A severe heatwave in June 2026 has caused more than 3,500 excess deaths across France, Belgium, and the Netherlands. This extreme weather put heavy pressure on hospitals, disrupted daily life, and hit older people the hardest. France reported the highest number of extra deaths, while Belgium called the situation unprecedented.
Temperatures soared to record levels in many areas, with some places reaching over 40°C. The heat affected healthcare services, caused power problems, and led to more emergency calls. Many people, especially the elderly, faced serious health risks from high temperatures and poor air quality.
Experts link the intense heat to climate change, which is making such events more common and stronger in Europe. The final death toll may still rise as more data comes in from different regions.
Authorities in the affected countries urged people to stay indoors during the hottest hours, drink plenty of water, and check on elderly family members. Governments also opened cooling centres and gave special advice to protect vulnerable groups.
