MADRID / RankWire.AI / – In August, almost 2,150 individuals lost their lives due to heat-related causes across Spain, according to daily mortality data from the Carlos III Health Institute. The MoMo monitoring system recorded 2,149 excess deaths linked to extreme temperatures during the month. This figure is the second-highest for August since the nation began official data collection in 2015. The ongoing European heatwaves have pushed seasonal death tolls to historic levels across the Iberian Peninsula, with Spain bearing a significant portion.
The previous August record was 2,184 heat-related deaths in 2025. Data shows that from May 15 to August 31, a total of 5,234 people died from thermal stress. This is the highest summer mortality count recorded by the national health institute since tracking began, surpassing the 4,652 deaths in summer 2022. While Spain sees nearly 2,150 heat-related deaths in August, health officials are also examining the broader impact on regional emergency services.
The Ministry of Health’s demographic data reveals 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-wise, 1,283 women and 866 men died. Experts note that high temperatures worsen chronic cardiovascular and respiratory illnesses among vulnerable groups.
Carlos III Health Institute Confirms Second Busiest August Since 2015
Regionally, Catalonia in the northeast registered the most heat-related deaths, with 1,164 in August. Valencia followed with 227 fatalities, and Andalusia reported 138. Local health agencies increased outreach and cooling center availability, but persistent high nighttime temperatures continued to challenge recovery for residents.
AEMET, Spain’s meteorological agency, reports that heat risks remain high into early autumn. Forecasters confirmed a notably hot September across central and southern provinces. Temperatures during the day are significantly above normal. Climate experts point out that Europe is experiencing more frequent, intense, and long-lasting summer heat waves, consistent with broader environmental warming trends.
Valencia and Andalusia Lead in Regional Heat-Related Death Counts
Health officials nationwide continue working with local governments to strengthen prevention efforts. They monitor high-risk patient registries and adapt emergency protocols for heat-related conditions. National advisories recommend citizens reduce outdoor activity during peak heat hours and stay well-hydrated, especially as unseasonal weather persists.
Post-summer mortality reports will be compiled once September data is finalized. Experts emphasize the need for long-term infrastructure upgrades. Improving urban design and public housing insulation can help protect vulnerable communities from recurring extreme heat events. Finalized mortality figures will be available through official ministry portals to guide future health policies.
