There are two varieties of CETCET Central England Temperature data which you can download from the UKMOUKMO The Meteorological Office is the United Kingdom's national weather service. It is an executive agency and trading fund of the Department for Business, Energy and Industrial Strategy, they are the monthly series from 1659, the daily series from 1772 for daily mean temperatures, or the daily maximum and minimum series from 1878. So if you want monthly means in central England, you are either stuck with using ‘meteorological’ seasons by adding up three monthly means to get a seasonal mean, or alternatively adding up 90 or so daily values, and calculating either a meteorological or an astronomical seasonal mean. And that’s what I’ve done with this bespoke viewer which allows you to view any season, be it astronomical, or meteorological, for any year since 1772. It’s a big improvement on using monthly data, because as well as looking at meteorological seasons, I can now view astronomical seasonal means, as well as the latest three months of daily data, or see how the latest season is doing. By the way, you are now deep in weather nerdland with this article. 😜
