Wales weather forecast

Headline:

Turning frosty tonight, then mostly sunny tomorrow.

This Evening and Tonight:

There will be some low cloud around this evening, especially in the north. However, this will break up overnight, with clear periods developing across the country. A widespread frost will form, along with the odd freezing fog patch. Minimum temperature -1 °C.

Tuesday:

Patchy cloud may affect some western coasts at times tomorrow. Elsewhere frost and any fog will clear to leave a fine and sunny day with mostly gentle winds. Maximum temperature 11 °C.

Outlook for Wednesday to Friday:

Wednesday looks dry with some sunshine, though a little breezy. Clouding over during Thursday with some showery rain developing later, and into Friday. Some frost at first, but turning milder.

Updated: 16:00 (UTC) on Mon 3 Mar 2025

UK long range weather forecast

Likely mild at the start of this period and feeling warm in any sunny spells. However, conditions will be fairly changeable with a chance of showers or longer spells of rain across all areas, these more likely, at least at first, in the west. How weather patterns evolve during the following week is unclear but there is an increased chance that high pressure will become more dominant for a time from the north. This would result in a good deal of dry weather but also lead to a downturn in temperatures with a low chance of a colder spell and wintry hazards. Low confidence by the end of the period but with an increasing chance of milder but more unsettled conditions developing again.

Updated: 14:00 (UTC) on Mon 3 Mar 2025

Confidence is low in prevailing weather patterns through this period. There is likely to be a mixture of unsettled and settled spells but it is unclear which will be more dominant. As is typical, parts of the west and northwest will probably be wetter overall with drier conditions in the southeast. Above average temperatures are more likely than below though some colder spells remain possible during late March.
