Europe moves into early heat emergency footing after record May temperatures

Last updated May 30, 2026

• Earlier emergency activation shows climate adaptation is becoming a routine governance function rather than an exception.
• Public-health transmission chain.
• Italy issued a red alert for Rome on Thursday as France, Portugal and the UK reported record May heat, according to France 24 and The Guardian.
• The heat arrived unusually early, with a high-pressure “heat dome” pushing temperatures across parts of Europe far above seasonal norms.
• The Guardian reported that the UK reached 35.1C at Kew Gardens in London on Tuesday, breaking a May record that had been set only the day before at 34.8C.
