Overview
- France's public health agency reported roughly 1,000 excess deaths during the peak June 24–26 period and warned the toll is likely to rise as deaths in homes and care facilities are fully recorded.
- Meteorological services across Europe recorded new highs over the weekend, including preliminary national records in Germany (41.5°C), the Czech Republic (~40.6–40.9°C) and Denmark (~37°C).
- A rapid attribution study by World Weather Attribution found the intensity of the heat and humidity would have been virtually impossible without human-driven climate change, greatly increasing the event's likelihood.
- The heat stressed services and infrastructure: rail and tram services were cancelled or restricted, highways and track materials buckled, hospitals reported saturation, and Hungary warned the Paks nuclear plant may need to cut output because the Danube is too warm for cooling.
- The immediate response has included water cannons in Berlin, alcohol and event restrictions in Paris, school closures and emergency funding for hospitals, while public debate grows over short-term protections and longer-term cooling and resilience investments.
