If Saturday feels like a washout, don’t write off the rest of the week. Cornwall starts under grey skies and outbreaks of rain, but the regional forecast has it turning fine by the end of the weekend and warmer still into the new week.

Today

Saturday 19 September is cloudy across the South West, with outbreaks of rain and drizzle spreading through the day and brisk winds to go with it. The cloud thickens at times, thick enough to bring fog around the hills and along northern coasts, so visibility could drop in places. Despite the grey, it stays warm, reaching a maximum of 22°C.

Tonight

It stays cloudy and damp through the evening, so the wet start carries on for a while yet. After midnight things gradually turn drier, with variable cloud and clear spells opening up and the winds easing down. The minimum drops to around 12°C, a fresher feel than the day.

Sunday

Sunday 20 September is the turning point. It is a drier, brighter day with light winds, and it feels pleasant whenever the sun comes through. Those sunny spells grow through the afternoon, so the later you get into the day, the better it looks. The maximum reaches 21°C.

Monday to Wednesday

The fine theme holds into the new week, with plenty of dry weather and sunny spells. The nights turn chilly at first, with patchy fog forming where the air is coldest, so early risers may want an extra layer. Then the trend tips warmer, with temperatures climbing above average as the week goes on. After a soggy Saturday, that is quite a turnaround.
