I believe some have reacted in disbelief to hearing the UK across summer had an average temperature of 16.5C and this was sufficient to make it the hottest summer on record. The average T treats the overnight low and max equally, so it will not feel representative. (1/2)

Hi all, I'm currently in Amsterdam, that's why I've gone quiet! I can still announce #London Heathrow, unsurprisingly with average temperature of 21.5C experienced its hottest summer on record. A remarkable +3.4C above already warmed 1991-2020 climo and over 1 degree warmer than 2nd hottest 2018.

Warmest May-Aug at London Heathrow (avg max temp) 🥇 2026: 25.95C (assuming Aug finishes 27.5C) 🥈 2018: 24.45C 🥉 2022: 24.40C 2025: 24.38C 1976: 24.12C Pretty extraordinary since May 1st, London has averaged a high of 26C which is 1.5C higher than previous hottest in 2018.

A sweltering start to September in southern Europe peaks of 40-43C are expected in Spain on Thursday. The weather has turned more unsettled in late August in NW Europe but we are far from out woods yet. Immense heat is near the Earth is exceptionally warm.

Last hours of what has been a summer of insanity not forgetting May! In London I’m expecting Summer 2026 to be 1.6C hotter than 1976! 0.3C separated it from 2018 the hottest, not anymore…

Proper rain at last here in SE16 lashing it down.

Shallow low pressure area across UK today and we was still just shy of 25C in London and Suffolk. Crazy how warm given set up! The Euro model forecast 21C…

The week ahead looks rather unexciting as we step into meteorological #autumn. There are however signs towards next weekend the jet stream will lift north and we may see a summery ridge of high pressure. Finely poised. Become a patron to discover more. www.patreon.com/posts/168112...

Meteorological #Autumn is rapidly closing in on Northern Hemisphere and the days grow shorter, but the weather has not got that memo. Strong “summer” heatwaves dominate continents. Global temperature anomalies have never been higher on eve of a new season.

It wasn’t as cool as you think the max of 21.4C just 0.7C below normal high for the date. Tomorrow will be 80th consecutive day since #London Heathrow last had a daily max below 20C. Seems clear we will break 2022 record of 85 consecutive days. The longest streak in 1976 summer 39 days!

I keeping hearing talk about a September heatwave it bears no truth. A July-like heatwave will take hold across S half of Europe next week but for UK we look to maintain a flat westerly profile. Likely turning more settled further south but no high temps are expected. Nights will be most mild.

feels like London has taken a different climate classification in recent months. Even on this more unsettled blustery day still getting dregs the proper rain keeps going north or south. I’ve seen only 3mm since midnight locally most of models indicated 10mm+ 😶 (1/2)

Recently heard a distant rumble coming from southeast according to radar. Downpours currently in between Croydon, Bromley and Orpington.

Wet weather will be focused on south tomorrow where it has largely evaded as Atlantic low passes through. The frontal rain looks to start near 10am in London a push back from earlier guidance. Following the more persistent rain a feature with heavy rain also looks to sweep east later in afternoon.

Unpleasant high humidity today and not a storm in sight 😵‍💫

The London storm/weather shield remains in excellent order the Midlands lit up like a Christmas tree. ⚡️ For such a hot summer to produce nothing is twisted. Apart from one active overnight storms in June it has been crickets. (1/2)

2026 is running very hot we saw January open up uneventful as ranked 31st warmest of the 79 Januaries (1948-present). January 2026 (31/79) February 2026 (3/79) March 2026 (7/79) April 2026 (5/79) May 2026 (1/79) June 2026 (1/79 July 2026 (1/79) August 2026 (1*/79) London Heathrow data…

I am anticipating August 2026 will be record warm August in London, 2022 holds it for now which slightly edged out 1995. It would be the fourth consecutive record-breaking month which started in May. Truly unprecedented these past few months, nothing comes close in persistence and magnitude.

A look at the late August bank holiday weekend for patrons. It will be unsettled at times accompanied by blustery winds, but it’s not all gloom and doom with Azores high building into BH Monday…. www.patreon.com/posts/167848...

Think that’s a you problem. Confidence was low on daytime potential. Also today was never looking cooler or wetter or suggested to be, rather very warm and humid the warmest day of the week.

I'll believe it when I see it. So far all these yellow weather warnings have been for nothing. Today was 27° not what I'd call 'cooler' and it certainly wasn't 'wetter'

Elevated thunderstorms have started crossing English Channel⚡️

As daylight fades massive storms are erupting in France. This deep instability is moving northwards towards our shores.

Sunset is 8pm tonight in London the final one at this hour the next 8pm sunset is 234 days away, 17th April 2027 🫣

Midnight tonight through to 8am Thursday on 12z UKV 👀 #thunderstorms

Met Office have rightly issued a thunderstorm warning for overnight and through Thursday AM. It namely concerns heavy rain threat, places may see half a month’s worth of rain in 1 hour. Amongst that potential for prolific lightning, large hail and strong convective gusts. #London #flashfloods

A reminder of our very fragile existence. I said it during Blatten glacier collapse last year a devastating event like this would come sooner rather than later. Rocketing global temperatures, loss of high elevation permafrost/glacial ice the glue which holds it together is being lost. (1/2)

A massive flash flood in the Himalayan border areas of Nepal and ‌China's Tibet. Initial report say it may have been caused by a glacial lake rupture.

V warm and muggy tomo expecting high twenties 🥵 Heavy showers are expected to break out late morning near London more to north involving Midlands moving NW. Capable of producing intense rainfall and ⚡️ big uncertainty on whether more scattered or part of something more organised and widespread.

Well this would be a typical evolution from tonight’s European model. An unsettled bank holiday weekend and then summer 2.0 emerges when kids go back to school.

That breezy easterly wind is ongoing this afternoon but very nice indeed. Blue skies and 26c in west London. Pity we did not have more of these comfortable warm sunny days over summer.

There's growing model consensus that a broad area of heavy rain (thundery?) will push northwards across England and Wales on Thursday. The first significant rain in several months, seems the bulk of rain will have cleared early by dawn in London.
