Recent data released by the Carlos 3º Health Institute, located in Madrid, indicate that at least 212 deaths in Spain, which occurred between last Sunday (21) and Wednesday (24), may be related to the strong heat wave that hit the territory in recent days. Authorities are now investigating the exact impact of these high temperatures on the health of the population.
These estimates are calculated through MoMo (Mortality Monitoring), a system that daily collects information on the number of deaths in Spanish territory. It calculates the divergence between observed and expected mortality, based on historical records, offering an overview of atypical events. MoMo is essential for the rapid response of public health policies, allowing the identification of spikes in deaths associated with specific factors, such as extreme weather phenomena.
High temperature records for the month of June
For its analyses, the MoMo system also considers temperature data released by the State Meteorological Agency (Aemet).
As of Thursday (25), no area in Spain was under orange or red alerts for heat, according to Aemet statements.
Last Monday (22) Spain experienced an average of 28.17°C and, on Tuesday (23), 28.08°C. These were the hottest days for the month of June recorded in the country since 1950, according to information from Aemet. The recurrence of these records highlights a worrying trend of rising average temperatures.
The previous year, June 2025 had already been recognized as the hottest ever documented, according to the Spanish meteorological agency. The country’s Ministry of Health reported that in the period from May 16 to September 30, 2025, a total of 3,832 deaths were officially attributed to extreme heat conditions.
Spain, one of the European countries most affected by climate change, already has a history of high temperatures. However, in recent years, the country has faced a notable intensification in heat waves, which have become more frequent and with shorter intervals during the summer season.
