Updated: 04:00 (UTC+1) on Tue 14 Apr 2026

UK long range weather forecast

A few showers around at the start of the period, mainly affecting the northwest where it will also be windy for a time. For many though the weekend should be fine and dry with spells of warm sunshine, but still some chilly nights. Into the following week fronts associated with another Atlantic low will try to push into the UK, but may struggle to make inroads against an area of high pressure to the northeast. So the greater chance of some rain is for western areas, while northern and eastern areas may well see plenty of dry weather. Temperatures likely remaining above average.

Updated: 13:00 (UTC+1) on Mon 13 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.
