Temperatures are soaring in some parts of the country now and over the next few days those temps are not only going to spread to other parts of the country but they're going to be climbing too. For the record please post your high temps here from your own personal station and any official station nearby. Don't forget night time temps too!

Today in Torquay we had hit 20C by 7:30 am. 27C by 9am and 27.2C at 10:40am. The MAX recorded was 29.1C at 3:40pm. A few of the personal weather stations near me recorded 30+ but none of the nearby stations reported anything lower than 25C and most had maxes of 26/27C+. Its hard not having an official station nearby but there's no doubt today we recorded temperatures in the high 20's! Now lets see what we can get on Monday and Tuesday.

I suppose it wasn't just the heat that made me ask about night temps but I'm interested for the reason that you mention that we have some oddly low one's recently. Its been down to 12C here too and that's not normal we can get that in the winter usually during an Atlantic storm. But still it will be interesting to see how much daytime heat we can build and then how quickly or slowly it cools down.

27C out there right now, which is unusually warm for here - the westerly breeze is cancelling out the sea breeze that would have otherwise brought relief. Later this week there will be a sea breeze, but just look at that minimum on Wednesday morning! I suspect I'll be going to work in a school filled with sleep-deprived zombies on Wednesday if that comes off...

(The all-time record "max min" is 23C in London IIRC.)

on a nighttime I'm thinking southern & southwestern coastlines will be slow to cool, and perhaps also some East and southeast coastlines if the wind is blowing from the land, and in and around London.

Midland and northern towns will have a sharp up then down.. 

Any place that either isn't a) on the coast, or b) at the centre of a major city, will have big ups and downs. Like on 1 July last year - the min temp in the morning here was 15C, then it rose rapidly to 33C, and then fell to 18C the following morning. 

It's quite hard for us to stay very warm all night, under clear skies. During hot weather it's quite normal for it to be around 21C at midnight but it will continue to fall away rather fast. During the one-day heatwave last year it was 23C at midnight, 22C at 1am, 20C at 2am, 19C at 3am etc. 

I'm 15 miles inland and just out of town (not a major city); after 20 years of records, 1/7/2015 smashed the overnight low record with 23C. We thought the weather station had broken. But, you see, with very warm uppers, those other factors become less primary.

Maxed at 24.4c here today. 

They didn't mind you getting that close for a picture? 

For the record, the average July minimum for southern England is 12.0c (81-10) - so the idea that such temps are cool is for the most part erroneous.

Obviously some parts will have a higher ave min, but some parts of the south will have a lower ave.   As will places further north.

err maybe the average for some country village stuck out on the downs surrounded by forest - but for most of urban southern England it is much higher.
