@Official_WXUK Isnt it due to air mass and jet stream

We should've expected a record breaking late May heatwave as soon as we knew the first half of the month was going to be a bit cooler than normal... whole months below avg just don't happen these days and the swing to make up the difference is nearly always dramatic 😂

@MetWatchUK @SnowbieWx Is @SnowbieWx part of the Met Office? How does he have the statistics? What is his meteorological background?

@Adam47154269176 @SnowbieWx is the man to ask for those stats

A big warmup coming up this week! Today temperatures are struggling to climb above 13-15C, but by the weekend southeast England could see the first 30C in May since 2005. Increasingly likely the heat will last into next week as well! #ukweather

@KSuit2222 @SnowbieWx What is the earliest date for the first 20C, 25C, 30C for the 1961 to 1990 period

@SnowbieWx Thank you, could be an interesting summer this year!

If 30C is achieved in the UK this coming Saturday, it will be the earliest 30C since 1952. All metrics earlier than average in 2026 First 20C: 18th March (avg 5th April) First 25C: 8th April (avg 5th May) First 30C: 23rd May possibly (avg 30th June)

@SurreyPalmsWX Despite the warmth next week, May as a whole will be below average. Wouldnt it be ironic if the May max month record is beaten but the month as a whole is below average

There is growing possibility that the UK’s all-time May temperature record COULD be challenged next week. 🌡️ Latest GFS 12z has two consecutive days of 31C and 7 days of 26C+ for London with the heat peaking on Tuesday/Wednesday next week. 🥵 I wouldn’t rule out 32-33C now. 👀

@NickJF75 What's the uk average for may so far

Unsurprisingly, the Mean CET is below average up to the 17th (-0.7C below the 1961-1990 May average). However, the only way is up this week & likely temps will stay above average for the rest of the month. So probably be around average months end. Makes a change from well above months since January

@Petagna @AEMET_Esp Why

A dramatic change in the weather developing across Iberia this next week.. from frost and snow to 34C and tropical nights (min temps >=20C)!! 🌡📈📈 See @AEMET_Esp

@TheSnowDreamer Proof that our weather is controlled by the jet stream

25-28c seems like a realistic target area right now across a fairly large area. Regardless it’s a massive shift to 10-13C!

Strange when feeling current coolness and how massively different it could be in near future. Model output hinting at relatively intense Spanish plume scenario which entertains 30C temps later next week. Solutions like this from ECMWF are not isolated this evening - currently I put it at 20% chance.

@RyanWeather Be more specific what happened in 1927 and 1977 etc

Major things happen in intervals of 50 years in climate 1776, 1826, 1876, 1926, 1976, 2026 ... 1777, 1827, 1877, 1927, 1977, 2027 ...

@TakeThatClouds @TheSnowDreamer Yes but that is just natural variation due to jet stream. The average highest max for whatever 30 year cycle you look at in the 20th century is 30C or above

@TheSnowDreamer Yeah it’s ridiculous. People losing the plot because it’s 12C in the second week of May. A 1960s style summer would freak them out. Imagine a summer that never even reached 28C once these days!

My impression many of you have an inflated sense of what a British spring should be like. Today’s dynamic weather is not crazy really this is springlike, many weeks at time without rain is not normal. Recency bias is obvious. Yes recent weather is rather unseasonable for mid May, it would be more appropriate in April, nearly all of spring until now though has been behaving 1 month ahead. Some small balance…

@MarkVogan What does it mean

Big flip coming for much of Europe. A hint of upcoming summer, esp NW?

@TheSnowDreamer What do u mean by 2.5C warming

A look at the warmest max temperature in month of May each year from 1949 to 2025 at London Heathrow. May 1953 holds highest monthly max of 31.7C (89F) this 73 year old record is oldest of all months with +2.5C of warming since then. Then followed by June 1976 (34.8C). Definitely overdue!

@TheSnowDreamer What's the coldest may max on record

Unseasonably cool afternoon… temps in capital have fallen to single digits in the rain. As cold as it can get this late in spring.

@wanstead_meteo What's the coldest may max temp on record

Chilly overnight. The low of 0.7C was the coldest May night for 5 years. Yesterday's max of 12.7C was also the coldest May max temp for 5 years.

@MetJam_ What's the coldest may max

A minimum of 1ºC this morning was the coldest May night in 5 years here in Reading (6th May 2021, -0.1ºC) and the fourth coldest 4th of May on record since records began in 1908. It would not surprise me if tonight's minimum was a little colder, last May air frost was in 2020.

@wanstead_meteo But to say the month is above average doesnt mean anything at the moment because were less than 1 week in!

The max so far today is just 13.8C, over 3C below average. The mean for the month, however, is running over 2C warmer than average.

@TheSnowDreamer I notice that Spring 2021 was in the top 10 coldest

April 2026 was another much warmer than average month in London finishing +1.8C above 1991-2020 normal. The month ranks as 5th warmest April back to 1948, right now we are on course to see the third consecutive notably "warm" spring unless May changes course.

@TheSnowDreamer Is this normal

Unusual temperature distribution today in Europe just shy of 30C in Berlin 🇩🇪 some 20C cooler in Turkey 🇹🇷 where mountain snow is falling this evening. Opposing extremes.

@TheSnowDreamer What about temp wise

Preliminary but 4.6mm at #London Heathrow will make April 2026 the tied 3rd driest April on record. In approaching 80-year record we see that 4 of the top 5 driest Aprils have occurred since 2007. #climate

@MetJam_ Where do u get the maximum temperatures for the month I.e. this graph that you have

A final figure of 26.6°C at Kew Gardens beats the previous date record of 24.4°C at Brixton in 1894 by 2.2°C. This is an idea of how it looks in the historical record since 1875 - a very notable spike.
