2025

Winter 2024-25 was unexceptional, being slightly milder overall than the long-term average.


January. A lively month. Overall a cool month, with mean temperatures a little below the 1990-2020 averages. There was some heavy snow across much of England and Wales in the first week, with a rare "amber" weather warning for snow for the Midlands, Wales, and the North on 4-6th January. The Pennines suffered in particuar. There was flooding in the north and midlands when the thaw came, but the mild weather in the south didn't last long, with some low temperatures as Arctic air came flooding in, with the lowest temperature on the night of 8-9th being -12.4C at Tulloch Bridge (Highland); also -11.0 at Shap (Cumbria) and -7.8 at Sennybridge (Powys); then -14.4 at Altnaharra on the morning of the 10th. The maximum at Altnaharra on the 10th was just -10.8, and then it fell to -18.9C on Friday night (10-11th) - the coldest January night in the UK in 15 years. Milder air started slowly spreading from the west on Sunday 12th. 94.0 mm of rain fell at Seathwaite (Cumbroa) on the observing day ending on the 14th. The temperature at Altnaharra on the 14th reached 14.3, which was a rise of 32.7 over three days, a new record for the UK. It was settled for a while but then on the 24th Storm Eowyn hits the British Isles. It's a weather bomb, where central pressure drops by more than 24 mbar in 24 hours; it's generated in a very active jet stream when a cold plunge over America meets warmer air in the Gulf. Many homes lost power and Galway recorded the highest ever speed of a gust of wind speed in the Republic at 114 mph. There was a rare "red" warning for wind across the central belt of Scotland. A gust of 100 mph was recorded at Drumalbin (South Lanarkshire), and 99.1 on the Queensferry crossing between Edinburgh and Fife. In England the highest gust was 96 mph at Brizlee Wood (Northumberland) and in Wales 93 mph in Gwynedd. Northern Ireland recorded its lowest ever January sea level pre ssure with just 948.1 mbar at Magilligan (Londonderry) on the 24th. Storm Herminia brought more wet and windy weather to the south at the month's end. The highest temperature of the month was 15.7 C at Cassley Sutherland on the 14th and at Aboyne (Aberdeenshire) on the 15th. Rainfall across the UK was about average, but it was wet in southern England and dry in Scotland and Northern Ireland. It was though a sunny month, with a UK average of 61.8 hours (130%); it was particularly sunny in the north.

February. The month began with a blocking high giving cold easterly winds but as easterlies aren't what they were it wasn't exceptionally cold. The high started moving away on the 19th, allowing frontal systems to bring some snow to the north, but then mobile westerlies meant the rest of the month was changeable and mild.  There was some heavy rain in the west on the 23rd, particularly over South Wales, leading to flooding. The end of the month was quieter. Overall the month ended above average for the CET; Northern Ireland was particularly mild. It was quite a dry month, with a UK average of 72.7 mm (76%); it was particularly dry across northern England. The first half was dull but the second half quite sunny, and overall the UK saw not far from average sunshine (67 hours, 93%), although northern Scotland was particularly sunny. The highest temperature of the month was 17.0°C at Hull East Park on the 21st, and the lowest -9.6°C at Aviemore on the 14th. The heaviest rainfall was 111.2 mm, falliong at White Barrow (Devon) in the observing day ending on the 24th.

March. A very anticyclonic month and as a consequence very dry. Only Shetland recorded above average rainfall. It was the second driest March on record for Norfolk and Suffolk, beaten only by March 1929, and the sixth driest for England as a whole. It was the sunniest March on record in England, the second sunniest for Wales, and the third sunniest for the UK overall (158.1 hours, 145% average). There was some frost and fog, and overall it was warmer than average, with maximum temperatures being particularly high. Scotland and Northern Ireland were much milder than average. It reached 19C in Cumbria on the 9th but then a cold front brought some snow to Scotland. The highest temperature of the month was 21.3 at Northolt in London and Chertsey (Surrey on the 20th; the lowest temperature of the month was -9.0 at Tomintoul (Banffshire) on the 18th.
