Apart from the odd shower it will be a dry evening with some late sunshine. Overnight cloud will tend to increase with the breeze also freshening. Minimum temperature 13 °C.

Monday:

Any early brightness quickly replaced by a band of rain which will spread eastwards throughput the morning. The rain will be heavy at times, give a rather wet afternoon. Breezy. Maximum temperature 19 °C.

Outlook for Tuesday to Thursday:

Rather changeable throughout the period with a mix of sunshine and showers interspersed with a longer spell of rain on Wednesday. Temperatures near average for early June.

Updated: 04:00 (UTC+1) on Sun 31 May 2026

UK long range weather forecast

Atlantic low pressure systems will continue to push showers or longer spells of rain east across the UK. The best of the drier conditions are usually more likely towards the south and east, with more frequent rain across the west and northwest. Drier weather may start to become more dominant through the second week of June. Temperatures will be near-normal overall, with the warmest spots most likely across eastern areas. It will also be breezy at times, especially across western parts, and notably so around some coastal areas.

Updated: 13:00 (UTC+1) on Sat 30 May 2026

Drier and more settled weather may develop as high pressure becomes more dominant, although some showery interludes are still possible. The forecast turns more mixed towards the end of the month, with rain and showers perhaps having more of an influence. Temperatures likely to trend above average as we head further into June, with very warm spells possible in places.
