Saturday will begin on a rather cloudy note, particularly across western areas where some rain or drizzle is expected, especially on upslopes. However, as the day progresses, many parts of the UK will see an improvement, with brighter and sunnier conditions developing across Scotland, Northern Ireland, eastern Wales, and much of eastern, southern, and central England.

Western parts of England and Wales, along with some areas in the north of England, are likely to remain mostly cloudy throughout the day. Rain and drizzle will persist in these regions, again favouring higher ground, though some breaks in the cloud may develop in the lee of hills.

It will feel notably humid across England and Wales, with temperatures rising higher than on Friday. The southeast is expected to be particularly warm, with maximum temperatures reaching 29 to 30°C. A breezy day for many, especially in the far north, where winds may be more noticeable.

Overnight, most areas will remain dry with variable cloud cover and some clear spells. Western areas and parts of northern England will be cloudier, with the potential for light rain or drizzle, particularly near coasts and on hills. It will be another warm and muggy night across England and Wales, although temperatures may dip slightly compared to the previous night. Further north, conditions will feel fresher.

Outlook for Sunday

Sunday will see a band of cloud and rain across central parts of the UK gradually edging northwards. This rain may ease for a time before turning heavier in the far northwest later in the day. Southern areas will start cloudy with some patchy drizzle on western hills, but there will be plenty of dry weather too, with sunny spells developing.

Winds will generally be light to moderate, though coastal areas in the north may experience fresh to strong winds, with a risk of coastal gales early on. Temperatures will be near normal in the north, but warm or very warm elsewhere, and hot once again in the southeast.

The hottest day of the current spell is expected on Monday, with temperatures widely exceeding 30°C in central and eastern England, possibly reaching 34°C in London and towards Cambridge.

Met Office presenter and meteorologist, Alex Deakin, said: “The weekend is going to be a hot one. For most of us, though, it's going to be a fairly grey start and it will be quite a damp start through central Scotland, parts of Northern Ireland. That rain should be edging away to the south, so Belfast cheering up, Glasgow, Edinburgh also looking brighter by the time we get to Saturday lunchtime, and a much brighter day overall for the Highlands of Scotland.

“Still quite breezy, quite a gusty wind blowing here. Quite a grey day over the far north of England, rain on and off across Cumbria. North Wales likely to see a bit of rain, particularly Anglesey at times. But a good chunk of England and Wales will stay dry and we'll have some sunshine, certainly for East Wales, much of southwest England, the Midlands and eastern England too. And it's in this eastern zone where we'll see the highest temperatures, likely to get up to 29, 30 degrees in and around the capital.

“So, the heat starting to pick up through Saturday and into Saturday night. It'll be very warm. We'll continue with a zone of cloudier weather over Cumbria bringing some rain and drizzle, northern parts of Lanarkshire, and again the far northwest of Wales. But either side of it, many places staying dry and staying fine on Saturday evening, a balmy evening certainly across the south. The winds will be lighter in southern areas on Saturday compared to today.

“On Sunday, again a very warm night, so a humid start. And still a zone of cloudier weather over parts of Northern England, North Wales. The rain should be petering out, but we may see another pulse of rain just pushing back towards Northern Ireland later on. For most places, though, Sunday is dry. Again, a much cooler, fresher feel across Scotland and Northern Ireland compared to further south, where again, where we see some sunshine, and it perhaps won't be quite as sunny on Saturday, a bit more cloud around, so again that humid feel. We should still get up to 30, perhaps even 31 in the capital."
