certainly it's been beaten 36.5C here earlier.. 

Not on the 3pm readings as far as I can see. 35.2 at Southampton, 35.0 at Gosport. Thorney Island has dropped 4 degrees in an hour.

Lots around the 34.5 to 35 mark. Stalled a bit here too, 36.3 and plateaued for half an hour.

So close, where are you seeing these readings please?

Weatherobs.com is a handy place to see the live updates on a map.

Nice one, thank you. 

Chertsey and Wisley are both on the MetO list and showing 34.7 at 2.00 

with 2-3 hours left I would not be so sure the record is that safe

Take for example Gosport fleetlands which was 35C at 3pm. This station is somewhat exposed to the harbor and is away from the built up area of Gosport so it's almost certainly a couple of degrees warmer in the more urban areas of Gosport. Then there is the heavily built up city island of Portsmouth on the other side of the harbor - guaranteed to be 3-4 degrees warmer. 

So the forecast for 37-38C is very much accurate it just down to the scarce official record sites that mean an official temp has yet to be received.

Anyway from past experience with the fleetlands station I'll await until later to see what the met office say as the hourly report can be under sometimes.

Today's temperatures are slightly down on yesterday's values but are still high enough for that in conjunction with yesterday's values to mean that tomorrow's temperatures now only need to either match or beat today's values for the first official heatwave of this year to be recorded here in Edinburgh.

I don't like to blow my own trumpet of course (as a certain YouTuber with the name of Mark Vogan would say) but this has clearly shown that my prediction of 25°C or above for today's maximum which I made earlier on today in the CC thread is much more in line with what happened than your estimate of only 24°C who you had made on that same thread, so that is something which I'm pleased about.

Max dewpoint today was 24.2!
