This is the Met Office UK Weather forecast for the weekend 21/08/2025. It’ll be a fine weekend with a mix of cloudy periods and sunny spells and most places staying dry, it’ll also warm up by a few degrees by Monday. Bringing you this weekend’s weather forecast is Alex Deakin
00:00Hello. It isn't a bank holiday, a weekend everywhere across the UK, but everywhere will be under the influence of high pressure, which means pretty much everywhere will have a dry weekend.
00:11Here's the area of high pressure slowly edging in from the west. There are weak weather fronts trying to come in with it, and they will introduce a fair bit of cloud, so it's not necessarily going to be sunny all weekend.
00:22Way out over the Atlantic, we're keeping a close eye on this weather system. It's a hurricane at the time of recording, but as it moves northwards and across the mid-Atlantic, it will cease to be a hurricane, but it could still influence our weather later next week.
00:38For the time being, though, and into what is, as I say, for many of us, except Scotland, a long weekend, high pressure will be the dominant feature. That's going to bring a lot of dry weather.
00:47It will bring still a fair bit of clouds across the country on Saturday, and in places that cloud may be thick enough for the odd light shower, but the vast majority won't see those.
00:58It'll stay dry. It may start quite sunny in quite a few places, but when we see sunny skies to begin with, some cloud will bubble up through the day, but equally, if it starts grey, I'm hopeful that cloud will break up a little bit.
01:09So dry and bright pretty much sums up the weather. The winds are going to be light, easing off across the east coast, where they have been nagging away for much of the week.
01:18So feeling a bit warmer here, certainly 1920 degrees with some sunny spells across the south, likely to reach 22 or 23 Celsius.
01:26One thing we will notice, those temperatures just picking up a little bit as we go through the weekend.
01:30The high pressure is still with us for Saturday night and Sunday.
01:34It does start to edge out into the North Sea, and again, weak weather fronts trying to push in from the west, but generally failing.
01:41Still quite a bit of cloud trapped under this area of high pressure.
01:44It's always hard to pin down exactly where that cloud is going to be, with nothing really to shift it.
01:49But again, thick enough for the odd light shower here and there, but the vast majority with high pressure sinking air, we will stay dry.
01:57And again, the sunshine making a big difference to the feel of the day.
02:01So if you have decent spells of sunshine, we're likely to see those temperatures getting up to the low 20s, maybe the mid 20s across the south, 24, maybe 25 degrees Celsius.
02:11Those temperatures compared to average, pretty close to it for the time of year across England and Wales.
02:16This map comparing those temperatures to the mid-month average, but those orangey colours for Scotland and Northern Ireland suggesting temperatures here a few degrees above that mid-month average.
02:27And if anything, Monday is going to be warmer still, more likely to get certainly in the south up to 25, perhaps 26 degrees Celsius and further north more widely into the low 20s as well.
02:37So as I said, it is going to get warmer through the weekend, generally getting sunnier as well.
02:42By the time we get to Monday, not a bank holiday in Scotland, but it is elsewhere across the UK.
02:48I think we'll see more blue skies generally.
02:51Just a bit more of a breeze, perhaps picking up across the south and the cloud is starting to gather behind me.
02:56Again, the cloud may be thick enough as it bubbles up elsewhere for the odd, very light shower.
03:01But under that high pressure, most places dry.
03:03Out in the Atlantic, though, that weather system we saw earlier.
03:06By this stage, by the time we get to Monday, it will not be a hurricane, but you can tell by the number of isobars on it, still quite an intense area of low pressure.
03:16At the moment, likely to be sitting out in the Atlantic by the time we get to Monday.
03:19But its exact track and how it changes and ceases to be a hurricane will influence our weather as we go through next week.
03:26But certainly for the weekend, most places set fair, dry and bright.
