UK long range weather forecast

Atlantic weather systems will continue to bring spells of rain, showers and occasional strong winds. The wettest and windiest conditions are most likely across northern and western areas, although wet and windy weather may extend more widely at times. Between these unsettled spells, periods of drier and more settled weather are likely, especially in the south and east, where they may last for a few days. Temperatures are expected to be slightly above normal overall, but overnight fog and frost is possible during clearer, cooler nights.

Updated: 13:00 (UTC+1) on Sun 20 Sep 2026

Through October, changeable and occasionally unsettled weather is likely to become more frequent, with spells of rain moving in from the Atlantic. Between these periods, drier and brighter interludes are expected. As is often the case for October, deeper areas of low pressure may also bring periods of very strong winds, especially across the north and west. Temperatures are expected to remain slightly above average overall, although brief cooler interludes are possible.
