Lewes (East Sussex) weather

Headline:

Some rain moving east Sunday, clearing later. Rather windy Monday.

Today:

Some early sunshine across eastern parts. Cloud soon thickening from the west through the morning with outbreaks of rain following through the afternoon, these turning increasing light and patchy, before slowly clearing through the evening. Maximum temperature 22 °C.

Tonight:

Generally dry overnight. Clear periods initially but cloud gradually thickening from the northwest, perhaps bringing the odd patch of rain to the north towards daybreak. Mainly light winds increasing later. Minimum temperature 14 °C.

Monday:

Rather windy and cloudy Monday, with outbreaks of rain moving east through the afternoon, followed by drier and brighter conditions into the evening. Maximum temperature 25 °C.

Outlook for Tuesday to Thursday:

Blustery winds Tuesday with sunny spells and the odd shower possible. Winds ease Wednesday, largely dry with sunny spells. Breezier and cloudier Thursday but mostly dry. Temperatures trending warmer later.

This period likely starts with something of a north-south split. Some locally heavy rain or showers, with a risk of thunder, will likely affect the north, along with some strong winds, whilst the south looks like starting mainly dry with some warm sunshine and lighter winds. There is a chance of some rain or showers even in the south, but more likely it will be mainly dry and warm here. Temperatures will probably be close to average in the north at first. As we move towards the middle of the month, there is an increased chance of high pressure becoming more dominant, leading to drier, more settled conditions becoming more widespread with above average temperatures. However, some brief unsettled spells remain possible, particularly towards the end of this period.

High pressure, and therefore fairly settled conditions overall, appears most likely for the second half of August. Although dry weather is likely to dominate, periods of rain or showers and thunderstorms may develop at times, these perhaps more likely later in the period. Above average temperatures overall seem most likely, with the potential for hot spells to develop, especially in the east and south.
