Awareness of the UV Index is crucial in Santa Cruz de Tenerife, where the sun shines brightly throughout the year. Understanding UV levels is essential for protecting your skin from sunburn and long-term health risks, ensuring you enjoy the outdoors safely. With a Csb climate characterized by warm temperatures and rising UV exposure, especially around midday when levels peak at 12, residents and visitors must be vigilant. By monitoring the UV Index, you can take proactive measures to safeguard your skin while relishing the beautiful Tenerife sun.
As the sun rises, the UV Index dramatically climbs throughout the morning, starting at a mere 0 at 7:00 AM. By 8:00 AM, it nudges up to 1, but things really heat up at 10:00 AM when it reaches 3. The peak of the day arrives around 1:00 PM, when the index hits a sizzling 11, just before maxing out at 12 at 2:00 PM. Afterward, a steady decline ensues, with the index falling to 6 by 5:00 PM and dropping further to 2 by 7:00 PM. This data emphasizes the need for sun protection during those peak hours, particularly between 11:00 AM and 2:00 PM, when the sun is most intense!
