Monday:

Any early brightness quickly replaced by a band of rain which will spread eastwards throughout the morning. The rain will be heavy at times, giving a rather wet afternoon. Breezy. Maximum temperature 19 °C.

Updated: 16:00 (UTC+1) on Sun 31 May 2026

UK long range weather forecast

Changeable early in this period with Atlantic frontal systems moving across the UK. These will bring showers or longer spells of rain at times, with wettest conditions in the northwest, driest in the southeast. Strong winds may affect parts of the UK at times, especially the northwest. Later in the period, higher pressure and drier weather may begin to become more prevalent, especially in the south. Temperatures are likely to be near normal overall.

Updated: 13:00 (UTC+1) on Sun 31 May 2026

Fine and dry across many areas at first with high pressure the dominate pattern across the UK. Winds will mostly be light with temperatures probably above normal. Later, low pressure will probably begin to have more of an influence, especially across the south where heavy showers and thunderstorms become more probable.
