Impressive heat here with a maximum temperature of 29.3c. No surprise really though with crystal clear skies, lack of breeze, 850Hpa temps approaching 20c and 573dam air present.

31.0C was the official max for Heathrow. Can't find the exact figure for Cambridge yet.

---

31.6c on St Helier on Jersey looks to be the max.  Highest on the mainland looks to be 31c at Heathrow, but not confirmed

---

OT but I've never understood why the Channel Islands get included in the UK stats. They're no more part of the UK than Gibraltar, and we don't include that!

---

Just looking like a one day event here. 27C this afternoon, but looking like being only 23-24C tomorrow, but of course I may be surprised.

---

maxed at 27.3c today, very humid feel to the day....

---

Managed an impressive 28.7c here.  A great late August mini heatwave

Edit - Arpege has the +20 850Hpa temps oozing into Kent 1pm tomorrow (BST): Clearly 34c or 35c is entirely possible somewhere in the SE corner, Norwich could do well.

---

For a small nation we certainly have vast day to day differences in the weather. Today at 6pm for instance, London was sunny and 30 C, Edinburgh was 16 C with light rain.
No sunshine today up here either, quite gloomy.

---

Temperatures really ramp up today, with 40C possible somewhere in South West France. Various cities have forecasts of 35C+ every day between now and Sunday, and France will be almost cloudless in that period. It's a shame the shape of the double ridge is keeping most of the heat to the far South East of England the next couple of days, as it's always nicer to have a nationwide event. It also means more cloud even in the SE than would be ideal. We're on the edge of the real heat.

For the pedants out there, Meteo France has a formal definition of "canicule" - which is close to what we'd describe as "dangerous heatwave" - but uses the term "vague de chaleur" which is the literal translation of heatwave more loosely. For example the local news in Saone et Loire describes this week as a "vague de chaleur durable" which won't quite meet the canicule definition because of relatively cool nights below 20C.

---

Surprising to see Met Office sticking with 31c as the Weds max when 34c seems to me more likely, possibly more.

---

 

Hmmm - there are strands of high cloud draping across the region though. Outliers from the frontal zone further west, which may come and go today and knock a degree or so off. I'd be surprised to see 34c - just feels a bit late in the year. That said, it was already approaching the mid-twenties by the time I got into Central London this morning at 0845, and there's less of a breeze than yesterday, so you never know. A 32c certainly seems likely.

This has actually turned out to be a fairly decent second half of the summer in this part of the country.

---

It's set to be the first summer for many years when every month has been warmer than average, and significantly so.

Heatwave wise though not so much. Until this week we only had one short spell that hit 30C somewhere in the country and that's under par. This week probably takes us up to par. There was also that week in early summer where fortunes reversed and we had beautiful weather in the north west and overcast muck in the SE.

Today is the peak for London this week. More cloud to come tomorrow. I'd hazard a guess that we get to 32.5 today, with Gravesend the top spot.

---

Although at 1030 am, Manston already showing 28C!!!

 

Bit of an outlier, but not much. The usual suspects creeping towards 27C

---

Ive noticed Manston (and sometimes Langdon bay) gets very early maxes during heatwaves. Must be its location. I would guess it'll flatten out around 30 and others will then overtake it.

Feeling like 28C now in Canary Wharf

---

 

Our 'heatwave' this week was yesterday (around 25c) and I was lucky enough for yesterday to be one of my childminding days off. LUcky me.

Fresher today (max forecast at 21c), then sub-70f temps for the foreseeable after that.

Summer is over.

---

 

Time to start watching the snow row then?

Hot down here. Damned hot.

---

Definitely hottest in the far SE. Manston already 27.5C at 10am.

---

The thermometer reads 30.8C in the shade...

---

Yes got 30c here in Hampshire. Forecast yesterday much cloudier, with a high of 24c and much cloudier! ...not a cloud in sky here!...abysmal when the can't get it right 12 hrs in advance

Just got to 30.0c here @1pm

---

Sizzling in Central London. Feels beyond 30c already I guess so with a few hours to go, maybe that 34c not so crazy after all... My
money's still on 33c though.

---

May have just maxed at 28.3 with sea breeze now kicking in.

---

Blowtorch heat here today with 30.6C already reached. 

---

Temp has fallen by a degree in the last 30-40 minutes to 29.5C, maybe it's that breeze.

---

33.1c here.
