April 2026 was the 4th sunniest and 7th warmest on record as well as 11th widest temperature range. However, my abnormality index was not impressed and rated the month as entirely normal.
The Latest Month’s Weather in 8 Charts
The meteorological year starts in December which is why December appears as the 1st data point in the charts below. All data is supplied by the Met Office and can be found here. The dashboard below shows charts for 7 weather variables and a summary index as a single graphic. The middle bottom block explains why some data points are in black, points out the charts for Sunshine & Frost are swapped around according to the seasons and how the abnormality index (see next section) is calculated.
In July 2025, the Met Office extended their historical frost days data back to 1931.
How abnormal was April 2026?
Chart H displays my UK Weather Abnormality Index (see 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 63% this month which is in line with the median.
