Winter 2020 was the 10th warmest winter since 1659 in Central England. The mean temperature was 6.16°C which was +2.24°C above the 1772-2019 long-term average. Rather underwhelmingly it was the warmest winter since 2015-16, but it does add another 21st century winter to make it five in the the top twenty. There were no cold spells to speak of in the three months, which was dominated quite depressingly by a series of long mild spells. No day records were broken either for warmth or for cold.
Winters continue to warm since 1878 by around 0.08°C per decade.
