The first weekend of August begins on a largely settled note for much of the UK, however, this is set to change as we start next week.
While a brisk breeze will persist along the North Sea coast on Saturday, particularly affecting eastern England, conditions elsewhere will be relatively calm and pleasant.
Through the morning, showers are likely to develop across parts of eastern England. These will peak around the early afternoon before gradually fading later in the day. Elsewhere, skies will be partly cloudy, with thicker cloud building across western Scotland and Northern Ireland. A few spots of rain are possible in these areas, but for the majority of the UK, Saturday will be a dry and bright day.
Temperatures will be close to average for the time of year. In the south, highs are expected to reach the low to mid-20s, while further north, values will range from the high teens to low 20s. Light winds and sunny intervals will make for a pleasant day for outdoor plans.

Change on the way overnight
As we move into Saturday night, a change in the weather pattern is expected. A cold front will begin to push in from the northwest, bringing a freshening breeze and outbreaks of rain. This system will initially affect Northern Ireland before spreading into Scotland, northern and western England, and Wales by dawn on Sunday.
The rain will be heaviest across North Wales and Northern England, as well as parts of Scotland. Further south, the rain will be lighter and more patchy in nature. By Sunday morning, the front will continue to move southeastwards, bringing cloudier skies and some rain to southern and southeastern parts of the UK by the afternoon.
Sunday: a more unsettled picture
Sunday will feel more unsettled compared to Saturday. Cloudier skies will dominate across southern areas, and it will be breezier throughout the day. While temperatures will still reach the low to mid-20s Celsius in the south, it may feel a little cooler due to the increased cloud cover and wind.
There remains the potential for some heavier showers along the cold front, particularly in East Anglia, where the odd rumble of thunder cannot be ruled out. However, these showers will be patchy and not widespread.
Behind the main band of rain, showers will continue across Scotland and Northern Ireland, though there will be some brighter spells in between, especially across Northern England and North Wales.

Looking ahead to Monday
As Sunday draws to a close, attention turns to a developing low-pressure system expected to arrive overnight into Monday. This system, named storm Floris, is forecast to deepen rapidly as it interacts with a powerful jet stream, unusually strong for the time of year. While there is still some uncertainty regarding the exact track and intensity of the low, current projections suggest a widespread area of rain and strong winds affecting much of the UK on Monday.
A yellow wind warning, issued on Friday, covers a swathe of the northern half of the UK, from Northern Ireland, north Wales, northern England, and the whole of Scotland where the strongest winds are more likely to be recorded.
The warning will be in force from 6am on Monday 4 August until 6am on Tuesday 5 August 2025.
The heaviest rain is likely across northern and western areas, with persistent rainfall expected throughout the day. The strongest winds are forecast to arrive after the main band of rain clears, during the second half of Monday and into the early hours of Tuesday. Gusts of 50–60 mph, possibly higher in exposed areas, could lead to disruption, particularly for those travelling, camping, or attending outdoor events.
