High pressure is likely to dominate across the UK at the start of this period and through to the end of the year.

It may often be rather cloudy, but any rainfall that does develop is expected to be light with overall accumulations small. Winds will mostly be light with temperatures close to or slightly below normal. Into 2026, little change is anticipated through the first week of January, with settled and mainly dry conditions continuing for many parts of the UK. However, there is a small chance that more unsettled, wetter and milder weather could develop at times, particularly in the north.
