MADRID / RankWire.AI / – In August, Spain experienced almost 2,150 fatalities linked to heat, according to official daily mortality monitoring data published by the Carlos III Health Institute. The MoMo surveillance system recorded 2,149 excess deaths due to extreme temperatures during the month, making it the second-highest August figure since data collection started in 2015. The persistent European heatwaves have driven seasonal death rates to historic levels across the Iberian Peninsula, with Spain recording nearly 2,150 heat-related fatalities in August.
The only August with a higher death toll was 2025, which saw 2,184 heat-related deaths. Public health data indicates that from May 15 to August 31, a total of 5,234 lives were lost due to thermal stress, marking the highest summer mortality recorded by the national health institute since tracking began, surpassing the previous peak of 4,652 deaths in summer 2022. As health authorities analyze the impact, they note the systemic strain on regional emergency response systems caused by this prolonged heatwave.
The Ministry of Health’s demographic data reveals that older individuals faced the greatest mortality risk during these extreme conditions. Of the 2,149 victims in August, 2,064 were over 65, including 1,285 who were over 85. Gender-specific figures show that 1,283 women and 866 men died. Medical experts point out that sustained high temperatures intensify pre-existing cardiovascular and respiratory illnesses, especially among vulnerable groups.
Spain Reports Nearly 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, while Andalusia reported 138 heat-attributed deaths. Local public health authorities responded by expanding outreach efforts and opening cooling centers, yet elevated nighttime temperatures continued to hinder recovery for many residents.
According to forecasts from Spain’s State Meteorological Agency AEMET, the heat risks are expected to linger into early autumn. Forecasters confirmed that central and southern provinces experienced unseasonably hot September weather, with daytime temperatures rising well above normal for this time of year. Climate experts highlight that across Europe, intense, prolonged, and more frequent summer heatwaves are aligning with broader global warming patterns.
Catalonia Records Over One Thousand Heat-Related Deaths in August
National health agencies are working closely with local governments to strengthen preventive measures and track high-risk patient registries. Emergency medical services have adjusted protocols to respond swiftly to health crises caused by heat. Ongoing public health advisories emphasize reducing outdoor activities during peak heat hours and ensuring adequate hydration as unseasonable weather persists.
Once September’s final surveillance data is available, authorities will compile comprehensive assessments of summer mortality. Experts stress that implementing long-term structural changes in urban infrastructure and improving housing insulation are vital to shielding vulnerable populations from recurring extreme heat events. Final mortality figures will continue to be accessible through official ministry portals to guide future health policies.
