As the UK braces for another heatwave with temperatures expected to reach 34C, the UK Health Security Agency has issued heat health alerts for all of England starting from Tuesday morning until Wednesday. The alerts have been raised from yellow to amber in five areas, indicating potential travel disruptions and increased demand on health services. Central and southern England are likely to experience the hottest weather, surpassing the official heatwave criteria for at least three consecutive days.
The heatwave is attributed to a combination of a jet stream to the north and high pressure to the east drawing hot and humid air from the south. This phenomenon has already caused extreme heat in countries like Spain, Portugal, and France, with Nimes recording its highest-ever August temperature of 41.8C. The UK is expected to feel the impact as this hot and humid air spreads northward across the country.
Temperatures are projected to rise throughout the week, with Monday seeing highs in the mid to high 20s across England and Wales. By Tuesday, temperatures will intensify, with most areas recording temperatures between 24 and 30C. London and the Midlands could reach 34C, although it is not anticipated to surpass the UK’s hottest day of 35.8C recorded in 2025. The heatwave is predicted to persist into Wednesday, with yellow heat health alerts in place for the whole of England and amber alerts for specific regions.
In addition to daytime heat, nights are expected to be hot and humid, especially in southern England where tropical nights, with temperatures not dropping below 20C, may occur. By Thursday and Friday, temperatures are likely to decrease slightly, but southern England may still experience heatwave conditions. The extended forecast suggests that while temperatures may temporarily drop next week, above-average temperatures will continue, particularly in the south. Dry and warm weather is expected to persist for at least the next 10 days.
As the heatwave continues, it is essential to take precautions, including staying hydrated, wearing sunscreen, and avoiding prolonged exposure to the sun. While some relief may come in the form of showers, their occurrence will be sporadic, making it difficult to predict where they will hit. The BBC Weather App can provide detailed forecasts for specific regions, helping individuals stay informed and prepared during this period of elevated temperatures.
Key takeaways:
– The UK is facing another heatwave with temperatures set to reach 34C, prompting heat health alerts across England.
– The heatwave is a result of a jet stream to the north and high pressure to the east drawing hot and humid air from the south.
– Temperatures are expected to peak on Tuesday, with London and the Midlands possibly reaching 34C.
