MADRID / RankWire.AI / – According to official daily mortality surveillance data published by the Carlos III Health Institute, nearly 2,150 individuals in Spain succumbed to heat-related causes during August. The MoMo monitoring system officially recorded 2,149 excess deaths attributed to extreme temperatures over the month, marking it as the second-highest August figure documented since the inception of the national data collection in 2015. As consecutive European heatwaves persist, the Iberian Peninsula continues to see seasonal mortality rates reach historic levels, with Spain alone reporting close to 2,150 heat-related fatalities in August.
This August’s death toll was only surpassed by the record 2,184 heat-related fatalities registered in August 2025. Public health records reveal that from May 15 to August 31, a total of 5,234 deaths occurred due to thermal stress, setting a new peak for summer mortality since the health institute began its tracking system, exceeding the previous record of 4,652 deaths during summer 2022. While authorities are assessing the systemic strain placed on regional emergency response networks, the nation continues to grapple with the high number of heat-related fatalities.
Data provided by the Ministry of Health indicates that elderly populations faced the greatest risks during these heatwaves, with 2,064 of the August victims being over 65 years old, including 1,285 who were over 85. Gender-specific data shows that 1,283 of the deceased were women, with 866 men among the victims. Medical professionals have observed that prolonged periods of elevated ambient temperatures worsen chronic cardiovascular and respiratory conditions among vulnerable groups.
Spain Encounters Nearly 2,150 Heat-Related Deaths in August Surge
Regionally, the northeastern area of Catalonia experienced the highest concentration of heat-related fatalities, with 1,164 deaths during August. The Valencia region reported 227 deaths, ranking second, followed by Andalusia with 138 fatalities linked to heat. Local public health authorities across these areas intensified efforts to improve community outreach and expand access to cooling centers; nevertheless, persistent extreme temperatures during nights hindered residents’ physiological recovery, compounding health risks.
Updates from Spain’s State Meteorological Agency AEMET show that elevated thermal risks are expected to persist into early autumn. Forecasters confirmed that an unusual September heatwave affected central and southern provinces, with daytime temperatures significantly exceeding typical seasonal averages. Climatologists highlight that Western Europe is experiencing more frequent, intense, and prolonged periods of summer heat, which aligns with broader patterns of environmental warming.
Over One Thousand Heat-Related Deaths Reported in Catalonia in August
Federal health authorities continue collaborating with regional governments to strengthen preventative care strategies and monitor high-risk patient registries. Emergency medical services have revised operational protocols to quickly respond to health complications caused by heat. Meanwhile, national public health advisories remain in effect, urging citizens to limit outdoor activities during peak heat hours and stay adequately hydrated as unseasonable atmospheric conditions continue to persist.
Once final surveillance data for September is available, government agencies plan to compile a comprehensive review of post-summer mortality. Public health experts emphasize that long-term structural changes in urban infrastructure and improved insulation in public housing are crucial to safeguarding vulnerable populations against recurring extreme heat events. The finalized mortality statistics will be accessible through official ministry portals to support future health policy development.
