- Wales logged its 10th wettest autumn since 1836, with November reaching 224.4mm of rain—59% above the monthly norm—and reports of flooding and surface water problems.
- England saw a clear north–south divide, with northern areas around 45% wetter than average and the south about 17% wetter, while Northern Ireland was 39% above average and had its fifth dullest autumn since 1910.
- Met Office short-range forecasts point to a changeable, cool week in the south east, with heavy showers likely from Thursday and a risk of locally thundery bursts into the weekend.
