The British Isles experienced severe winter weather on 9 January 2025, with temperatures plummeting to -13.3°C in some regions. The cold snap prompted widespread ice and snow warnings across the UK, adding to over 60 flood alerts issued earlier on 8 January.

An amber cold health alert was also in place for all of England, highlighting the risks of extreme temperatures until 12 January. The weather caused major travel disruptions across air, road, and rail networks and led to school closures throughout Wales, England, and Scotland.
