It’s fair to say we’ve been blessed with the weather this year. 2025 has seen the sunniest March and April since records began in 1910, while we’ve already had more sunshine this spring than the whole of last summer.

But sadly, the old-fashioned British bank holiday forecast seems to be back in business with sun, rain and cloud forecast across the three-day weekend. Saturday morning (May 24) kicks off with heavy rain until 9am before it changes to cloudy conditions.

Some sporadic showers can be expected throughout the day although it will stay mostly. It should still be quite mild, with the temperatures set to reach 21C. Sunday is likely to be the best day with the same highs of 21C and sunny spells.

The evening should have the best conditions of the entire weekend. This being said, it may feel colder than it actually is due to a strong winds with gusts reaching 43mph in the afternoon.

On Monday forecasters expect cloudy weather throughout the day and highs of 19C. There is a slight chance of rain in the early afternoon, with the current possibility at 40 per cent.

Similar conditions are expected throughout next week with the mercury hovering between 20-21C. The Met Office says the change in weather compared to early spring is due to weather systems moving in from the Atlantic Ocean.

Deputy Chief meteorologist David Oliver said: “These weather systems will bring rain and windier conditions from the west later Friday, which will spread across the whole of the UK on Saturday. Some heavy rain is expected, especially in the northwest later on Saturday when winds will also strengthen, bringing a risk of coastal gales in the north.

“Strong winds will continue on Sunday as an area of low pressure passes the northwest of the UK. Blustery showers are expected on Sunday, which will be heaviest and most frequent in the northwest. Conversely, the south and southeast may well see a good deal of dry weather. Wind will be a watchpoint for Sunday, especially across Scotland where there is some uncertainty on the exact track of the low and its associated wind speeds, so keep up-to-date with the forecast as it evolves over the coming days.”
