Extreme heat warnings will come into effect on Sunday, 13 September, according to the General Directorate of Public Health of the Canary Health Service (SCS). The alert follows forecasts from the State Meteorological Agency (AEMET) predicting extreme temperatures that could pose health risks.
A Level 2, orange alert, indicating a moderate risk, has been issued for vulnerable groups such as those over 65 or adults with health issues exacerbated by heat, particularly in Las Palmas de Gran Canaria and Telde in Gran Canaria, Santa Cruz de Tenerife-El Rosario in Tenerife, and the entire island of Lanzarote.
A Level 1, yellow alert, indicating a mild risk, applies to vulnerable groups in Fuerteventura.
The warnings will begin on Sunday, and the duration is currently uncertain; updates will be provided as more information becomes available. An increase in maximum temperature thresholds signals an elevated risk of heat-related illnesses, particularly for sensitive populations.
Health authorities recommend considering rescheduling outdoor activities that require physical exertion and staying in cool places as much as possible. They also advise extra precautions during cultural or religious events to monitor for symptoms related to heat exposure.
On Monday, the islands are expected to experience a dust cloud event, which could worsen heat symptoms and reduce humidity, impacting how temperatures are perceived.
Those particularly vulnerable to heat include infants, pregnant women, seniors, individuals with pre-existing respiratory, cardiovascular, or renal conditions, and others on medications such as diuretics or benzodiazepines. Symptoms to watch for include intense thirst, weakness, dizziness, nausea, headaches, and potential heat stroke signals like fainting or seizures.
To prevent dehydration, the public is advised to drink water regularly, avoid caffeine and alcohol, eat light meals including salads and fruits, and care for vulnerable individuals such as children and the elderly.
While outdoors, avoid sun exposure during peak hours, wear loose clothing, and plan vigorous activity for early morning or late afternoon. Inside, keep spaces cool, avoid heat-producing appliances, and prioritise time in air-conditioned areas.
During this heatwave, limiting outdoor time and refraining from intense physical activity is strongly recommended. Seek medical attention if severe symptoms arise, and call 112 for emergencies.
