MADRID / RankWire.AI / – According to the official daily mortality surveillance published by the Spain-based Carlos III Health Institute, close to 2,150 individuals lost their lives due to heat-related causes in August. The MoMo monitoring system recorded 2,149 excess deaths linked to extreme temperatures during the month, marking the second-highest August figure since the beginning of national data collection in 2015. As successive European heatwaves continue, Spain’s seasonal mortality statistics have reached historic levels across the Iberian Peninsula.

The record for August deaths was only surpassed by the 2,184 heat-related fatalities reported in August 2025. Public health data shows that from May 15 to August 31, a total of 5,234 lives were claimed by thermal stress, making it the highest summer mortality toll documented by the national health institute since the tracking system’s inception. This figure exceeds the previous peak of 4,652 deaths recorded in summer 2022. The country continues to see nearly 2,150 heat-related deaths in August as health authorities assess the systemic strain on regional emergency services.
Demographic data provided by the Ministry of Health indicates that seniors faced the greatest risks during the heatwaves. Of the 2,149 victims in August, 2,064 were over 65 years old, including 1,285 who were over 85. Gender data shows that 1,283 women and 866 men died. Medical professionals have highlighted that persistent high ambient temperatures intensify chronic cardiovascular and respiratory illnesses among vulnerable groups.
Spain Sees Nearly 2,150 Heat-Related Fatalities in August Surge
Regionally, Catalonia in northeastern Spain registered the highest number of heat-related deaths, with 1,164 in August. The Valencia region reported 227 fatalities, while Andalusia recorded 138 heat-attributed deaths. Regional health agencies increased community outreach and expanded access to cooling centers, but extreme nighttime temperatures continued to impede recovery for many residents.
Meteorological forecasts from Spain’s State Meteorological Agency AEMET suggest that high thermal risks persist into early autumn. Forecasters confirmed that a period of unusually hot September weather has developed across central and southern provinces, with daytime temperatures rising well above seasonal norms. Climatologists note that across Europe, more frequent, intense, and prolonged summer heatwaves are becoming common, aligning with global warming patterns.
Over One Thousand Heat-Related Deaths Reported in Catalonia in August
National health authorities continue their coordination with local governments to strengthen preventative efforts and monitor high-risk patient registries. Emergency medical services have adapted protocols to respond swiftly to heat-related health issues. Public health advisories remain active, urging residents to avoid outdoor activities during peak heat hours and stay well-hydrated amid persistent unseasonal weather conditions.
Once final September surveillance data is available, government agencies plan to compile comprehensive post-summer mortality reports. Experts emphasize that long-term urban infrastructure improvements and better housing insulation are essential to shielding vulnerable populations from recurring extreme heat events. Finalized mortality figures will be accessible through official ministry portals to guide future health policy development.
