People flocked to the beach in Porthcawl on Tuesday as Wales sweltered in 33C heat
Parts of Wales could to be hit by two heatwaves this week, with the third heatwave of the year underway and a fourth possible at the weekend.
A high of 33C is forecast for Tuesday, with some of the hotspots likely to be in Monmouthshire.
Thursday is likely to be somewhat cooler and will end the current heatwave, but temperatures will rise again into the weekend, BBC Wales weather presenter Sabrina Lee said.
"To experience 33C in August in Wales is actually pretty unusual. We have some data that goes back to 1930, and since then we've only had highs of 33C during five August months," she said.
