- United Kingdom recorded a provisional high of 37.7°C at Lingwood, Norfolk on 27 June, smashing the previous June record of 35.6°C (set in 1976) by a remarkable 2.1°C margin
- Germany reached 41.7°C in Coschen on 28 June, breaking its own all-time record for a third consecutive day, with East Saxony logging the period's highest overnight minimum at 29.4°C
- Netherlands set a new June record with 39.4°C on 26 June, while Hungary recorded an all-time high of 42°C in Szécsény on 30 June
- France endured several days above 40°C, forcing some nuclear power plants to shut down
- Northwestern China is experiencing similarly extreme conditions — 45°C on Monday and 47°C on Tuesday — with extreme heat warnings in the Yuli and Ruoqiang regions expected to continue until 7 July
- A persistent high-pressure system is driving the heatwave by blocking cooler air masses, with authorities warning that road surface temperatures could exceed 60°C and prompting railways to introduce speed restrictions
Why it matters: France's nuclear plant shutdowns prove extreme heat is now a direct threat to power infrastructure, not just a public-health story. Road surfaces forecast above 60°C and rail speed restrictions show transport networks are buckling under conditions that broke records — in the UK's case — by an unprecedented 2.1°C margin. With China's heatwave expected to persist until 7 July, the multi-continent scope signals systemic vulnerability to blocking high-pressure systems.
