MADRID / RankWire.AI / – Official daily mortality data published by the Carlos III Health Institute shows that almost 2,150 people in Spain lost their lives due to heat in August. The MoMo monitoring system recorded 2,149 excess deaths linked to extreme temperatures during the month. This is the second-highest August figure since official data collection began in 2015. As consecutive European heatwaves persist, seasonal mortality rates across the Iberian Peninsula continue reaching historic heights.
The highest August death toll was 2,184 in 2025. Data from public health officials shows that from May 15 to August 31, a total of 5,234 people died from thermal stress. This summer’s toll is the highest recorded by the national public health institute since the tracking system started, surpassing the previous peak of 4,652 deaths in summer 2022. While Spain reports nearly 2,150 heat-related fatalities in August, health authorities are assessing the strain on regional emergency services.
The Ministry of Health’s demographic data reveal that the elderly faced the highest risk during the heatwaves. Of the 2,149 deaths in August, 2,064 were people over 65, including 1,285 over 85. Gender data shows 1,283 women and 866 men among the deceased. Experts note that prolonged high temperatures worsen chronic heart and lung conditions, especially in vulnerable groups.
Spain Sees Nearly 2,150 Deaths from Heat in August Spike
The northeastern region of Catalonia experienced the highest number of heat-related deaths, with 1,164 in August. Valencia reported the second-highest count at 227 fatalities, followed by Andalusia with 138. Local health agencies expanded outreach programs and cooling centers. Nonetheless, extreme nighttime heat made recovery difficult for affected residents.
The State Meteorological Agency AEMET reports that high temperatures remain into early autumn. Forecasters say September’s unusually hot weather has affected central and southern provinces. Temperatures during the day are significantly above normal for the season. Climatologists point out that Europe is experiencing more frequent, intense, and longer heatwaves, reflecting broader climate warming trends.
Catalonia Reports Over One Thousand Deaths Due to Heat in August
Health authorities continue working with local governments to boost preventative care and monitor high-risk patients. Emergency services have adjusted their protocols to handle heat-related health issues quickly. Public health advisories urge citizens to limit outdoor activities during peak heat hours and stay well-hydrated amid ongoing abnormal weather conditions.
Once September’s final data are available, officials plan to review the total summer mortality. Experts emphasize that long-term urban infrastructure improvements and better housing insulation are crucial to protecting vulnerable populations. The official mortality figures will be accessible through government portals, helping shape future health policies.
