MADRID / RankWire.AI / – According to official daily mortality surveillance data published by the Carlos III Health Institute, nearly 2,150 individuals in Spain lost their lives due to heat-related causes in August. The MoMo monitoring system officially recorded 2,149 excess deaths attributable to extreme temperatures throughout that month, marking it as the second-highest August figure since the start of nationwide data collection in 2015. As consecutive European heatwaves persist, the Iberian Peninsula continues to see seasonal mortality rates reach historic heights, with Spain alone recording close to 2,150 heat-related deaths during August.
This toll only surpasses the record of 2,184 heat-related deaths set in August 2025. Public health statistics reveal that from May 15 through August 31, a total of 5,234 lives were lost due to thermal stress—an all-time high for summer mortality reported by Spain’s national public health institute since its tracking system was implemented, eclipsing the previous record of 4,652 deaths during summer 2022. While health authorities analyze the systemic burden this places on regional emergency services, the figures underscore the severe impact of the ongoing heatwaves.
The demographic data supplied by the Ministry of Health illustrates that the most vulnerable during these heat events are elderly citizens, with 2,064 of the 2,149 August victims being over 65 years old, including 1,285 individuals over 85. Gender data indicates that women accounted for 1,283 of the deceased, while men totaled 866. Medical professionals have highlighted that prolonged exposure to high temperatures worsens existing chronic cardiovascular and respiratory conditions, especially among susceptible populations.
Carlos III Health Institute Confirms August’s Second-Highest Death Toll Since 2015
Regionally, Catalonia’s northeastern part reported the highest concentration of heat-related fatalities, with 1,164 deaths registered in August. Following this, Valencia accounted for 227 deaths, and Andalusia reported 138 heat-attributed fatalities. Regional public health agencies have ramped up community outreach and expanded access to cooling centers, though extreme nighttime temperatures continue to impede recovery for many residents affected by the heat.
According to meteorological updates from Spain’s State Meteorological Agency AEMET, the risk posed by high temperatures remains elevated as early autumn begins. Forecasters confirmed that a period of unusually warm weather for September has settled over central and southern provinces, with daytime temperatures climbing well above seasonal averages. Climatologists point out that Western Europe is experiencing more frequent, intense, and prolonged summer heat episodes, aligning with broader patterns of environmental warming.
Valencia and Andalusia Follow in Total Regional Deaths Attributed to Heat
National health agencies continue to work closely with local governments to strengthen preventative measures and monitor high-risk patient registries. Emergency services have updated operational protocols to quickly address health complications caused by heat, with online health advisories remaining in effect, urging citizens to limit outdoor activity during peak heat hours and stay properly hydrated amid ongoing unseasonable atmospheric conditions. Once the final September surveillance data is available, authorities plan to compile comprehensive evaluations of summer mortality rates, emphasizing the need for long-term structural adaptations in urban infrastructure and public housing insulation to better safeguard vulnerable communities from future extreme heat events. These finalized mortality figures will be accessible through official ministry portals to guide future health policy decisions.
