UK long range weather forecast

Atlantic low pressure systems will continue to push showers or longer spells of rain east across the UK. The best of the drier conditions are usually more likely towards the south and east, with more frequent rain across the west and northwest. Drier weather may start to become more dominant through the second week of June. Temperatures will be near-normal overall, with the warmest spots most likely across eastern areas. It will also be breezy at times, especially across western parts, and notably so around some coastal areas.

Updated: 13:00 (UTC+1) on Sat 30 May 2026

Drier and more settled weather may develop as high pressure becomes more dominant, although some showery interludes are still possible. The forecast turns more mixed towards the end of the month, with rain and showers perhaps having more of an influence. Temperatures likely to trend above average as we head further into June, with very warm spells possible in places.
