Wales weather forecast

Headline:

Sunday:

A cloudy start to the day with brisk winds, and a risk of showers. Showers becoming more isolated into the afternoon, with a chance of some brighter spells. Maximum temperature 20 °C.

Outlook for Monday to Wednesday:

Largely dry through the start of next week, with variable cloud and sunny spells, and a small chance of isolated showers on Monday and Tuesday. Turning warmer through the week.

Updated: 16:00 (UTC+1) on Sat 25 Jul 2026

UK long range weather forecast

Dry at first across the south with sunny periods, where it will also be very warm. Cloudier in the north with showers or some longer outbreaks of rain, which could be heavy in places, and temperatures nearer normal. It will probably become more changeable thereafter, with potential for an area of low pressure to move close to or across the UK at the start of August. This could bring spells of heavy rain and perhaps some strong winds for a time. It may become more settled again toward the end of the first week of August.

Updated: 13:00 (UTC+1) on Sat 25 Jul 2026

Dry and settled conditions will probably dominate much of this period with high pressure patterns tending to affect the UK. This may be interrupted at times by Atlantic frontal systems, especially in the north, or thunderstorms in the south. However, overall rainfall amounts will likely be below normal. Temperatures will probably be above normal and some spells of hot weather and heatwaves are possible, especially in the south.
