51 people have died from heat-related deaths so far this summer in the Canary Islands
The Canary Islands have recorded 51 heat-related deaths so far this summer, more than double the figure for the same period last year, according to Spain’s Daily Mortality Monitoring System (MoMo), run by the Carlos III Health Institute.
Between 15th May and 18th August 2025, there were 51 deaths across the islands attributed to extreme heat, compared to 26 during the same period in 2024. Almost all of the victims were elderly or vulnerable, with 44 of the deceased aged over 65.
July and August Heatwaves Prove Deadly
The most lethal spell came during the intense heatwave between 17th and 26th July, when 36 people lost their lives. The most recent episode, from 10th to 18th August, claimed a further 15 victims.
August has been marked by searing heat, with several days above 40°C in Gran Canaria, compounded by calima (dust haze from the Sahara) and hot winds, which increased the health risks, especially among the elderly.
Of the 15 deaths this month, 14 were over the age of 65, seven of them over 85, and only one was under 65. In July, 30 of the 36 victims were over 65. Women have been disproportionately affected, with 30 female fatalities compared to 21 male deaths across the summer.
National Figures Also Rising Sharply
The Canaries reflect a wider trend across Spain, where an estimated 2,635 people have died from heat so far this summer, up 40% on last year’s figure of 1,856.
Most victims nationwide were elderly: 2,529 were over 65, and of these, 1,747 were aged 85 or older. The deadliest period was the recent early-August heatwave, when more than 100 people per day died from heat-related causes, peaking on Sunday 17 August with 125 deaths.
Heat Risks and Health Warnings
Experts stress that extreme heat can kill both directly, through heatstroke, and indirectly, by worsening pre-existing health conditions, particularly in older people and those with chronic illnesses. At least 23 deaths in Spain this summer have been confirmed as directly due to heatstroke, compared with 17 last year.
Authorities continue to warn residents and tourists to take precautions during hot spells: stay hydrated, avoid exertion in peak hours, look out for vulnerable relatives or neighbours, and follow official health advisories.
