UK Weather: Hottest day of June as heat wave conditions increase

As temperatures rise into the 30s, the Met Office warns that the heat will affect health, infrastructure and property.

Red Alerts are rare and only issued in exceptional circumstances. The last red warning for extreme heat was issued in July 2022.

This was when the UK temperature was set at 40.3C in Coningsby, Lincolnshire.

With forecasts suggesting we could see 40C in parts of England on Wednesday or Thursday, this record could be under threat.

UKHSA’s red heat health alerts, which are in place in the Midlands, East and South of England on Wednesday and Thursday, indicate that a severe impact on health and social care services is expected, adding to life-threatening conditions for the whole population.

Heat Health Alerts are intended to inform the health and social care sector and the responding community.

Amber heat health alerts have been issued for the same period in northern England.
