Sunday 27th July 2025

Often cloudy is the vibe for this forecast. Generally warm, some sun, some showers too.

Thanks to Isabel for the photograph (even if it is on the border of Berkshire…I don’t get enough photographs to be that choosy!).

Not much change in the general pattern, high pressure dominates to our south-west, which means we have a westerly/north-westerly flow – the latter does tend to bring a lot of cloud, which it has done and will do.

So Sunday will be rather cloudy. Some sunny breaks at times, but cloud is the main vibe, if also quite bright. A 30% chance of a heavy shower later in the day – if showers develop they will be very scattered. Around 21’C in a north-westerly breeze. Reasonably clear skies overnight, down to around 13’C.

Monday will see a fair amount of cloud but a bit more in the way of sunny spells than on Sunday. Some showers bubbling up too, around a 40% chance of catching one or two during the day. Warmer, around 24’C but also quite breezy. Clear skies for a time overnight, cloud thickening later – down to around 15’C.

Tuesday starts rather cloudy, with a weather front crossing. Some uncertainty on rain amounts – it will be rather showery in nature and a fairly small feature, so it could just be dribs and drabs, though I think more likely there will be at least some heavy showers mixed in. A chance of some sunshine in the afternoon, but the shower risk will remain. More likely around 22’C or so, but if sunshine amounts surprise then up to 25’C is plausible. Showers still possible in the evening/overnight though gradually becoming more scattered, and generally it will be rather cloudy. Around 16’C.

Plenty of cloud again for Wednesday, some sunny spells and a 30% chance of a shower or two. Around 23’C in a light north-westerly (ish) breeze. Some cloud, some clear spells overnight – down to around 15’C.

Not much change in the set-up for Thursday, if anything high pressure will have retreated west somewhat.

Plenty of cloud likely once more, some sunny spells and probably some showers, say a 60% ish chance of a couple of heavy showers later in the day, or evening – potentially very heavy with a rumble of thunder. Around 23’C or so.

Friday sees more of a northerly flow and probably more influence from low pressure to our east – so again plenty of cloud, some sunny spells and a greater chance of showers, say a 70% chance of at least a couple of heavy showers, potentially very heavy/torrential and thundery. Temperatures around 22’C.

Next weekend is fairly uncertain – the somewhat more likely outcome sees further showers, a general continuation of the week before.

But perhaps high pressure will instead build across the UK – this is what I expect to happen at some point after the beginning of August, but in time for next weekend is a bit of a stretch. However, tropical storm developments are hinted at off the coast of the USA, which could be enough to nudge high pressure more towards us.

Generally I expect mid/late August to see more in the way of sunshine and warmth – we should return to something like summer.

And maybe this continues into autumn too. Weak signals, but signals nonetheless of high pressure dominating early autumn.

Have a good Sunday.
