Thursday:

A grey and overcast start to the day with patchy rain and drizzle. However, conditions are expected to turn drier and brighter through the afternoon, with a noticeable breeze developing. Maximum temperature 22 °C.

Outlook for Friday to Sunday:

Friday brings warm sunshine and mostly dry conditions. The weekend turns increasingly unsettled with strong winds, cloud and showers or longer spells of rain. It becomes noticeably colder by Sunday.

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.
