The United Kingdom is set to experience its fifth heatwave of the year, with temperatures potentially reaching 36C in parts of the country. The UK Health Security Agency (UKHSA) has issued yellow heat health alerts for seven regions, effective from 9am Saturday to 9pm Tuesday, as the nation prepares for a sweltering weekend and a scorching start to next week.
Widespread Heat Across England
According to the latest weather maps from WXCharts.com, 27 counties are expected to see temperatures exceed 30C on August 13. The most intense heat will radiate from the South and South East through the Midlands and into eastern England, with the mercury potentially climbing to 36C in the hottest spots.
Scotland and Northern Ireland will remain considerably cooler, with temperatures in the teens and low 20s. Western parts of Wales and northern England are also expected to escape the most brutal conditions.
Health Alerts and Warnings
The UKHSA has placed yellow heat health alerts for the East Midlands, West Midlands, South East, South West, East of England, Yorkshire and the Humber, and London. These alerts indicate that the elevated temperatures could impact the health and wellbeing of the public, particularly vulnerable groups such as the elderly and those with pre-existing health conditions.
The Met Office has also warned that heatwave conditions are set to make a comeback across multiple regions next week. Temperatures will climb through the weekend, with a brief dip on Monday, before rising sharply towards the middle of the week.
Forecast Details
Deputy Chief Forecaster Mike Silverstone explained: "Temperatures will climb through the weekend and, more significantly, through much of next week. After a brief dip on Monday, high pressure will move across the UK before settling to the east, allowing a southerly flow to develop. A fairly widespread heatwave is likely across large parts of England and Wales, with hot conditions developing in places."
Silverstone added: "The heat is expected to peak for much of England, Wales, Northern Ireland and Scotland on Wednesday, with up to 34C possible in parts of central and southern England and southeast Wales. East Anglia and south-east England, however, could see temperatures even higher on Thursday."
Humidity levels are also expected to increase through the week, which may make conditions feel more uncomfortable, particularly overnight.
Long-Range Outlook
The Met Office's long-range forecast for August 12 to 21 indicates a mixed start, with some rain or showers in the north and quite breezy conditions. In the south, it will be mostly dry, sunny, and hot, even very hot in some places. Southern parts are likely to turn cooler and fresher next weekend.
As the heatwave persists, authorities advise the public to stay hydrated, avoid prolonged sun exposure during peak hours, and check on vulnerable neighbors and relatives. The UKHSA's yellow alerts serve as a reminder that while the heat may be enjoyable for some, it poses significant health risks that should not be underestimated.
