Forecast

Cwmbran's weather is influenced by its location near the Atlantic Ocean and the surrounding hills. This combination brings lots of rainfall and mild temperatures throughout the year.

The hills surrounding Cwmbran block some winds, creating a rain shadow effect, which means less rainfall and lower air pressure compared to coastal areas.

In winter, low pressure systems from the Atlantic bring strong winds and heavy rainfall, with pressure often below 1000 hectopascals. This makes winter days windy and wet.

In summer, high pressure systems dominate, bringing calm and sunny weather, with pressure often above 1020 hectopascals. This makes summer days warm and pleasant.
