Today, we have seen some of the warmest temperatures in the UK recorded in Usk in Monmouthshire - at 21.3°C.
After a lovely summer's evening, it will remain mild overnight, with some mist and fog patches in the Valleys and coastal areas early tomorrow morning.
It should be clear away, to leave a fine and sunny when most of us go to work in the morning though.
Tomorrow looks like another hot day - with temperatures up to 21°C inland - a little bit cooler on the coast.
It looks likely to be warmer still on Saturday - up to 22°C - before things turn unsettled again late on Sunday and into the start of next week.
