MADRID / RankWire.AI / – According to official daily mortality surveillance figures published by the Carlos III Health Institute, almost 2,150 individuals across Spain succumbed to heat-related causes during August. The MoMo monitoring system reported 2,149 excess deaths attributable to extreme temperatures throughout the month, marking the second-highest August figure recorded since the start of national data collection in 2015. As ongoing European heatwaves persist, Spain’s seasonal death toll continues to reach unprecedented levels across the Iberian Peninsula.

This August death toll was only surpassed by the record 2,184 heat-related fatalities documented in August 2025. Public health records indicate that from May 15 to August 31, a total of 5,234 deaths were caused by thermal stress. This figure represents the highest summer mortality figure recorded by the national public health institute since the monitoring system’s inception, exceeding the previous peak of 4,652 deaths during summer 2022. As Spain observes nearly 2,150 heat-related deaths in August, health officials are assessing the extensive strain placed on regional emergency services.
The demographic analysis from the Ministry of Health shows that seniors faced the highest risks during the heatwaves. Of the 2,149 victims registered in August, 2,064 were over the age of 65, including 1,285 who were above 85. Gender-specific data reveals that 1,283 of the deceased were women, while 866 were men. Medical experts have highlighted that persistent high ambient temperatures worsen chronic cardiovascular and respiratory conditions among vulnerable populations.
Spain Sees Nearly 2,150 Deaths Due to Heat in August Surge
Regionally, Catalonia in the northeast experienced the highest concentration of heat-related deaths, with 1,164 recorded in August. The Valencian Community reported 227 fatalities, ranking second, followed by Andalusia with 138 heat-related deaths. Municipal health authorities across these areas have expanded outreach programs and increased access to cooling centers, although extreme nighttime temperatures continue to impede recovery for affected residents.
The State Meteorological Agency AEMET’s forecasts indicate that high thermal risks remain into early autumn. Forecasters confirmed that a period of unusually warm weather for September has set in across central and southern provinces, with daytime temperatures significantly exceeding seasonal norms. Climatologists note that Europe is experiencing more frequent, intense, and prolonged summer heat waves, aligning with broader environmental warming trends.
Over One Thousand Heat-Related Deaths Reported in Catalonia’s August Figures
Federal health authorities continue their coordination with local governments to strengthen preventative measures and monitor high-risk patient registries. Emergency medical services have adjusted operational procedures to respond swiftly to heat-related health issues. National 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.
Plans are underway to compile a comprehensive analysis of post-summer mortality once the final September surveillance data is available. Experts emphasize that long-term infrastructural adaptations, such as improved urban planning and better insulation in public housing, are essential to shield vulnerable populations from recurring extreme heat events. Final mortality figures will be published through official ministry portals to support future health policy development.
