The Canary archipelago has registered 85 fatalities related to high temperatures over the past two months. Of these, 44 occurred in the province of Las Palmas and 41 in the province of Santa Cruz de Tenerife. The MoMo system, part of the Carlos III Health Institute, estimates that this heat-related mortality has risen by 67% compared to the same period in 2025, when 51 deaths were recorded.
The month of August has been particularly dangerous, with a total of 75 deaths attributed to heat in the Canary Islands. In July, another ten people died as a consequence of extreme temperatures. The monitoring panel indicates that there was one daily death due to heatstroke between July 8 and 19, except on the 15th and 16th.
High temperatures remained at tolerable levels until July 31, but since then, the MoMo system has recorded at least one death daily. August 9 was the most critical day, with an estimated nine fatalities in the archipelago due to heat. This August is shaping up to be one of the most dangerous in recent years, surpassing the 22 deaths recorded in August 2025 and the 23 in 2024.
The report details that over half of the 85 deaths are among individuals over 85 years old (44 cases). Another 19 victims were between 75 and 84 years old. Fatalities were also recorded in younger age groups, including five people aged 45 to 64 and two aged 15 to 44. An infant died from heatstroke in Fuerteventura on August 4.
The impact of heat has been more severe among Canarian women, with 51 deaths compared to 34 recorded among men in the archipelago. Heat exacerbates pre-existing conditions, being the main indirect cause of most deaths, especially in the elderly, although it can also cause direct and fatal heatstroke.
Across the rest of Spain, heatwaves have caused 3,151 heat-related deaths since last month, nearly a thousand more than in the same period of 2025.
