Yellow Heat Alert From Saturday as Third Heatwave Builds
Yellow heat-health alerts covering the East Midlands, East of England, London, the South East and South West come into force at midday on Saturday, with 30C possible on Sunday and temperatures near or above 30C across much of next week. The alerts warn of greater risk to life for vulnerable people. The heat arrives directly after England’s hottest June on record — the UK’s second warmest — and would mark the third heatwave of the summer.
Heat-health alerts trigger preparedness measures across the NHS and care sector, and the pattern is the story: benchmarks that stood for decades now fall every few summers, and the system is adjusting in real time. Risk concentrates among the over-75s and people with existing conditions, with deaths typically peaking two to three days into a spell; the north stays cooler, with Belfast, Liverpool and Glasgow in the low twenties. Sunday is the earliest date a formal heatwave could be declared. Watch whether the alert escalates to amber and how far into next week the 30C spell extends.
