Forecast for Wales

  • 14 hours ago
  • Updated Monday to Friday only

Latest forecast for South East Wales

Today

After any local patches of fog lift, today will continue widely sunny and hot. There's a low chance that daytime heating may trigger the odd thundery shower in spots during the afternoon.

Tonight

Tonight will remain warm under clear skies and a gentle north-easterly breeze. The odd patch of fog could form locally but will quickly disperse around dawn.

Saturday

Tomorrow will be another hot and sunny day, albeit temperatures will be a touch lower than the previous day for many. Winds will continue from the north-east, gentle to moderate.

Outlook for Sunday to Tuesday

Widely sunny and hot on Sunday through Tuesday with temperatures in the high twenties to low thirties. However, instability over north France could bring some thundery showers northwards late on Monday evening, some persisting overnight until Tuesday morning. The risk of showers diminishes by Tuesday evening.
