Wales weather forecast

Headline:

More rain and cloud, brighter on Sunday. Very mild.

Today:

Cloudy with patchy drizzle through the morning and occasional brighter interludes, particularly in the east. More rain arriving into the afternoon, this turning heavy and persistent over high ground. Windy and feeling very mild. Maximum temperature 12 °C.

Tonight:

Further outbreaks of rain likely but it should turn drier from the north and west later in the night. Clear spells developing across Anglesey, northern Gwynedd and Conway towards dawn. Minimum temperature 5 °C.

Sunday:

A cloudy start for many but clear or sunny spells already across the north will become widespread. A few showers likely into the afternoon. Feeling pleasantly warm in the sunshine. Maximum temperature 11 °C.

Outlook for Monday to Wednesday:

Turning unsettled on Monday with cloud and rain arriving. Often mild with strong southwesterly winds at times. Similar both Tuesday and Wednesday, but there will be some drier interludes too.

Updated: 04:00 (UTC) on Sat 21 Feb 2026

UK long range weather forecast

Changeable during this period with Atlantic frontal systems moving across the country and shorter dry and bright interludes in-between. Rain and showers typically heaviest and most frequent in the west, with more sheltered eastern areas seeing much smaller amounts of rain. Often windy with a chance of gales at times. Temperatures well above average at first, likely falling closer to average with alternating colder and milder spells towards the end of February and into March; perhaps cold enough for some sleet/snow showers in the northwest, especially over high ground, in the colder spells.

Updated: 14:00 (UTC) on Fri 20 Feb 2026

A continuation of rather changeable conditions is the favoured scenario, with low pressure systems tending to pass close to or across the UK, bringing occasional spells of wet and windy weather, especially in the north and west. High pressure to the southwest may build across the UK at times to bring some drier, quieter interludes, these more likely later in this period and probably most influential in the south - the chances of prolonged settled weather look very low. Temperatures are likely to be near or slightly above average for the period as a whole, though some relatively short-lived interludes of colder conditions remain possible.
