Cornwall weather: Wednesday 12 August, 27°C sunshine peak midweek

If you have been holding out for a day to get on the water or up onto the moor, this is the one. Cornwall sits under clear skies and rising heat today, with Truro the warmest it will be all week before things soften off towards the weekend. Here is how the whole run of the week’s weather forecast shapes up.

Today

Today, Wednesday 12 August, is the pick of the week. Truro reaches a high of 27°C under full sun, with an overnight low of 16°C. Rain is as good as absent, the chance of any sitting below 5 percent, and the breeze stays light for a summer’s day, gusting to around 19 mph. This is a sun cream and shade by early afternoon sort of day rather than a coat sort of day.

Tonight

Temperatures ease back to around 16°C overnight. A mild night to follow the day’s heat, and the last of the fully settled nights before the pattern starts to shift later in the week.

Thursday

Thursday 13 August keeps the run going. Another sunny day, a touch down on Wednesday at a high of 25°C, with a warmer night behind it at a low of 18°C. The rain chance stays under 5 percent and gusts hold at 19 mph.

Friday

Friday 14 August is when the sky starts to break up. Sunny intervals now rather than wall to wall sun, 23°C by day and 15°C overnight. There is a small 10 percent chance of a shower around 4am, and the wind edges up a little to 22 mph.

The weekend

Saturday 15 August holds onto its sunny intervals but slips to 21°C, the coolest day of the stretch, with a 10 percent chance of a morning shower around 10am and gusts of 22 mph. Sunday 16 August is the turn. Cloud moves in, the day sits at 22°C, and the chance of rain climbs to 30 percent by late evening, around 10pm, with wind still at 22 mph.

Into next week

Monday 17 August carries that greyer feel into the new week. Cloudy again at 22°C, a 30 percent chance of rain around 7am, and the strongest wind of the forecast at 26 mph. After a stretch of sunshine that peaks today, the settled spell has an end date, and by the start of next week the cloud and the rain chance are both on the way back up.
