May in central England

May 1772-2020 CET

May is an unusual month in central England in the fact that mean temperatures for the month have hardly changed in almost 250 years. The linear trend since 1772 reveals that May has been warming at the rate of 0.01°C per decade. The coldest May in living memory occurred as recently as 1996 with a mean of 9.15°C, the anomaly of -2.02°C rivals any of the cold May’s that occurred in the late 18th or 19th century. We are long overdue a cold May there have only been five cold May’s in the last 20 years or more, maybe 2021 will make it six.
