Summary
An omega blocking pattern is holding a heat dome over Western Europe into a sixth day. Météo-France recorded France's highest nationally averaged daily temperature ever on 24 June (29.8C nationally; 44.3C locally at Pissos in southwestern France), surpassing the 2019 record. Spain's public health institute counted 212 heatwave-linked deaths between Sunday and Wednesday. In France, approximately 48-50 people have died in total, most from drowning in rivers and lakes, with two children killed in hot cars. Britain logged 36.1C in southern England, the highest June temperature in UK records. Around 38,500 homes remain without electricity after a heat-damaged transformer failed in Finistere. Red alerts span France, Spain, Germany, Austria, Switzerland and Luxembourg.
Why it matters
Météo-France has explicitly compared conditions to the 2003 heatwave that killed nearly 15,000 in France. The EU Grid is under peak summer load precisely as AI data-centre power demand runs at its seasonal maximum; demand-response measures are already active in France and Germany. Agricultural heat stress during the grain and wine ripening phase will affect autumn harvest yields.
What to watch
- Whether the omega blocking pattern persists beyond the current red-alert window ending Friday midday
- EU Grid stability under combined domestic cooling load and AI-sector demand
- Cumulative death toll across Spain and France, which will inform the EU's revision of its heat-emergency protocols
