UK long range weather forecast

During this period, conditions will probably be more changeable than they have been recently, with low pressure systems becoming more likely. This means an increasing chance of showers or longer spells of rain, with a risk of strong winds at times. Some dry spells with some warm sunshine are still likely at times too, with a risk of a few short-lived early morning fog patches. Temperatures are likely to be close to or slightly above normal.

Updated: 13:00 (UTC+1) on Sun 26 Apr 2026

Low pressure systems will probably dominate across the UK at the start of this period. This means showers or longer spells of rain are likely at times, heavy in places, with a risk of strong winds. Temperatures will probably be close to or slightly below normal. Later in the month, more settled and drier conditions may begin to develop, with temperatures perhaps rising slightly above normal.
