Canary Islands Issue Extreme UV Radiation Alert
The Canary Islands’ health authorities have issued an urgent warning for extreme UV radiation levels across the archipelago, advising residents and visitors to avoid direct sun exposure through July 6.
The Canary Islands’ General Directorate of Public Health has issued an urgent warning due to extreme climate conditions across the archipelago. The alert, which remains in effect until July 6, highlights dangerous levels of ultraviolet (UV) radiation. In the Tenerife municipalities of Santiago del Teide and Vilaflor de Chasna, radiation has reached an extreme risk threshold, prompting authorities to advise against any direct sun exposure.
According to the State Meteorological Agency (Aemet), the Canary Islands consistently record the highest radiation levels in Spain. This is largely due to the region’s high altitude, which intensifies sunlight. Currently, 29 municipalities are under maximum alert, while the rest of the islands face a "very high" risk.
Health officials warn that people should not be misled by the weather. Even on cooler, cloudy, or breezy days, UV rays remain just as powerful. A false sense of security can be dangerous, so it is essential to maintain sun protection—such as SPF 50+ sunscreen, protective clothing, hats, and sunglasses—regardless of the temperature.
These precautions are vital for long-term health. Scientific evidence shows that skin damage is cumulative, and sun exposure during childhood can lead to serious health issues later in life. Authorities are urging extra vigilance for vulnerable groups, including children, the elderly, those with pre-existing health conditions, and outdoor workers.
This warning applies to all daily activities, not just time spent at the beach. Because current UV levels can cause skin and eye damage in a very short time, residents and visitors in high-risk areas like Santiago del Teide and Vilaflor de Chasna are urged to avoid direct sunlight throughout the day.
