The UK is expected to experience another heatwave from mid-August, with temperatures forecast to reach up to 37°C in parts of England and Wales, following several weeks of rain, cooler conditions, and thunderstorms. Forecast data points to a sharp rise in temperature beginning around Saturday, August 16, particularly across central and western regions.
According to information reported by GloucestershireLive, areas including Gloucestershire, Warwickshire, and North Wales could be among the most affected. While the full scope of the heatwave is still being monitored, preliminary indicators suggest that large portions of the UK may be impacted by unusually high temperatures.
Intense Heat Set to Return From August 16
Weather models from WXCharts, using MetDesk data, indicate that a significant rise in temperatures is likely to begin on Saturday, August 16. Maps show a dark red color, often associated with extreme heat events, spreading across southern and central parts of the UK.
The most affected areas could include Gloucestershire, Warwickshire, Worcestershire, and North Wales, where forecasts point to highs reaching 37°C. If confirmed, this would make it the hottest UK day since the 2022 heatwave, which set a national record at 40°C.
Widespread Regional Heat With Distinct Temperature Bands
The incoming heatwave is expected to cover much of England and Wales, but with regional variations. The South West will experience high temperatures in cities such as Bristol and Bath, where maximums of 33°C are forecast.
In West and Mid Wales, temperatures are likely to reach 32°C, while the East and West Midlands could see a range from 33°C to 36°C. Yorkshire and the Humber region are also expected to reach 33°C.
Further southeast, areas such as Kent, London, and Surrey could register up to 34°C, and coastal cities including Brighton and Portsmouth are expected to see temperatures of 33°C.
Cooler Conditions in Scotland and Northern Ireland
In contrast to the areas most impacted by the heat, Scotland and Northern Ireland are projected to remain significantly cooler. Highs will likely stay in the low to mid-20s°C, highlighting a north-south divide typical of UK heatwave patterns.
Recent Weeks Marked by Unsettled Conditions
The forecast comes after several weeks of unseasonably wet and cool weather across the UK. These conditions included frequent rain showers, mild daytime highs, and intermittent thunderstorms in both urban and rural areas. This prolonged period of instability sets the stage for what could be a sharp meteorological contrast.
Day-By-Day Forecast for the South West
The Met Office has provided a more detailed short-term outlook for the South West of England, which serves as a lead-up to the projected heatwave:
- Tuesday: Breezy conditions with a mixture of sunny spells and isolated showers. The day will feel noticeably fresher due to northwesterly winds, with a maximum temperature of 22°C.
- Wednesday: The region will see drier and warmer conditions, with plenty of sunshine, although skies may appear hazy at times.
- Thursday: A return of cloudier skies and breezy conditions, with patchy rain expected.
- Friday: Rain will likely clear to leave brighter skies and an increase in temperatures, setting the stage for the onset of the heatwave over the weekend.
Monitoring Needed as Extreme Heat Approaches
While official heatwave alerts have not yet been issued by the Met Office, the combination of high temperatures, recent unstable weather, and visual indicators from forecast models suggests that conditions may rapidly intensify.
Should the forecasted 37°C readings materialize, public health services and local councils may implement preventative measures, particularly to protect vulnerable populations such as the elderly, infants, and those with underlying health conditions.
The UK’s increasing vulnerability to heatwave events has prompted ongoing discussions about infrastructure resilience and urban planning adaptations, particularly in light of the record-breaking summer of 2022.
