UK long range weather forecast

High pressure is likely to lie close to the UK at the start of this period. Most places will be dry with sunny spells and light winds, although there could be some overnight mist and fog. Into the first week of May, conditions will probably become more changeable 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. Temperatures are likely to be close to or slightly above normal.

Updated: 13:00 (UTC+1) on Sat 25 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, drier conditions may begin to develop with temperatures perhaps rising slightly above normal.
