Updated: 04:00 (UTC) on Mon 26 Oct 2026

UK long range weather forecast

A band of rain will make erratic eastward progress at the start of this period, clearing to the east or dying out as high pressure becomes more dominant in the vicinity of the UK. Into early November, high pressure will most likely be the dominant feature near the UK, meaning drier than normal conditions for most if not all areas, though it could be rather cloudy and grey at times. If light winds and/or clear skies combine overnight, then areas of fog could develop. Overall, temperatures are likely to be close to normal, but with the potential for cold nights with some frost.

Updated: 13:00 (UTC) on Sun 25 Oct 2026

Probably settled at first, perhaps with some chilly nights. Moving further into November, there is an increased chance of more unsettled conditions developing, with a return to spells of rain and potential for strong winds. However, the extent and location of wettest or windiest areas is uncertain. Overall, temperatures will probably be near or a little above average.
