South West England weather forecast

Headline:

Feeling chilly with sunshine and blustery showers.

Today:

It will be a chilly feeling day for all, but also bright with some sunny spells. Some heavy, blustery showers are possible, mainly in the east, with a risk of hail. A brisk northerly wind adding to the colder feel. Maximum temperature 13 °C.

Tonight:

Showers easing but a few persisting overnight with the brisk northerly wind continuing. Feeling rather chilly, especially in the wind. Minimum temperature 8 °C.

Thursday:

Winds will gradually ease through the day, but scattered, blustery showers continue with some with hail and thunder possible. Temperatures remaining below average for mid-May. Maximum temperature 12 °C.

Outlook for Friday to Sunday:

Drier and brighter on Friday and Saturday with perhaps the odd shower, winds mostly light too. Rain arriving from the west on Sunday. Temperatures slowly increasing, but still below average.

Updated: 04:00 (UTC+1) on Wed 13 May 2026

UK long range weather forecast

Changeable and at times rather unsettled conditions look to dominate at first, with low pressure often close by. This means periods of rain or showers, some of which could be heavy, for many places, though some drier interludes are also expected. As this period progresses, high pressure is likely to begin to build from the south bringing more in the way of settled weather. Temperatures likely cooler than average to begin, but tending to recover as the period progresses, perhaps becoming rather warm by the end of the period, especially in the south.

Updated: 13:00 (UTC+1) on Tue 12 May 2026

Patterns which bring more settled weather are more likely to dominate towards the end of May. Whilst further rain and showers are possible at times, there is likely to be longer spells of fine and dry weather. Into June, more mixed conditions are likely with spells of rain and showers, but also some drier weather at times. Temperatures are most likely to be near or slightly above average overall, with some warm weather possible at times.
