UK braces for another heat spell as health alerts extend across England and Wales

A prolonged dry spell has left much of England and Wales without rain, prompting the UK Health Security Agency to issue yellow heat health alerts for large parts of the country through early August.

England and Wales are experiencing an extended period of dryness, with Wisley in Surrey reaching 50 consecutive rain-free days, eclipsing the 1976 record of 36 days. July marked the driest month on record for the two nations since the Met Office began keeping data. A persistent high-pressure system is preventing cloud formation, limiting rainfall to a scant 6.5 mm in England and 9.3 mm in Wales, while Scotland and Northern Ireland see occasional showers.

The UK Health Security Agency has activated yellow heat health alerts for the Humber, West and East Midlands, east of England, London, and the South East and South West from Saturday morning until Tuesday night, as temperatures are expected to climb back into the high 20s to low 30s Celsius, with a potential mid-30s surge later in the week. The agency cautions that vulnerable populations may see higher demand for health services and that indoor overheating and water-related hazards could increase. Despite some rain in northern areas, the south remains in drought, leading a water supplier in Essex and Suffolk to ban hosepipe use, and no significant rainfall is forecast to end the dry spell soon.
