Overview
- Roughly 193 million people in Europe have faced temperatures above 35°C during the late-June event, with many local records topped including readings above 41°C in Germany.
- National reporting shows mounting mortality: Santé publique France recorded about 1,000 excess deaths since the heat began on 24 June and the World Health Organization reported roughly 1,300 heat-linked deaths in about a week.
- Model-based estimates using the Masselot method and city temperature data project up to about 12,000 excess deaths across Europe for the three-day period of 24–26 June, a figure that differs from and exceeds real-time official counts.
- The heatwave is disrupting infrastructure now with localized blackouts from grid overload, rail delays from track deformation, stress on river cooling for French nuclear plants and rising household energy costs for cooling.
- Forecasts show the high-pressure dome starting to break from around 29 June with a likely short-lived cool-down and a risk of violent thunderstorms, but scientists warn the event reflects a warmer baseline that makes further heat episodes more likely and call for long-term adaptation measures.
