UK long range weather forecast

A much more unsettled period than of late with the whole of the UK likely to see showers or some longer spells of rain, but also some drier and brighter interludes. For Sunday and Bank Holiday Monday it's likely a story of sunshine and showers. The showers will be heavier and more frequent in the west where it may also be windy, especially across the northwest. The east, especially the southeast may well see a good deal of dry weather. The rest of the week then sees further frontal systems run into the UK, bringing more widespread rain at times, but again some drier spells in-between these. Temperatures will probably be close to average, perhaps slightly above at times, but will feel fairly cool in the often strong winds.

Updated: 15:00 (UTC+1) on Tue 20 May 2025

Changeable weather conditions are expected as we head into June although with time a trend toward longer settled spells seems likely. So spells of wet weather with showers or longer spells of rain are likely to be interspersed with drier, sunnier periods these drier periods may become more prevalent as we had further into June. Overall, it will likely be wetter in the west and drier in the east. Temperatures will probably average out around normal, although some very warm or even hot spells are still possible, as normal for the time of year.
