Does anyone know if there's a site recording numbers of 30C+ days each summer (or each year) anywhere?
I found a chart on this blog page: https://wansteadmeteo.com/2022/05/10/30-degree-season/
but that only refers to London (it shows 13 days for 1976 and I'm sure there were more than that UK-wide - I think 15 days beat 32C somewhere didn't they?). The highest total on there is 14 for 2018.
I’m not sure there is anywhere that lists number of 30C days for the country as a whole - only ones I’ve seen are per station eg Heathrow.
The coming heatwave now looks firmed up. Possibly the last of the summer, but at least akin to the July 2021 spell and possibly the extremely hot week of August 2020. This morning’s GFS op:
25,28,29,31,33,34,36,36,33,32,33,31,30,27,27,23
10 days above 30. 4 more above 80F. Only one day below the old red BBC temperature badge level and that’s at the end of the run. I remember when the red circle was a sign of exciting summer weather.
