Understanding the UV Index is crucial for residents of Huetor Santillan, Spain, where sunny Mediterranean days can lead to significant ultraviolet exposure. Being aware of UV levels is essential not only for preventing painful sunburns but also for maintaining healthy skin in the long run. With Huetor Santillan’s Csa climate, which features hot summers and plenty of sunshine, vigilance against high UV Index readings—especially during peak hours—is vital. On sunny days, the UV Index can soar as high as 12, underscoring the importance of sun safety measures to protect your skin from potential damage.
As the sun rises, the UV Index slowly increases, starting at a gentle 1 at 7:00 AM and 8:00 AM. By 9:00 AM, it climbs to 2, but it’s not until 10:00 AM that we see a more noticeable surge to 4.

Just after, it stays strong at 11 until 3:00 PM before beginning to taper off. As the day winds down, the UV Index decreases to 4 by 6:00 PM before settling at 2 by 7:00 PM. Remember to protect your skin during those peak hours, particularly from 11:00 AM to 3:00 PM, when the sun's rays are most potent!
