UK long range weather forecast

High pressure is likely to dominate across the UK through to the end of the year, centred to the west over the North Atlantic. This will likely maintain relatively settled conditions at first, but with a few showers possible along some coasts exposed to the northerly wind. Towards the first weekend of January, high pressure is likely to shift a little farther away from the UK, allowing a greater chance of more changeable conditions to develop. This will bring an increased risk of some rain or showers at times which, with cold air close to the UK, may bring some wintry hazards to some places. Temperatures will probably be near or slightly below average for this period overall.

Updated: 14:00 (UTC) on Wed 24 Dec 2025

Whilst confidence is low, high pressure will probably sit close to the UK initially, with periods of relatively settled weather interspersed with more changeable conditions. Temperatures will likely be near or slightly below average during this time. Later in the period a transition to more widely changeable or unsettled conditions is possible, with a corresponding shift to near or slightly above average temperatures.
