Sunday, July 12, will maintain the summer feel, bringing long sunny periods and a noticeable breeze, though temperatures will still reach the low to mid-20s across Barry and the coast.
By Monday, July 13, the heatwave pattern remains, with warm air, a mix of sunshine and some cloud, and afternoon values again widely into the 20s, only easing slightly compared with the peak of the heat.
