Summary
Temperatures are set to climb to 34C in London and south-east England by Wednesday and Thursday, marking the UK's third heatwave of 2026 after highs near 31C on Monday.
Yellow heat-health alerts cover the Midlands and southern England until 20:00 GMT on 11 July, with officials warning of minor strain on health and social care services and higher risks for vulnerable people.
This spell is expected to last longer than late June's heatwave, even if it falls short of that event's 37.7C peak; forecasts suggest 30C could be exceeded somewhere in the UK for up to 10 straight days.
The heat is being driven by a broader European surge that has already pushed Porto to 40.1C, with France also bracing for mid-to-high 30s and some areas above 40C.
