Cornwall weather: Sunday 30 August, showery with 34mph gusts

If you had washing pegged out or a last beach day of the summer holidays in mind, keep half an eye on the sky. Cornwall sees August out under a mix of watery sunshine and sharp showers, with the wind loud enough to notice, before the picture calms down for the opening days of September. Here is how the rest of the Cornwall forecast shapes up.

Today, Sunday 30 August

Sunday brings light showers coming and going through the day, with a high of 20°C that feels nearer 18°C once the breeze is in the mix. There is a 50% chance of catching a shower at any given hour, so the brolly earns its spot by the door. The wind does as much of the talking as the rain, gusting up to 34mph and giving the coast path a proper buffeting. The low sits at 15°C.

Tonight

Overnight the showers turn more insistent, the chance of rain climbing to somewhere between 70 and 90% by the small hours. It stays mild for the time of year, holding around 16°C, so it feels muggy rather than cold under the cloud.

Monday 31 August

Monday is the August bank holiday, and it looks a good deal kinder. Sunny intervals push through once any early showers clear, and while the chance of rain starts the day at 50% it falls away to 10 to 20% by the afternoon. The high eases back a touch to 19°C, the night dropping to 13°C, and the wind stays fresh with gusts to 32mph.

Tuesday 1 September

September opens quietly. Tuesday keeps the sunny intervals going, the odd early shower aside, with a 30% chance of rain first thing fading to 10 to 20% as the day goes on. Temperatures nudge back to 20°C and the wind finally loosens its grip, gusts easing to 23mph. The overnight low is a mild 17°C.

The rest of the week

Midweek settles into something steadier. Wednesday turns cloudy but warm at 21°C, a 40% chance of early rain thinning out later and gusts back up to 31mph. Thursday is the pick of the week for anyone chasing brightness, sunny intervals and only a 10% chance of rain as the new school term starts, the temperature again reaching 21°C. Friday and Saturday cloud over, both overcast and sitting around 20°C, the rain chance a modest 30% and the wind dropping right off to 20mph gusts by Saturday.

What to watch

So the shape of it is a wet, blowy finish to August handing over to a calmer, warmer run into September, though the cloud never quite clears out for long. Whether Thursday’s sunshine holds through the weekend or the overcast wins the argument is the part still up for grabs.
