UK long range weather forecast

Changeable at the start of this period with low pressure to the west or northwest of the UK. This will bring showers or longer spells of rain at times, heaviest and most persistent in the northwest, together with some strong winds. The southeast is likely to be driest and brightest. Later in this period, conditions may become drier and more settled, perhaps more especially in the north or northwest, with the south possibly becoming the focus for showers or longer spells of rain. Temperatures will likely be near or slightly above average overall.

Updated: 13:00 (UTC+1) on Sun 12 Apr 2026

The dominant pattern during this period is most likely to be high pressure (or higher than average pressure) to the north and lower pressure to the south. This will probably lead to drier and more settled than normal weather in the north or northwest of the UK, with the south and possibly east more unsettled and wetter than normal. Temperatures will probably be close to or slightly above average overall.
