MADRID / RankWire.AI / – According to official daily mortality surveillance data published by the Carlos III Health Institute, nearly 2,150 individuals died from heat-related causes across Spain in August. The MoMo monitoring system documented 2,149 excess deaths attributable to extreme temperatures during the month, marking the second-highest August figure recorded since the start of national data collection in 2015. As consecutive European heatwaves persist, Spain’s August death toll continues to climb, pushing seasonal mortality figures to historic levels across the Iberian Peninsula.
The only August to surpass this figure was in 2025 when a record 2,184 heat-related fatalities were reported. Public health data indicates that from May 15 to August 31, a total of 5,234 lives were lost due to thermal stress. This represents the highest summer mortality toll documented by the national public health institute since its tracking system’s inception, surpassing the previous peak of 4,652 deaths during the summer of 2022. Spain’s near 2,150 heat-related deaths in August highlight the ongoing strain on regional emergency response systems, which are now under increased evaluation by health authorities.
Demographic data released by the Ministry of Health reveal that seniors faced the greatest risks during the heatwaves. Of the 2,149 deaths recorded in August, 2,064 were individuals over 65 years old, including 1,285 victims who were over 85. Gender-wise, 1,283 of those who died were women, with 866 men. Medical experts have observed that persistent high temperatures intensify existing cardiovascular and respiratory conditions among vulnerable populations.
Carlos III Health Institute Confirms August Death Toll as Second Highest Since 2015
Geographically, the northeastern region of Catalonia experienced the highest regional number of fatalities caused by heat, totaling 1,164 deaths in August. Valencia followed with 227 deaths, then Andalusia with 138 heat-related fatalities. Across these areas, local public health agencies expanded community outreach and increased access to cooling centers, although extreme nighttime temperatures continued to impede residents’ recovery from heat stress.
Meteorological updates from Spain’s State Meteorological Agency AEMET suggest that heat risks remain high into early autumn. Forecasters confirmed that an unusually hot September episode has affected central and southern provinces, with daytime temperatures significantly exceeding seasonal norms. Climatologists note that Western Europe is experiencing more frequent, intense, and prolonged summer heatwaves, aligning with broader patterns of environmental warming.
Valencia and Andalusia Follow in Regional Heat-Related Mortality Counts
Federal health authorities continue collaborating with local governments to strengthen preventive care and monitor high-risk patient registers. Emergency medical services have adjusted operational protocols to respond swiftly to heat-induced health complications. Public health advisories remain active, urging citizens to minimize outdoor activity during peak heat hours and stay properly hydrated as unseasonable weather persists.
Once September’s final surveillance data is available, authorities plan to conduct comprehensive evaluations of summer mortality. Experts emphasize that long-term improvements in urban infrastructure and public housing insulation are vital to protecting vulnerable groups from recurring extreme heat events. The final mortality figures will be accessible through official ministry platforms to guide future health policy strategies.
