Cornwall weather: Tuesday 28 July, 28°C humid midweek peak

Dig out the sun cream and keep it handy, because the next few days are set up for you. The regional forecast for South West England, which covers Cornwall, points to a mostly dry spell with plenty of very warm or hot sunshine, and a sticky Wednesday looks like the high point before the air turns fresher.

Today

Tuesday begins grey in places, with areas of low cloud and hill fog that lift and break through the morning. Once they clear, very warm spells of sunshine build for the afternoon. It feels breezy first thing, though the wind soon falls light. The maximum temperature is 25°C.

Tonight

A fine end to the day brings some evening sunshine, followed by clear spells overnight. Some areas of low cloud reform as the night goes on, so expect a little hill fog to return. It stays warm, with a minimum temperature of 15°C.

Wednesday

Wednesday is the one to watch. Early low cloud and hill fog clear to leave plenty of sunshine, but more cloud edges in from the northwest as the day goes on. It turns hot and feels humid, with a maximum temperature of 28°C.

Thursday to Saturday

Thursday arrives fresher, with sunshine and perhaps the odd shower to break things up. Friday and Saturday stay mostly dry with further sunshine developing at times, and it stays warm whenever the sun is out. Whether that lone Thursday shower stays a maybe is the only real question hanging over the week.
