UK long range weather forecast

Changeable and often unsettled conditions are expected to affect the UK during this period. The most likely weather pattern is one of successive areas of low pressure moving in from the west or southwest and then tending to become rather slow-moving in the vicinity of the UK. This means a story of showers or longer spells of rain, with almost anywhere seeing some heavy rainfall at times, but the greatest chance of wetter than normal conditions will be in the west. Any snowfall is most likely over higher ground in the north. Strong winds are also a possibility from time to time, again perhaps more likely in western areas. Given the changeable pattern originating from the Atlantic, temperatures will most likely be close to or a little above normal.

Updated: 14:00 (UTC) on Fri 28 Nov 2025

A broad continuation of the weather patterns experienced in early December is the most likely scenario through this period. This means low pressure is likely to carry on dominating the UK's weather, especially through the middle part of December. Further spells of rain, interspersed by clear, showery interludes, along with some windy conditions at times; again the wettest conditions are more likely to be in the west. Later in December, there are still hints of something a little less unsettled developing, though long-lived dry spells look unlikely. Temperatures remaining close to or perhaps a little above average overall.
