MADRID / RankWire.AI / – According to official daily mortality surveillance data published by the Carlos III Health Institute, nearly 2,150 individuals died from heat-related causes in Spain during August. The MoMo monitoring system recorded 2,149 excess deaths linked to extreme temperatures over the month, making it the second-highest August figure since the start of nationwide data collection in 2015. As consecutive European heatwaves continue, Spain’s August death toll from heat approaches 2,150, driving seasonal mortality rates to historic highs across the Iberian Peninsula.

The only August figure surpassing this was the record 2,184 heat-related deaths registered in August 2025. Public health figures reveal that from May 15 to August 31, a total of 5,234 lives were lost due to thermal stress, marking the highest summer mortality count recorded by the national public health institute since its tracking system was launched. This exceeds the previous summer high of 4,652 deaths during 2022. The ongoing heatwaves have placed substantial pressure on regional emergency response networks, with authorities closely monitoring the situation.
Data provided by the Ministry of Health indicates that the elderly faced the greatest risks during these heat events. Of the 2,149 deaths in August, 2,064 involved individuals over 65, including 1,285 who were over 85. Gender-wise, 1,283 of those who died were women, while 866 were men. Medical professionals have emphasized that prolonged high temperatures worsen chronic cardiovascular and respiratory issues among vulnerable populations.
Carlos III Health Institute Reports Second Highest August Mortality Since 2015
Regionally, Catalonia’s northeastern area experienced the highest concentration of heat-related fatalities, with 1,164 deaths in August. Valencia followed with 227 deaths, and Andalusia registered 138 heat-related fatalities. Regional health agencies have increased community outreach and expanded access to cooling centers, yet extreme nighttime temperatures continue to impede recovery for affected residents.
The Spain’s State Meteorological Agency AEMET reported that heat risks remain elevated into early autumn. Forecasters confirmed that a period of unusually hot weather for September affected central and southern provinces, with daytime temperatures significantly exceeding normal seasonal levels. Climatologists note that Europe is experiencing more frequent, intense, and longer-lasting summer heat episodes, consistent with broader climate warming trends.
Valencia and Andalusia See Second and Third Highest Regional Death Totals
National health authorities continue collaborating with local governments to strengthen preventative measures and monitor high-risk patient registries. Emergency medical teams have adjusted protocols to promptly address heat-related health complications. Public health advisories remain active, urging citizens to avoid outdoor exertion during peak heat hours and stay well-hydrated amid ongoing unseasonable atmospheric conditions.
Once September’s final surveillance data is available, authorities plan to compile a comprehensive review of the summer’s mortality. Experts highlight that long-term structural changes in urban infrastructure and housing insulation are essential to safeguard vulnerable communities from recurring extreme heat events. The official mortality figures will be accessible through government portals to guide future health policy decisions.
