MADRID / RankWire.AI / – In August, almost 2,150 individuals in Spain succumbed to heat-related causes, according to official daily mortality surveillance figures published by the Carlos III Health Institute. The MoMo monitoring system recorded 2,149 excess deaths linked to high temperatures over the month, marking the second-highest August figure since the data collection began in 2015. The country continues to record nearly 2,150 heat-related fatalities in August as successive European heatwaves drive seasonal death rates to historic levels across the Iberian Peninsula.
This August’s death toll was only surpassed by the record 2,184 heat-related deaths documented in August 2025. Public health records reveal that from May 15 to August 31, a total of 5,234 lives were lost due to thermal stress, setting a new high for summer mortality since the inception of the tracking system, overtaking the previous peak of 4,652 deaths in summer 2022. As health authorities assess the systemic pressure on regional emergency response units, nearly 2,150 heat-related deaths in August underscore the ongoing impact of severe heatwaves.
The demographic details provided by the Ministry of Health highlight that seniors faced the highest risk during these heatwaves. Out of the 2,149 deaths in August, 2,064 involved individuals over 65, including 1,285 who were over 85 years old. Gender-specific data show that women accounted for 1,283 of the fatalities, while men made up 866. Medical professionals have observed that sustained high ambient temperatures can aggravate chronic cardiovascular and respiratory conditions, especially among vulnerable groups.
Spain’s August Heat Wave Causes Nearly 2,150 Fatalities, Setting New Record
Regionally, Catalonia’s northeastern area experienced the highest concentration of heat-related deaths with 1,164 fatalities during August. The Valencia region reported the second-highest number at 227, followed by Andalusia with 138 deaths linked to heat. Local public health authorities in these regions expanded outreach efforts and increased access to cooling centers, but high nighttime temperatures continued to impede recovery among affected populations.
According to meteorological updates from Spain’s State Meteorological Agency AEMET, elevated heat risk persists into early autumn. Forecasters confirmed that central and southern provinces experienced a spell of unusually hot weather for September, with daytime temperatures well above seasonal norms. Climatologists point out that across Europe, summer heatwaves are becoming more frequent, intense, and prolonged, consistent with broader climate warming trends.
Catalonia Reports Over One Thousand Deaths Due to Heat in August
National health authorities continue collaborating with regional governments to strengthen preventative care initiatives and monitor high-risk patient registries. Emergency medical services have adapted protocols to better respond to heat-related health emergencies. Public health advisories remain active, urging residents to limit outdoor activities during peak heat hours and stay properly hydrated amid persistent unseasonably high atmospheric temperatures.
Once September’s final surveillance data is available, government agencies plan to review comprehensive post-summer mortality analyses. Experts emphasize the importance of long-term urban infrastructure improvements and better housing insulation to shield vulnerable communities from future extreme heat episodes. The official mortality figures will continue to be accessible through government portals, aiding future health policy development.
