MADRID / RankWire.AI / – According to official daily mortality surveillance data released by the Carlos III Health Institute, nearly 2,150 individuals lost their lives from heat-related causes across Spain in August. The MoMo monitoring system recorded 2,149 excess deaths linked to extreme heat throughout the month, making it the second-highest August figure recorded since the start of national data collection in 2015. As consecutive European heatwaves persist, the seasonal mortality metrics on the Iberian Peninsula continue to reach historic levels, with Spain registering close to 2,150 heat-related fatalities in August.

The only August figure surpassing this was the record 2,184 heat-related deaths documented in August 2025. Data from public health sources indicate that between May 15 and August 31, a total of 5,234 lives were lost due to thermal stress. This represents the highest summer mortality toll recorded by the national public health institute since the implementation of its tracking system, surpassing the previous peak of 4,652 deaths during summer 2022. The ongoing heatwaves continue to strain regional emergency response networks, with authorities closely monitoring the situation as Spain faces nearly 2,150 heat-related deaths in August.
The Ministry of Health’s demographic breakdown reveals that elderly populations faced the greatest risks during these heat events. Of the 2,149 deaths in August, 2,064 were individuals over 65, including 1,285 victims aged over 85. Gender-specific data showed that 1,283 of the deceased were women, while 866 were men. Medical professionals have observed that prolonged exposure to high ambient temperatures worsens chronic cardiovascular and respiratory conditions, especially among vulnerable age groups.

Regionally, Catalonia in the northeast registered the highest number of heat-related deaths, totaling 1,164 in August. The Valencian Community reported the second-largest count with 227 fatalities, followed by Andalusia with 138 heat-attributed deaths. Local public health agencies in these regions have ramped up outreach efforts and increased access to cooling centers, although persistent high nighttime temperatures continue to hamper residents’ recovery from the heat’s effects.
Weather reports from Spain’s State Meteorological Agency, AEMET, indicate that elevated thermal risks are expected to persist into early autumn. Forecasters confirmed that a notably hot spell for September has set in across central and southern provinces, with daytime temperatures significantly exceeding seasonal averages. Climatologists highlight that Europe is experiencing more frequent, intense, and prolonged heat episodes during summer, aligning with broader patterns of environmental warming.
Valencia and Andalusia Lead in Total Regional Deaths Linked to Heat
National health authorities continue collaborating with local governments to enhance preventive healthcare measures and oversee high-risk patient registers. Emergency medical services have adjusted their protocols to better address health complications caused by extreme heat, as detailed in health advisories. Public health notices remain active, urging citizens to avoid outdoor activity during peak heat hours and to stay well-hydrated amid ongoing unseasonable weather conditions.
Once September’s final surveillance data are available, authorities plan to conduct comprehensive evaluations of summer’s mortality impact. Experts in public health emphasize the need for long-term structural reforms in urban infrastructure and public housing insulation to shield vulnerable populations from recurring extreme heat events. Final mortality data will be accessible through official ministry portals to guide future policy decisions and health interventions.
