Spain Records Over 1,000 Heat-Related Deaths in Second Hottest June

Spain recorded 1,029 deaths attributed to heat last month, according to official data released today.

These are deaths believed not to have occurred without the extreme temperatures.

Data from the Ministry of Health’s daily mortality monitoring system (MoMo) show that this June saw the highest number of heat-related deaths since the same month in 2015.

Average temperatures last month were 3.2 degrees higher than usual, the meteorological agency AEMET reported, making June the second hottest ever, just behind June 2025.

At the peak of the heatwave, on June 23, 35.7 million people, or about 73 percent of the country’s population, were exposed to health risks due to the heat.

Since 1975, there have been 12 heatwaves in June, with half occurring in the last ten years.

All 13 hottest Junes since records began in 1961 have occurred in the 21st century.

“This is evidence that heatwaves are occurring at the start of summer with greater frequency than before,” said AEMET spokesperson Ruben del Campo.

Between June 1 and 30, 165 records for maximum temperatures and 225 records for highest minimum temperatures were broken at local measuring stations, AEMET reported, according to Reuters.
