The United Kingdom is currently experiencing its third heatwave of the year, with temperatures anticipated to climb as high as 34C (93.2F) by mid-week. This heat event, while not expected to match the peak temperatures of 37.7C (100F) recorded in late June, is forecast to last for a more extended period.
Yellow heat-health alerts have been issued by the UK's Health Security Agency (UKHSA) for the Midlands and southern England, effective until 8:00 PM GMT on July 11. These alerts indicate potential minor impacts on health and social care services, with a heightened risk to vulnerable populations.
Northern regions of the UK will experience warmer conditions, though cloud and rain are likely to persist, particularly in western Scotland. On Monday afternoon, temperatures in the Midlands, East Anglia, and southeast England could reach 31C (87.8F), meeting the official heatwave criteria of temperatures above 28C (82.4F) in these areas for several consecutive days.
The heatwave is projected to intensify from mid-week, with temperatures across England and east Wales expected to range from the high 20s to low 30s Celsius. London and southeast England are forecast to see the highest temperatures, potentially peaking around 34C (93.2F) on Wednesday and Thursday.
While current forecasts suggest it is unlikely to surpass the all-time UK record of 40.3C (104.5F) set in July 2022, some weather models indicate a possibility of temperatures reaching the mid to high 30s Celsius this week. The UKHSA's alerts underscore the potential risks associated with prolonged high temperatures, particularly for those with pre-existing health conditions.
