London & South East England weather forecast

Headline:

Windy, with sunny spells and blustery sharp showers.

Today:

Windy, with some sunny spells but also blustery scattered sharp showers. These showers will mainly affect the west at first, but should become more generalised later. Gales likely in exposure, making it feel cooler than temperatures may suggest. Maximum temperature 19 °C.

Tonight:

Becoming drier during the evening and overnight, with blustery showers becoming lighter, fewer and further between, mainly affecting the north and west. Remaining windy. Minimum temperature 10 °C.

Tuesday:

Cloudy at first in the north with a few further showers, however otherwise mainly fine with some sunshine, this becoming hazy as cloud thickens later. Feeling warmer as winds ease. Maximum temperature 20 °C.

Outlook for Wednesday to Friday:

Wet and windy midweek especially, but remaining unsettled throughout. Near-average temperatures by day, mild by night.
