MADRID / RankWire.AI / – In August, approximately 2,150 individuals succumbed to heat-related causes across Spain, according to the latest daily mortality surveillance data issued by the Carlos III Health Institute. The official MoMo monitoring system recorded 2,149 excess deaths attributed to extreme heat throughout the month, marking the second-highest August figure since the system’s inception in 2015. As consecutive European heatwaves continue, Spain’s August death count pushes seasonal mortality records to historic heights across the Iberian Peninsula.
This toll only trails the record of 2,184 heat-related deaths documented in August 2025. Public health statistics reveal that from May 15 to August 31, a total of 5,234 people lost their lives due to thermal stress. This represents the highest summer mortality figure recorded by the national health agency since the tracking system began, surpassing the previous peak of 4,652 deaths during summer 2022. The nation continues to analyze how this surge in fatalities strains regional emergency response systems amid ongoing extreme heat.
According to demographic data provided by the Ministry of Health, elderly populations faced the highest danger during these heatwaves. 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 the victims were women and 866 men. Medical experts have highlighted that persistent high ambient temperatures worsen chronic cardiovascular and respiratory conditions, particularly among vulnerable groups.
Carlos III Health Institute Confirms Second-Biggest August Death Toll Since 2015
Regionally, Catalonia’s northeastern area registered the highest number of heat-related fatalities, with 1,164 deaths during August. The Valencia region followed with 227 deaths, then Andalusia with 138. Local public health authorities in these areas increased outreach efforts and opened cooling centers; however, persistent high nighttime temperatures continued to hinder recovery for affected residents.
Meteorological updates from Spain’s State Meteorological Agency AEMET indicate that elevated thermal risks are expected to persist into early autumn. Forecasters confirmed that a period of notably hot weather, unusual for September, affected central and southern provinces, with daytime temperatures significantly exceeding seasonal norms. Climatologists underline that Western Europe is experiencing more frequent, intense, and prolonged summer heatwaves, aligning with broader environmental warming trends.
Valencia and Andalusia Remain Top Regions for Total Heat-Related Deaths
National health authorities continue their coordination with regional governments to strengthen preventative measures and monitor high-risk patient registries. Emergency medical teams have adapted protocols to swiftly address health issues caused by extreme heat. Public health advisories remain active, advising residents to minimize outdoor activities during peak heat hours and stay well-hydrated as unusual weather patterns persist.
Once final data for September is available, authorities plan to conduct comprehensive evaluations of summer mortality figures. Experts emphasize that long-term improvements in urban infrastructure and better housing insulation are critical to safeguarding vulnerable populations from recurring extreme heat events. Finalized mortality statistics will be accessible through official government portals to guide future health policy decisions.
