What makes Risca’s weather different from nearby towns?
Risca lies in the Ebbw Valley, surrounded by hills that influence how weather systems arrive. Low cloud and mist can linger longer here than on the coast, especially overnight and into the morning. During settled summer spells, the valley shelters the town from stronger winds, often producing warmer afternoons than more exposed upland areas.
