Oxford’s hottest day this early on in the year (in the past 50 years)
It was a bit hot last week wasn't t it? Might be too hot, even. If you’re currently in the UK you will know exactly what I mean, and if you aren’t in the UK - well I’m sure you can imagine it. Just think 31 degrees with a disproportionate amount of moaning.
This week we will be taking a look at some historical temperature data. If you’ve wondered how hot it usually is at this time of year, or how many days there have been in the past which have been hotter, then read on!
(And a disclaimer for any actual climate scientists reading this: most of the calculations I did for this are very back-of-an-envelope, so don’t take them too seriously!)
This plot shows 50 years’ worth of historical temperature data, recorded in Oxford. Each grey dot is an individual day in that 50 year time period. Three days last week (Wednesday, Thursday and Friday) are represented by the larger red dots. We can see that all three days are much hotter than average, with Fridays’s dot being on the very edges of the historical distribution. In fact, if you count up all the days that have been hotter than today, there are only 70 in total. However, all those 70 days occurred later on in the year than 17th June, which means that today marks the hottest day this early on in the year that Oxford has experienced in the last 50 years!
