UK long range weather forecast

With high pressure expected to remain in place for much of the UK, fine weather and light winds are likely to continue for most places. Although perhaps not as warm as the start of the week, temperatures will still be warm or very warm inland, but it will feel cooler near the coast, especially with an onshore breeze. Some patchy rain may affect the far northwest at times, with perhaps a few showers in the far south.

Updated: 13:00 (UTC+1) on Fri 22 May 2026

High pressure is more likely to prevail across the south and east, with lower pressure further north and west. Rain and showers are still possible at times, mainly across Northern Ireland and Scotland. During mid-June, rain and showers may occur more widely for a time. Drier weather is expected between any bouts of wetter weather - these drier interludes will tend to last longer across the south and east of England. Temperatures are most likely to be near or slightly above average overall, with some warm or very warm weather at times.
