Wales weather forecast

Headline:

Turning very warm or hot over the next few days.

This Evening and Tonight:

A warm and largely sunny evening but perhaps cloudier in the west. Generally dry overnight with clear periods, thicker cloud in the northwest. Milder than last night, though cooler in the countryside where patchy fog is possible in prone spots. Minimum temperature 11 °C.

Monday:

Hazy sunshine through the morning but skies gradually clouding over. Scattered showers may move northwards later, perhaps giving a few rumbles of thunder, especially by the evening. Feeling very warm. Maximum temperature 28 °C.

Outlook for Tuesday to Thursday:

Very warm or hot on Tuesday with plenty of strong sunshine. Probably turning less hot thereafter but remaining very warm in the east. Often bright but isolated thundery showers possible.

Updated: 17:00 (UTC+1) on Sun 10 Aug 2025

UK long range weather forecast

High pressure will likely build leading to a period of fairly dry and settled weather for many at first, with a few light showers in the north. There may however be some heavy, thundery showers over the weekend, especially in the south. Temperatures will likely remain above normal, and much of the south could still see warm or very warm temperatures for at least a couple of days. There is a possibility that the heat could last further into the week, especially in the south. Beyond this high pressure will likely continue leading to plenty of fine weather, perhaps with the odd heavy shower or thunderstorm. Temperatures will likely continue to be above normal but there are some signs of fresher conditions developing in the north later.

Updated: 15:00 (UTC+1) on Sun 10 Aug 2025

High pressure, and therefore largely settled conditions overall, appears more likely at first. Although dry weather is likely to dominate, periods of rain or showers and thunderstorms may develop at times. Above average temperatures overall seem most likely but there may be some fresher interludes in the north at first. There remains potential for further hot spells to develop, especially in the east and south. By the turn of the month, there are signals for high pressure to become less dominant with perhaps a greater chance of some rain, though there is some uncertainty in this aspect of the forecast.
