The warmest year in the UK on record: in the England CET series (11.15, beating 2014 at 11.0), England overall (10.94), Wales (10.23), Northern Ireland (9.85) and Scotland (8.50), with the UK overall exceeding 10 C for the first time (at 10.03). 2021 and 2022 are the only known examples of 30C being exceeded in Northern Ireland in two successive years.
Overall, winter 2021-22 was mild: the eighth warmest since 1884, depending on the exact measure, although most of those even milder have been since and including 1988. Some extraordiary summer heatwaves, smashing the British record, and with temperatures over 40 C recorded for the first time in Britiain. The period January-July was the second warmest on record, with every month above temperature, and to August every month has had beneath average rainfall. Summer 2022 was the equal joint hottest on record (with 2018), and was also very dry (the fifth driest since 1836 in England). It was a sunny summer in England, but a dull one in Northern Ireland. On combined measures of sunshine, temperature, and rainfall, it was the third best summer since 1910. It was the third warmest autumn on record (since 1884).
January. The very mild end to December 2021 continued into the start of January. A record high temperature for New Year's Day, with 16.3 ºC recorded at St James's Park in London, beating the previous record from 1916. After this mild start it became colder, with milder interludes, and a windy mild end. The lowest temperature of the month was -8.0 at Topcliffe (North Yorks.) on the 6th. The first ten days were unsettled, but then most of the rest of the month was very anticyclonic. Overall it was milder than average, particularly the further north you went. Frosts were rare in Scotland and common in England, a reverse of the usual pattern. It was a very dry month except in western Scotland, with the UK overall having 50% of the long-term average. It was most noticeably a very sunny month, except in NW Scotland, with 132% of the average, making it the third sunniest in the UK since records began (in 1919), and the sunniest on record in England.

It was also very wet, with 152% of the long-term average. It was sunny in the east but less so in the west. It was very stormy midmonth with named Storms Dudley and Eunice. Dudley affected mostly southern Scotland, parts of Wales, and northern England, with winds of 101 mph recorded. Storm Eunice on Friday 18th brought exceptional gales, estimated to be the strongest since the Burns Day Storm of 1990, to the south coast, with a (provisional) new record gust for England of 122 mph recorded at the Needles (IOW). Sadly at least three people died. The highest temperature of the month was 18.2 ªC at Pershore on the 16th, and the lowest -8.1 at Braemar on the 11th.
