Monday’s sweltering conditions are expected to be replicated on Tuesday, as forecasters warn that slightly warmer air at lower levels could drive temperatures even higher.
Regional Forecasts and Potential Storms
The highest temperatures are anticipated in south-east England, while other areas across England and Wales are expected to climb into the high 20s. While most regions will remain dry and sunny, an increase in atmospheric moisture may lead to thunderstorms across southern England, East Anglia and potentially around Yorkshire.
In the north of England, fewer locations are expected to see extreme temperatures compared to the levels recorded on Monday.
Record-Breaking Trends and Heat Alerts
This period of intense heat highlights a notable trend in weather patterns. According to the Met Office, more than half of the monthly record highs—seven out of 12—have been set since 2003.
Met Office chief operational meteorologist Dan Suri attributed these exceptionally high temperatures to “the influence of warmth building under an area of high pressure near the UK.” These readings are significantly above the typical end-of-May average of 14-20C.
Health authorities are already on alert. On Friday, the UK Health Security Agency issued its first amber-heat health alert of 2026. This alert covers much of England, including the West Midlands, East Midlands, East of England, South East, and London.
yellow alerts have been issued for the North East, North West, South West, Yorkshire, and Humber regions. Both the amber and yellow alerts are scheduled to remain in place until 17:00 BST Wednesday.
