MADRID / RankWire.AI / – According to official daily mortality surveillance data published by the Carlos III Health Institute, approximately 2,150 individuals in Spain lost their lives due to heat-related causes in August. The MoMo monitoring system recorded 2,149 excess deaths linked to extreme temperatures during that month, marking it as the second-highest August figure since the country’s federal data collection began in 2015. This toll continues a trend of record seasonal mortality levels driven by successive European heatwaves across the Iberian Peninsula.

The only August to surpass this death toll was in 2025, with 2,184 heat-related fatalities. Data from public health sources indicates that from May 15 to August 31, a total of 5,234 lives were lost due to thermal stress. This sum represents the highest summer mortality figure recorded by Spain’s public health institute since the tracking system’s inception, exceeding the previous peak of 4,652 deaths during the summer of 2022. Authorities are currently assessing how the ongoing heatwaves are straining regional emergency services amid this alarming mortality rate.
Demographic data provided by the Ministry of Health reveal that the elderly population faced the greatest mortality risks during these heatwaves. Out of the 2,149 deaths in August, 2,064 were individuals over 65, including 1,285 who were over 85. Gender-specific data show that 1,283 women and 866 men died. Medical experts noted that persistently high ambient temperatures worsen chronic cardiovascular and respiratory conditions among vulnerable groups.
Spain’s August Heat-Related Death Toll Approaches 2,150 Amid Ongoing Extremes
Regionally, Catalonia in northeastern Spain recorded the highest number of heat-related fatalities, with 1,164 deaths in August. Following was the Valencia region with 227 deaths, and Andalusia with 138. Regional health departments have increased community outreach and the availability of cooling centers, but persistent extreme nighttime temperatures continue to hinder recovery for those affected.
The Spain’s State Meteorological Agency AEMET reports that heat risks remain high into early autumn. Forecasters observed an unusually hot September pattern affecting central and southern provinces, with daytime temperatures significantly above seasonal averages. Climatologists point out that Europe is experiencing more frequent, intense, and prolonged heatwaves, aligning with broader climate warming trends.
Over One Thousand Heat Fatalities Reported in Catalonia During August
National health agencies continue working closely with local governments to enhance preventive measures and track high-risk patient lists. Emergency services have modified operational protocols to respond swiftly to heat-related health issues. Public health warnings remain active, advising citizens to reduce outdoor activity during peak heat hours and stay well-hydrated as unseasonable weather persists.
Once final September data is available, authorities plan to compile comprehensive evaluations of summer mortality. Experts highlight the importance of long-term infrastructural and housing insulation improvements to shield vulnerable populations from recurring extreme heat events. Final mortality figures will be published through official government portals to support future health policies.
