Heat Health Risk Warnings Extended Across Canary Islands

Public Health Alert

The General Directorate of Public Health at the Canary Islands Health Service (SCS) has updated its health risk alerts following predictions from the State Meteorology Agency (AEMET). From 17 September, alerts will also apply to Lanzarote and El Hierro, while existing warnings are being expanded in Tenerife, Gran Canaria, and La Palma. The alert level has been raised to red for the metropolitan area of Tenerife, with orange alerts activated in the west of La Palma and El Hierro, and yellow alerts in Lanzarote and northern Tenerife. Furthermore, a yellow alert remains in effect for Gran Canaria and the eastern region of La Palma. Maximum temperatures are projected to reach 38ºC, with 18 September identified as the day of greatest risk.

Most Affected Areas

The municipalities most impacted include San Bartolomé (Lanzarote), San Bartolomé de Tirajana and Santa Lucía de Tirajana (Gran Canaria), Frontera (El Hierro), Santa Cruz (Tenerife), and Tazacorte (La Palma). This rise in temperatures increases the risk of heat-related illnesses, particularly for sensitive and vulnerable groups such as infants, individuals over 65, pregnant women, and those with chronic health conditions. The alert will remain active at least until Saturday, 20 September.

Advice for Residents

The General Directorate of Public Health advises the public to stay well-hydrated, consume light meals, avoid direct sunlight during peak hours, limit intense physical activity, and seek out cool indoor spaces. Particular attention should be given to vulnerable individuals and those who are highly exposed to heat. In the event of symptoms such as dizziness, weakness, cramps, fever, or loss of consciousness related to heat, immediate medical attention should be sought. In emergencies, citizens are urged to call 112.
