Cornwall Set for 32°C Heat This Bank Holiday Monday

Get the sun cream ready, because the next few days are going to be a scorcher across Cornwall.

Forecasters are predicting a hot, dry and sunny spell over the bank holiday weekend, with temperatures climbing well above what we would normally expect for late May.

A warm start to the week

Today, Sunday 24th May, began with sunshine and temperatures rising quickly through the morning. The day is set to stay dry with plenty of hot sunshine and light winds, though it will feel rather humid. The maximum temperature is expected to reach 28°C.

Tonight will stay dry with some late evening sunshine, followed by clear skies across the region. It will remain rather warm overnight, with a minimum temperature of 15°C.

The big one: Monday

Bank holiday Monday is shaping up to be the hottest day of the lot. Forecasters expect a hot and humid day with plenty of strong sunshine and light winds, and the mercury is set to hit 32°C.

If you are heading to the coast, you may find things a touch more bearable. It will feel slightly fresher by the sea thanks to a sea breeze.

What happens next

The hot weather is not going anywhere fast. From Tuesday through to Thursday, it will stay hot, sunny and mostly dry, with temperatures well above average for the time of year.

There is one small change on the horizon. Thursday may bring a little more patchy cloud, and perhaps the odd shower.
