Wales weather forecast

Headline:

Changeable next few days, with sunshine and some showery rain.

This Evening and Tonight:

Lingering patchy rain will clear eastwards this evening, leaving scattered showers overnight, mixed with some clearer spells. A milder night than the previous night with winds easing by dawn. Minimum temperature 10 °C.

Friday:

Isolated showers first thing Friday morning, but dissipating under a ridge of high pressure. This leaves brighter spells in the afternoon, especially in the west. Temperatures will be near average. Maximum temperature 20 °C.

Outlook for Saturday to Monday:

More wet and windy weather returns on Saturday, followed by another ridge of high pressure and drier weather on Sunday. Staying autumnal into next week with further spells of rain.

Updated: 16:00 (UTC+1) on Thu 10 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

High pressure initially close to the UK, with a continuation of more settled conditions at times, may start to weaken its influence on the weather later in the month and into early October. As a result, it may become more changeable with a greater chance of rain or showers in places, and perhaps some strong winds at times too. Temperatures will likely be a little above average overall, with relatively cool nights possible at first tending to reduce in frequency later in the period.
