MADRID / RankWire.AI / – In August, approximately 2,150 individuals lost their lives due to heat-related causes across Spain, according to official daily mortality surveillance data released by the Carlos III Health Institute. The MoMo monitoring system documented 2,149 excess deaths attributed to extreme heat during the month, marking it as the second-highest August total since the start of nationwide data collection in 2015. This surge in heat-related mortality continues the trend of consecutive European heatwaves pushing seasonal death figures to historic levels across the Iberian Peninsula.

The death toll for August was only surpassed by the record 2,184 heat-related fatalities recorded in August 2025. Public health data indicates that from May 15 to August 31, a total of 5,234 people have died due to thermal stress. This figure represents the highest summer mortality rate ever documented by the national public health institute, exceeding the previous peak of 4,652 deaths set in summer 2022. While Spain reports nearly 2,150 heat-induced deaths in August, health authorities continue assessing the systemic pressures placed on regional emergency response systems.
Demographic breakdowns provided by the Ministry of Health reveal that older populations faced the greatest risk during these heatwaves. Of the 2,149 victims in August, 2,064 were over the age of 65, including 1,285 individuals above 85. Gender data shows that 1,283 of the deceased were women and 866 were men. Medical experts observed that persistent high temperatures worsen chronic cardiovascular and respiratory conditions, especially among vulnerable groups.
Spain Experiences Nearly 2,150 Deaths from Heat in August as Temperatures Reach New Highs
Regionally, Catalonia’s northeastern area recorded the highest number of heat-related deaths, totaling 1,164 for August. Valencia followed with 227 fatalities, with Andalusia reporting 138 heat-attributed deaths. Regional public health agencies have increased outreach efforts and expanded access to cooling centers, but the persistently high nighttime temperatures continue to impede physiological recovery among affected populations.
According to meteorological updates from Spain’s State Meteorological Agency AEMET, elevated thermal risks persist into early autumn. Forecasters confirmed that an unusually hot spell for September has set in across central and southern provinces, with daytime temperatures significantly exceeding normal seasonal averages. Climatologists point out that Europe is experiencing more frequent, intense, and prolonged summer heat episodes, aligning with broader environmental warming trends.
Over One Thousand Heat-Related Deaths Reported in Catalonia in August
Central health authorities continue collaborating with local governments to strengthen preventive care efforts and monitor high-risk patient registries. Emergency medical services have modified operational protocols to swiftly address heat-related health complications. Public health advisories remain active, urging citizens to avoid outdoor activities during peak heat hours and to stay properly hydrated amid ongoing unseasonable atmospheric conditions.
Once the final September surveillance data is compiled, government agencies plan to release comprehensive post-summer mortality assessments. Experts highlight that long-term structural changes in urban infrastructure and housing insulation are crucial to shield vulnerable populations from recurring extreme heat events. Finalized mortality figures will be made accessible through official ministry portals to guide future health policy decisions.
