Met Office Issues Red Heat Warning as UK Approaches Hottest June Day on Record

The Met Office issued its highest-tier Red Heat Warning on 24 June, valid from 09:00, as peak temperatures around 39°C are forecast for southern England on Wednesday and Thursday. The June UK record—35.6°C, set in 1976—sits directly in range. A 34.6°C reading in Surrey on Tuesday preceded this escalation. The warning reflects near-certain population-wide health and infrastructure impacts.
