Apologies if this is in the wrong place. If it isn't then feel free to create your own to add to the thread!

I created this wikipedia-style climate box for Heathrow's average annual temperatures, precipitation (+rain days), and sunshine hours for the last 30 years.  It gives an idea of what the 1991-2020 averages may look like. There's an almost blanket 0.4c warming of mean temps, with a slight increase in precipitation and a slight decrease in sunshine hours.

Mean temp / precip / sunshine difference vs 81-10 normals
Jan: +0.4c / 108% / 95%
Feb: +0.5c / 110% / 98%
Mar: +0.4c / 91% / 104%
Apr: +0.5c / 100% / 100%
May: +0.6c / 91% / 101%
Jun: +0.4c / 100% / 97%
Jul: +0.4c / 101% / 100%
Aug: +0.2c / 108% / 96%
Sep: +0.3c / 98% / 100%
Oct: +0.4c / 89% / 98%
Nov: +0.4c / 108% / 98%
