Wales weather forecast

Headline:

Wet and windy on Saturday.

This Evening and Tonight:

Dry with clear spells initially. However, it will cloud over from the north after midnight with rain arriving by dawn. Strengthening southwesterly winds, with a risk coastal gales across Gwynedd and Anglesey later. Minimum temperature 8 °C.

Saturday:

A band of cloud and rain already across north Wales will gradually sink south across the country during the day. Some heavier bursts possible. Rather windy, with temperatures near normal. Maximum temperature 20 °C.

Outlook for Sunday to Tuesday:

A damp start to Sunday with rain and drizzle, before another area of rain arrives from the west for Monday. Fresher on Tuesday with sunny spells and a breeze.

Updated: 16:00 (UTC+1) on Fri 11 Sep 2026

UK long range weather forecast

Remaining changeable, with occasional rain or showers arriving from the North Atlantic, most frequent across northern and western parts of the UK, where some strong winds will also be possible at times. However, there will also be some reasonable dry and more settled periods, especially across southern areas. Later in the month, high pressure may become more dominant in the vicinity of the UK, perhaps bringing more widely settled conditions for a time, especially away from the far north. Temperatures for the period as a whole will probably be close to average overall, but there is scope for some rather warm days at times, along with occasional relatively cool nights.

Updated: 13:00 (UTC+1) on Thu 10 Sep 2026

Most likely remaining changeable, with further spells of rain and showers arriving from the North Atlantic. Strong winds possible too at times, these most frequent across the north and west. Some short-lived settled spells are also possible, these most likely in the south. Temperatures for the period as a whole will probably be close to average overall.
