South West England weather forecast

Headline:

Some brighter breaks to end the week.

Today:

A damp and cloudy start with showers continuing to feed in from the west, these often heavy. Turning brighter through the afternoon as cloud lifts, with some sunny spells emerging in the west. Breezy at times near coasts. Feeling mild. Maximum temperature 11 °C.

Tonight:

Turning increasingly cloudy from the south this evening as a heavy band of showers pushes northwards overnight, bringing prolonged downpours and strong winds to southern coastlines. Frost-free. Minimum temperature 8 °C.

Saturday:

An unsettled start as further blustery showers feed in from the south through much of the day. These clearing northeastwards later, allowing some brighter and drier spells. Winds easing. Maximum temperature 11 °C.

Outlook for Sunday to Tuesday:

Sunday brings a mix of showers and sunny spells, before turning unsettled from the west again to start the new week, with further bands of heavy rain. Breezy at times.

Updated: 04:00 (UTC) on Fri 6 Feb 2026

UK long range weather forecast

Predominantly cyclonic patterns are expected to dominate the UK. Further fronts are likely to approach the UK at times and then become slow-moving as they butt up against high pressure to the north or northeast of the UK. Thus some southern and western areas remain most prone to seeing the wettest conditions, which will maintain sensitivity to further flooding impacts. Parts of northeast Britain may also be wetter than normal. Some snow is likely, especially in any colder airmasses that filter south or east into the UK and/or on the interface between mild and cold air. Strong winds are also possible at times. Temperatures will remain finely balanced during this period, with northeastern areas more likely to be colder than average, and southwestern areas perhaps seeing mild conditions at times.

Updated: 14:00 (UTC) on Thu 5 Feb 2026

Broadly changeable conditions are expected across the UK during this period. Low pressure systems will probably dominate, meaning showers or longer spells of rain, heavy at times, for much of the UK and some hill snow in the north. Periods of strong winds are also possible, especially around coasts. Temperatures will likely be close to average or slightly above overall, though there remains the potential for incursions of colder air at times, at least into northern areas.
