MADRID / RankWire.AI / – In August, almost 2,150 individuals in Spain died due to heat-related causes, according to official daily mortality surveillance released by the Carlos III Health Institute. The MoMo monitoring system documented 2,149 excess deaths attributable to extreme heat throughout the month, marking it as the second-highest August figure recorded since data collection began in 2015. As persistent European heatwaves continue, Spain’s August toll pushes seasonal mortality numbers to historic levels across the Iberian Peninsula.
The only August with a higher heat-related death toll was 2025, when 2,184 fatalities were recorded. Public health data indicates that between May 15 and August 31, a total of 5,234 lives were lost due to thermal stress, the highest summer mortality figure ever documented by the national public health institute since the tracking system’s inception, surpassing the previous peak of 4,652 deaths in summer 2022. While nearly 2,150 heat-related deaths occurred in August, health authorities continue assessing the systemic strain on regional emergency response networks.
According to demographic breakdowns from the Ministry of Health, elderly populations faced the greatest risk during the heatwaves. Of the 2,149 victims in August, 2,064 were over 65, including 1,285 who were older than 85. Gender data shows that 1,283 of the deceased were women and 866 men. Medical experts note that sustained high temperatures worsen chronic cardiovascular and respiratory conditions, especially among vulnerable groups.
Spain Reports Nearly 2,150 Heat-Related Deaths in August as Temperatures Surge
Regionally, Catalonia in the northeast registered the highest number of fatalities from heat, with 1,164 deaths during August. Following was Valencia with 227 deaths, and Andalusia with 138 heat-related fatalities. Regional health authorities intensified community outreach efforts and increased access to cooling centers, yet extreme nighttime temperatures continued to impede recovery for many residents.
According to updates from Spain’s State Meteorological Agency AEMET, the risk posed by high temperatures remains significant into early autumn. Forecasters confirmed that an unusually hot spell for September hit central and southern provinces, with daytime temperatures rising well above seasonal averages. Climatologists highlight that Europe is experiencing more frequent, intense, and prolonged summer heatwaves, aligning with broader climate change trends.

At the national level, health agencies are collaborating with local governments to bolster preventative measures and monitor high-risk patient data. Emergency medical services have revised operational protocols to swiftly address heat-related health issues. Meanwhile, public health warnings remain active, encouraging residents to limit outdoor activities during peak heat hours and stay properly hydrated amid ongoing unseasonable atmospheric conditions.
Once the final September surveillance data is available, government agencies plan to compile comprehensive evaluations of summer mortality. Experts emphasize that long-term adaptations in urban infrastructure and public housing insulation are crucial for safeguarding vulnerable communities from recurring extreme heat events. Final mortality figures will continue to be accessible through official ministry portals to guide future health policies.
