WARNING

Flood warnings in force for England

Environment Agency

South West England weather forecast

Headline:

Cloudy with outbreaks of rain. Breezy.

This Evening and Tonight:

Cloudy this evening with further spells of rain and drizzle intermittently through the night, heaviest in the north and over the Moors. Remaining windy, especially at the coasts, and feeling rather muggy overnight. Minimum temperature 15 °C.

Thursday:

A cloudy and mild start to Thursday with some drizzle in places. Turning drier through the afternoon with some brighter intervals. Feeling humid and staying windy. Maximum temperature 20 °C.

Outlook for Friday to Sunday:

Remaining changeable with showers or longer spells of rain at times. Some brighter periods are also likely, mainly on Friday. Temperatures close to average but turning colder through Sunday. Breezy.

Updated: 17:00 (UTC+1) on Wed 17 Sep 2025

UK long range weather forecast

Into next week, a northwest-southeast split is most likely. The best of drier spells will be in the north and northwest where some fog and frost patches are possible, but there will be spells or rain or showers in south and eastern areas, near to an area of low pressure. It will also turn colder, as a northerly flow becomes established for a time. Later in the week, more widely drier and settled conditions could develop as high pressure becomes more influential, although probably still with some coastal showers. Temperatures should gradually return closer to average in this period. Later in the period there may be a return to a more changeable pattern but this is uncertain.

Updated: 15:00 (UTC+1) on Wed 17 Sep 2025

By the beginning of October, confidence is very low in the weather regimes most likely to affect the UK. On balance, there will likely be a transition from slow-moving weather patterns to a more changeable period at some stage although the timing on this is highly uncertain. High pressure probably close to the UK, which would offer some occasional periods of dry weather, will likely give way to a more unsettled period with some short lived dry interludes during this time. Temperatures will likely fluctuate either side of, but often close to, average.
