Further west it was a cloudy first thing which then cleared but there is now a lot of, albeit thin, cloud. It is very warm and feels humid - unfortunately I can't give any figures as my weather station is not working at the moment.

Was a large'ish area of ppn that's been moving ENE from about mid-Wales. It's now over Pennine areas/West Yorks, but the radar echoes look lighter so not sure how much is actually falling.

For a time MBY was under reds. Pretty much zero wind so the rain was falling vertically and uniformly.

Clouds have been thinning since and we've had decreasingly hazy sun for the last hour.

The rain's just given everywhere a watering and freshening - and at a time that doesn't make a real difference.

Sometimes it seems like you live in a different country from the rest of us 

Yes that's the guy I got the stat off, he's very good. 

I agree 34 looks virtually impossible to achieve.  20 though looks likely atm.

Midday 29.8c

Herstmonceaux 31.5c at noon. Highest so far 

Just hit 30c, so second day in a row for this heatwave

Edinburgh can join the party.....26 C at 1300!

Blessed 1995 was the most in my memory for really good summer had 35c on 30th June under gin clear skies then many days over 30C in July with mid month had several days at 33 to 35 and 20 to 21 at nights which reached 15 times. My mom change my pillow every 2 days due to sweat and had no fans at home.  Had a nice relief cooler break mid month to 25C and 7C before resuming hot weather to August.  🥰🥰

Currently dirty blue skies and few horrible clouds around.  🥱

You need to get back down to Epsom Jiries. 

Most weather stations in Jiries’ region seem to be reading in the range of 29 to 31°C just now so a hot day there.

31 degrees here in Fulham with hazy unbroken sunshine don’t think it will get to 33/34 as projected 

Now 27.1°C at Edinburgh Gogarbank which makes today our hottest day of this month so far by quite a bit, and is only 1.7°C below our highest temperature of the year so far which was set back in June.

Yes went to the shop now and was greeted with welcome easterly breeze cleaning the muck but as a time keeper is too late to savage today so hope tomorrow see direct sunshine from dawn to deliver a heatwave.

Frustratingly it's hit 29.9C several times today at the vineyard but hasn't yet tipped over (and it's East facing so tends to peak early).

38.8C on the PWS at our place in France. A whole other level.

Well, it's certainly what I'd call a heatwave here. 31.1C.

Taking inspiration from his thread, I think it would be worth doing the stats (if at all available - I'm not sure how or where) for a new measure I'll call heatwave degree days. That is, cumulative degrees at or over 30 (where 30 = 1 HDD, 31 = 2). That gives us a measure of both frequency and intensity.

I calculate the 1995 HDD based on his 32 days as 99.2. That implies the "average" of those 30+ days was around 32C. You could get 99.2 HDDs with 99 days of 30C, 50 days of 31C, 33 days of 32C, 25 days of 33C, 20 days of 34C or 17 days of 35C.

Anyone know where we can get those daily maxes for other years?

Occasional poster Kev Bradshaw (he of the Manchester Winter and Summer Indexes) is a brilliant source of these kind of stats.

Always feels like he only posts on TWO in patches, though

I so know that frustrating 29.9 Tim- first had it on 1st August 2013 (shows how pained I was that I can remember) and on numerous occasions since. I wonder if auto stations need extra enery to change all 3 digits on the scale. In the 'old' days (80s and 90s) they'd have just said 'fi' and read it as 30.

I don’t think he has posted for quite a while. That said, for the avoidance of doubt, he is always very welcome here.

Interesting idea; although I feel heatwave impact on daily life includes sleepability so min temps and humidity would surely be relevant.

It finally managed 30.1C, so the pressure is off.

France seems to have topped out at 39.5C though. Hottest I've recorded but tantalisingly close to the big 4-0.

Currently 32.2c here

28.1 C in Edinburgh. 2nd hottest day of the year!! Heatwave level exceeded, what happens on the next 2 days 🤔

Frustratingly I only made it to 24.5°C today so no three day heatwave threshold for me. It has however still been very pleasantly warm.
