For some parts of Wales it's glorious summer sunshine, but the further east you go during the Sunday the more likely you are to encounter cloud. Temperatures could reach a nice warm 23C but that could trigger off the odd shower.
It will feel a touch cooler around some coasts with light northerly breeze pinning back temperatures.
It will be warm overnight with lows remaining in double figures. Lows of 11C. Winds fall light enough in places to see a little mist forming.
Bank Holiday Monday is likely to be the best day overall across Wales with more sunshine on offer across the country. Expect to see some fairweather cloud bubbling up and it's likely to be a touch warmer too with highs of 24C.
