UK Heat Dome: Amber Alert Issued for Extreme Heat
22 Jun
Summary
- Amber heat warning issued for parts of UK starting Monday.
- Temperatures may reach mid-thirties across southern areas.
- Heat dome phenomenon trapping hot air over Europe explained.
The Met Office has issued an amber weather warning for extreme heat across the South West, South East, East of England, and parts of South Wales, active from Monday, June 24, 2026, until the end of Tuesday, June 25, 2026. Forecasters anticipate temperatures could climb into the mid-thirties Celsius in the UK.
This developing heatwave is attributed to a 'heat dome,' a high-pressure system over Europe trapping warm air. While southern and eastern parts of the UK are expected to swelter, cooler weather fronts may bring rain to northern and western areas. Similar heat dome conditions are causing temperatures to soar across continental Europe, with Spain, France, and Italy expecting highs in the mid-thirties to potentially over 40C.
