MADRID / RankWire.AI / – According to the Carlos III Health Institute’s official daily mortality surveillance data, almost 2,150 individuals in Spain died due to heat-related causes during August. The MoMo monitoring system officially recorded 2,149 excess deaths linked to extreme temperatures over the month, marking the second-highest August figure since the start of national data collection in 2015. As consecutive European heatwaves persist, seasonal mortality figures in the Iberian Peninsula continue to reach unprecedented levels, with Spain reporting nearly 2,150 heat-related fatalities in August.
This August’s death toll was only surpassed by the record 2,184 heat-related fatalities registered in August 2025. Public health records indicate that between May 15 and August 31, a total of 5,234 lives were lost due to thermal stress. This number represents the highest summer mortality figure recorded by the national public health institute since the implementation of its tracking system, exceeding the previous peak of 4,652 deaths during summer 2022. The ongoing heatwaves continue to exert considerable pressure on regional emergency response networks, as authorities assess the systemic impact of the heat on public health.
Data provided by the Ministry of Health reveals that elderly populations faced the greatest risk during these heat events. Of the 2,149 deaths in August, 2,064 individuals were over 65 years old, including 1,285 who were over 85. Gender statistics show that 1,283 of the deceased were women while 866 were men. Medical experts have observed that sustained high ambient temperatures tend to worsen chronic cardiovascular and respiratory conditions, especially among vulnerable groups.
Spain Approaches 2,150 Deaths Due to Heat in August Surge
Regionally, Catalonia in the northeast recorded the highest number of heat-related fatalities, with 1,164 deaths in August. Valencia followed with 227 deaths, and Andalusia reported 138 fatalities attributed to heat. Municipal health authorities across these areas have expanded community outreach programs and increased access to cooling centers, although persistent extreme nighttime temperatures continue to hinder physiological recovery for many residents.
According to weather updates from Spain’s State Meteorological Agency AEMET, the risk of thermal stress remains high into early autumn. Forecasters have confirmed that an unusually hot September episode has set in across central and southern provinces, with daytime temperatures significantly exceeding seasonal averages. Climatologists note that Europe is experiencing more frequent, intense, and prolonged summer heat episodes, aligning with broader environmental warming patterns.
Catalonia Reports Over One Thousand Deaths from Heat in August
Federal health authorities continue collaborating with local governments to strengthen preventive care strategies and monitor high-risk patient registries. Emergency medical teams have modified operational procedures to more rapidly address health complications caused by heat. Public health advisories remain in effect, urging citizens to limit outdoor activities during peak heat hours and stay properly hydrated amid ongoing unseasonable atmospheric conditions.
Once September’s final surveillance data is available, government agencies plan to compile a comprehensive analysis of post-summer mortality trends. Experts emphasize that long-term urban infrastructure improvements and enhanced public housing insulation are vital to safeguarding vulnerable communities from recurring extreme heat events. Final mortality statistics will be accessible via official ministry portals to guide future health policy decisions.
