After the wettest February on record, the UK followed it with an extremely normal (and boring) weather in March 2020.
The meteorological year starts in December which is why December appears as the 1st data point in the charts below. More information on the layout of the charts can be found in this post. Points lying between the upper and lower deciles are shown as open black circles, points lying between the deciles and minimum/maximum are shown as solid black circles and any month with a new record is shown as solid black squares.
As I explained in October 2018, the addition of a Temperature Range chart (B) means I update 7 charts every month so I rotate which 6 appear in the deck above and 
plot the 7th as a separate chart here. Since it is Winter, Sunshine (chart G) is shown here since that is of least interest in these months.
How abnormal was March 2020?
Chart H displays my UK Weather Abnormality Index (Scroll down my May 2019 post for details). The closer to zero this 
index is, the less abnormal and thus more “average” a month is. The higher it is, the more abnormal the month is. When the index is over 100%, we can describe the month as unusual in some way.
The abnormality index was 26% in March 2020 which is the 4th lowest on record. Nearly every variable was more or less bang on the median with only number of frost days getting close to being unusual.
