The UK is currently experiencing a heatwave, with temperatures expected to peak at 34°C in parts of southern and central England on Thursday, according to the Met Office. This period of hot weather is likely to last until the weekend, bringing health warnings and travel disruption.
How long is the UK heatwave going to last?
The current heatwave is forecast to peak on Thursday, with temperatures reaching 34°C in the South East. A gradual cooling is expected from Friday, as a fresher Atlantic air mass moves in, bringing the heatwave to an end by Sunday for most of the country. However, the exact timing depends on the position of the jet stream.
How does this compare to the heatwave UK 2022?
The heatwave of July 2022 saw the UK’s first ever 40°C reading, making it far more extreme than the current event. This week’s temperatures, while high, are more typical of a standard summer heatwave, similar to the heatwave UK September 2023. The live ranking above shows how this event compares to other notable heatwaves in recent years.
What should you do during a heatwave?
Stay hydrated, keep out of the sun between 11am and 3pm, and check on elderly or vulnerable neighbours. The NHS advises closing curtains in rooms that face the sun and avoiding physical exertion. For pet safety, see the RSPCA’s advice on keeping animals cool. You can also check the UK weather hub for updated forecasts.
Is this a heatwave UK 2025 event?
Yes, this is the first official heatwave of 2025. The Met Office defines a heatwave as three consecutive days where daily maximum temperatures meet or exceed a specific threshold, which varies by UK region.
Will the heatwave UK today affect travel?
Yes. Rail operators may impose speed restrictions due to track buckling, and some roads could see surface melting. Check National Rail and your local council for live updates before travelling.
Could this be a heatwave UK 2026 preview?
It is too early to predict specific heatwaves for 2026. However, climate projections indicate that UK summers will see more frequent and intense heat events over the coming years.
