Spain recorded 1,029 excess deaths last month that officials attributed to heat, according to data released by the Health Ministry on Wednesday. The figures came as a five-day heatwave, with temperatures surpassing 40 degrees Celsius (104 degrees Fahrenheit), drove June to become the country’s second-hottest month on record.

Data from the Health Ministry’s daily mortality monitoring system, MoMo, showed June had the highest number of deaths attributed to heat since the same month in 2015. Weather agency AEMET said average temperatures in June were 3.2 degrees higher than normal, ranking it second after June 2025.

At the peak of the heatwave on June 23, 35.7 million people—about 73% of Spain’s population—were exposed to health risks from the heat, with 38% facing a high level of risk.

The report also noted that Spain has experienced 12 heatwaves in June since 1975, and that half of them have occurred in the past decade. Between June 1 and June 30, AEMET said local stations broke 165 maximum temperature records (including monthly and all-time highs) and 225 highest minimum temperature records. The agency described the first heatwave of the summer in the north as exceptional not only for intensity but also for its duration and persistence.
