If you had said that 30 years ago you would be thought to be mad

Rounded 28C in a couple of places. I’ve not checked actual maxes yet.

29.5C down here.. officially I don't know but I suspect Gosport fleetlands will have exceeded 28C and it's an official station.

27.5 Heathrow looks like it. 27.4 at Thorney Island. 

He's been saying we won't have a summer at all because of El Nina, yet June was pretty decent and now a decent chunk of July is looking good.

Gosport fleetlands will definitely have been warmer. A private Gosport weather stations I check in on had a temperature of 28.5C, however I'm not sure where in Gosport it is located unlike the fleetlands which is located on the north east coast of Gosport. 

There may have been an other station that the metoffice have that could even be the UK hotspot.

 Gosport fleetlands & Heathrow both tied the UK hotspot at 27.5C then.

This time next Sunday when we wake up to already in the 30's temps with record to be broken somewhere.

Hope you enjoy your holiday in Greece then!

You'll be very disappointed if you're expecting 30C at 7 AM here... even the hottest runs over the past few days have failed to achieve that.

No i mean those who get up at 9am or later as is a weekend day would see temps already in the 30's.  7am likely lows 20's after high teens over night temps. The following night might be record to break the 24C minimum somewhere.  Earliest 30C I recorded was 9.30am on 10th August 2003 then 38.6C by 5pm. 

If the dewpoints are as low as they are being predicted I would have thought overnight minimum temperatures wouldn't be too high ?

Indeed. Big UHI effect too when it’s dry because land use has a bigger influence than humidity on keeping temperatures up. It was 8.1C at my vineyard last night, and 16.7C at the nearest PWS to us in London. 

I thought there was an indoor temperature thread.

What makes a thread "official"?

Posting for posterity before it changes. These weatheronline sequences are usually on the optimistic side but still fun to see a 45 on a forecast:

Madness. 47c for Paris too. 

If they start appearing on Weather Apps the hype will build even further amongst the general public. 

Just eyeballing the data, and if anything, a neutral to negative Nino index favours hot sunny summers:

Which of course is more than likely just noise, but enough noise to knock the claim that La-Nina = bad summers out of the water. 

A lovely morning here, after some early cloud. Today will probably be the first day of the heat wave here, though not quite "heat wave" temperatures yet. It's funny that until now, we've been stuck in the upper teens whilst the SE has had upper-20s... a common theme this summer so far.

BBC now have 34c on Sunday for Heathrow.  I can see this slowly ticking up through the week.

BBC now has 37c on Sunday for Heathrow. Getting there!
