Minimum yesterday: 18.9


Maximum: 37.3 (!!!)


No mean released, but my maths says 28.1. Hottest day ever by 2.8C!

Mean has also been updated on the website to 28.1C, as you calculated.


 


Is that a record for all three then?

unless anyone is aware of other higher values- I checked 2018,2006,2003, 1995, 1983, 1976, 1975 (3rd I think with 18.5 on 5th)

1975-08-05   18.5

1997-08-11   18.8

2004-08-09   18.5

2006-07-26   18.0

2020-08-12   18.5

2020-08-13   18.0

2022-07-19   18.9

but also....


2016-07-20   19.5

 


 


So July 20 2016 seems to be the record minimum, if that is accurate.

That was a very hot day as well so surprised the CET wasn't a record breaker

Yestrday's provisional CET max was 37.3C and (apart from yesterday's 34.8) beat the previous record max of 34.2 by over 3C


In stats terms that is just about 1 sigma (1 standard deviation) more than the previous outlier (from about 4 to 5)


In terms of return periods that is a huge difference and despite the dire forecasts of climate change I doubt there will be anything to match this CET max for a very long time to come (probably not in many of our lifetimes)


There may well be more regional records broken but the CET covers such a broad swathe of the country

2016 was also notable for hitting 34C in mid September
Arguably just as remarkable as this week's 40C being that late in the year

18.3 CET to 20th.


 


Edit: also interesting that 19th July was the heat peak in 2006 as well.

This month has been quite remarkable locally.


I have not recorded a maximum temperature below 21°C and that temperature was on the first. It was 22.9°C on 5th and every other day has been >23°C. Yesterday was the first day < 25°C since the 7th. There have been 8 days of 27°C or more.The first week had fairly cool nights but the rest have been above average. Highest max however was a (comparatively) modest 33.1°C.

Hopefully, he will just be enjoying a well deserved break and is perfectly OK.


If that is the case, I'm sure that he will be back before too long, all nice and refreshed from that (albeit, with him making fewer of his famous typos as a result).

Another 0.1C would put us in the top 10 Julys, joint 10th with 1757 and 1808. A 0.2C increase would tie us with 1976 (don't tell GB News!)


I see that since the Hadley figures were revised, July 2006 has gone up to 19.8C. It used to be 19.7C.
