Wales weather forecast

Headline:

Often cloudy this week but perhaps some sunshine in places.

A mostly cloudy, dry and rather mild night to come in the east. Best of the cloud breaks are in the west, where some patchy fog and mist may form and it will turn chilly. Minimum temperature 4 °C.

Thursday:

Little change in the weather pattern on Thursday. Remaining rather cloudy, dry with light winds. Some brightness, mainly in the west, with temperatures near the seasonal norm. Maximum temperature 15 °C.

Outlook for Friday to Sunday:

Remaining settled, mostly cloudy and dry at first with some brighter spells and overnight fog. A change on Sunday as rain and brisker winds arrive from the west.

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

UK long range weather forecast

A rather unsettled pattern is likely through much of this period, as low pressure systems originating over the North Atlantic trundle east or northeastwards across the UK. These will bring showers or longer spells of rain, perhaps accompanied by some strong winds at times, but also interspersed with some drier and brighter interludes, albeit these generally of shorter duration than the recent settled spell. Later in the period, there may be a transition to a slightly cooler and more showery northwesterly regime, as high pressure builds over the Atlantic to the west, and low pressure becomes centred to the east of the UK. Temperatures are likely to be near or slightly above average overall, although may trend slightly below normal later

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

It is likely to be changeable at first, with a showery northwesterly regime most favoured across the UK. Into November, an unsettled pattern is anticipated, as low pressure systems over the Atlantic track across the UK. These may be shifted farther south than normal, bringing showers or longer spells of rain fairly widely, perhaps also accompanied by some strong winds at times. Temperatures will probably be close to or slightly above average overall.
