UK long range weather forecast

Likely remaining unsettled with showers or longer spells of rain across all areas at times. Rainfall amounts will probably be above average for the time year with the wettest conditions in the northwest. Potential for some strong winds at times. Some drier and more settled interludes could develop, perhaps becoming longer in duration across southern areas later in this period. Temperatures are likely to be near average, although some short-lived warm or very warm spells are possible, especially in the south.

Updated: 13:00 (UTC+1) on Wed 26 Aug 2026

Most likely a continuation of the generally unsettled conditions at first with showers or longer spells of rain across many areas. However, likely some drier interludes at times. Further into September, drier weather may become more prevalent, especially in the south and southeast, with more unsettled conditions tending to become more likely further north and northwest. Temperatures will probably be near normal at first but may become warmer later, with the possibility of some hot spells in the south.
