UK Temperatures Soar as Heatwave Nears 34C
The UK has matched its hottest May day on record after temperatures climbed to 32.8C in Teddington, southwest London, amid an intense heatwave sweeping across England and Wales.
Forecasters say temperatures could rise even further, with some areas expected to reach 34C in the coming days. The prolonged spell of hot weather has already pushed eight regions in southern and eastern England into official heatwave territory after temperatures remained at or above threshold levels for three consecutive days.
Health officials have issued amber heat-health alerts across parts of the Midlands and eastern England, warning of potential impacts until at least Wednesday.
Meteorologists predict Monday and Tuesday will be the hottest days of the week, with temperatures widely reaching the mid-30s in southern Britain. Monday is expected to bring the most widespread heat, with all four UK nations likely to experience their warmest conditions of the year so far.
Wales could also see history made, with temperatures threatening to break the country’s May heat record of 30.6C, set in Newport in 1944.
Not only daytime temperatures are under scrutiny. Forecasters say overnight warmth could also challenge records, with the possibility that some locations remain warmer than the current May night-time record of 18.9C, recorded in Folkestone in 1947.
Relief in Sight?
The heatwave may trigger isolated thunderstorms across parts of central England and Wales on Tuesday, though these are expected to be scattered and unlikely to provide lasting relief.
A temporary cooling trend is forecast for Wednesday, particularly across eastern and southeastern England, where cooler air moving in from the North Sea could lower temperatures by five to 10 degrees.
Despite this, Wales and southwestern England are expected to stay hot, protected from cooler coastal breezes, with temperatures still capable of reaching 30C.
By Thursday, warmer air from France is forecast to return, pushing temperatures upward once more and bringing 30C conditions back to several areas.
Weather models suggest more noticeable relief will arrive next weekend and continue into early June, as the jet stream shifts southward. This change is expected to bring cooler temperatures, stronger winds and periods of rain.
Why Is It So Hot?
The heatwave follows unusually warm conditions that developed across southwestern Europe last week and reflects a broader pattern linked to climate change.
Climate experts say Europe is warming faster than any other continent, leading to more frequent and intense heatwaves. Even by midsummer standards, the current spell of heat is considered exceptional — particularly for May.
Historically, temperatures above 30C in May have been rare in the UK. Conditions reaching the mid-30s were once uncommon even during peak summer, yet such temperatures are now being recorded before June begins.
With the UK typically experiencing its hottest weather in late July or early August, forecasters warn that even higher temperatures could still lie ahead later this summer.
