Spain’s 2026 heat mortality reaches historic peak
Spain recorded 5,232 heat-related deaths in 2026, the highest number since the MoMo surveillance system of the Carlos III Health Institute began keeping these statistics in 2015. The figures cover the period starting May 15 and show the severe impact of unusually hot weather on the population. August alone has a preliminary count of 2,147 such deaths, while July accounts for another 2,025. These numbers add to growing evidence that extreme heat is becoming a greater public health threat across Europe.
How the 2026 summer compares with earlier years
The 2026 totals surpass the summer readings of 2022 and 2023, when there were 4,789 and 3,035 heat-related deaths respectively. Among the 5,232 deaths, 5,048 were people aged 65 or older, and 62% of that group — 3,256 individuals — were above 85 years of age. Around 60% of those who died were women. It is important to note that MoMo provides a statistical estimate of how many deaths are associated with high temperatures, rather than documenting heat as the direct cause on each death certificate.
July 2026 tied with July 2022 as Spain’s hottest month in recorded history, and June 2026 was the second hottest June on record. France also faced serious consequences from the same heat episode, reporting more than 7,300 deaths since the start of the summer. The hottest days ever measured in France were June 24 and 25, 2026, when the national average daily temperature reached 30°C.
These findings highlight the growing impact of climate change on human health, especially for older people, who are most vulnerable to extreme temperatures. Comparisons with previous years suggest that abnormal weather events are happening more often, which means governments and healthcare systems may need to pay greater attention to protecting residents. Studying how different countries respond to rising temperatures, as the situation in neighboring France shows, will also be essential for adapting to a warming climate.
The alarming statistics from Spain are part of a broader trend across Europe, where extreme heat has led to significant loss of life. A recent report highlights that over 25,000 people have died during Europe's hottest summer on record. This raises urgent questions about public health responses and climate adaptation strategies as the frequency of such weather events increases.
