Met Office Forecast for South-West England

Headline: Gusty winds for some overnight, sunny and warm on Sunday.

This Evening and Tonight: Sunny and warm this evening, then dry and mostly clear overnight with some high cloud at times. Gusty south-easterly winds in parts of Devon and Cornwall and rather warm here. Otherwise a slightly fresher night overall with lighter winds. Minimum Temperature 12C.

Sunday: Another dry and very warm day with strong sunshine for most. Perhaps cloudier across the Isles of Scilly. Breezy with easterly winds staying particularly gusty in some western areas. Maximum Temperature 27C.

Outlook for Monday to Wednesday: Breezy at times on Monday and somewhat cloudier with showers or thunderstorms possible in the west, though many places staying dry. Mainly dry thereafter with isolated showers. Staying warm.

UK Outlook for Thursday 21 Aug 2025 to Saturday 30 Aug 2025: High pressure is likely to be the dominant feature at first, initially centred near to Iceland, allowing a north to northeasterly airstream to affect much of the UK, leading to rather cool conditions. High pressure is likely to progress SE across the UK for a time, bringing widely fine and dry conditions and for some, an increase in temperatures, relative to the previous few days. Whilst this is happening a deep area of low pressure is likely to develop in the North Atlantic, linked to Tropical Storm Erin. The final week of August may see Atlantic weather systems progress over the UK, especially in the north and west, with a small chance of widely wetter and windier weather developing. The evolution of this is highly uncertain though.

UK Outlook for Sunday 31 Aug 2025 to Sunday 14 Sep 2025: Confidence in the details through this period is low. However, low pressure and therefore unsettled or changeable weather looks more likely, and with this comes the potential for stronger winds at times as well. Whether this takes the form of further low pressure systems running in from the Atlantic, or a rather more slowly evolving weather pattern with the potential for heavy showers is less clear. Temperatures are likely be near to above average overall.
