Denmark’s meteorological institute recorded 37.0°C in Ødum, the highest since records began in 1874 , and the Czech Republic hit 40.6°C, breaking a 2012 record.

Switzerland recorded its hottest June day ever at 39°C, while Italy and Austria also registered unprecedented highs.

Severe thunderstorms with heavy rain, hail, and strong winds are expected across central Europe by evening, adding to the strain on infrastructure .
With Spain reporting 327 heat-related deaths in a single week , the disaster underscores Europe’s vulnerability to extreme weather. The European Commission has warned that such events are becoming the “new normal,” with June heatwaves now a recurring threat rather than an anomaly.
