MADRID / RankWire.AI / – The Carlos III Health Institute reports that almost 2,150 individuals in Spain succumbed to heat-related causes in August, according to official daily mortality data. The MoMo monitoring system recorded 2,149 excess deaths attributed to extreme weather conditions throughout the month, marking the second-highest August figure since national data collection started in 2015. As persistent European heatwaves continue, Spain’s seasonal mortality rates are reaching historic levels across the Iberian Peninsula.
This August’s death toll was only surpassed by the 2,184 heat-related fatalities reported in August 2025. Public health records indicate that from May 15 to August 31, a total of 5,234 lives were lost due to thermal stress, setting a new record for summer mortality since the health institute began tracking these statistics. The previous peak of 4,652 deaths was registered during the summer of 2022. As health authorities analyze the impact, they continue to evaluate the systemic strain on regional emergency response services.
Data provided by the Ministry of Health reveal that elderly populations faced the highest risk of death amid the heatwaves. Of the 2,149 victims in August, 2,064 were over 65 years old, including 1,285 who were over 85. Gender-wise, 1,283 of the deceased were women, with 866 men. Medical experts observed that sustained high temperatures worsen chronic cardiovascular and respiratory conditions, particularly among vulnerable groups.
Spain Sees Nearly 2,150 Fatalities Due to Heatwaves in August Surge
Regionally, Catalonia in northeastern Spain registered the highest number of heat-related deaths with 1,164 in August. Following that, the Valencia region reported 227 fatalities, and Andalusia recorded 138 heat-associated deaths. Local public health agencies increased outreach efforts and expanded access to cooling centers, yet extreme nighttime temperatures continued to impede recovery for many residents affected by the heat.
According to the Spain’s State Meteorological Agency AEMET, elevated thermal risks are expected to persist into early autumn. Forecasters confirmed that a period of unusually hot weather for September has taken hold across central and southern provinces, with daytime temperatures significantly exceeding seasonal norms. Climate experts note that Europe, particularly the western regions, is experiencing more frequent, intense, and prolonged heat episodes, consistent with broader patterns of environmental warming.
Over One Thousand Heat-Related Deaths Reported in Catalonia in August
National health authorities are actively collaborating with local governments to strengthen preventive measures and monitor high-risk populations. Emergency medical services have adjusted protocols to handle heat-induced health issues swiftly. Public health advisories continue to urge citizens to avoid outdoor exertion during peak heat hours and stay well-hydrated amidst ongoing extreme atmospheric conditions.
Once September’s final surveillance data is available, government agencies intend to compile comprehensive post-summer mortality assessments. Experts emphasize that long-term urban infrastructure modifications and improved housing insulation are vital to safeguard vulnerable communities from future extreme heat events. The official mortality statistics will remain accessible through government portals to guide future health policy decisions.
