Understanding the UV Index in Cati, Spain is crucial for protecting your skin from harmful ultraviolet radiation. With the region's Mediterranean climate characterized by long, hot summers, awareness of UV levels can help prevent sunburn and maintain skin health. Remember, during peak hours, particularly around noon when the UV Index can soar to 11, the risk of skin damage significantly increases. Staying informed about the UV Index allows residents and visitors alike to enjoy the sunshine safely and responsibly, ensuring outdoor activities remain enjoyable year-round while minimizing health risks.
As the sun rises, the UV Index slowly awakens, beginning at a mild 1 at 07:00 and barely climbing to 2 by 09:00. However, as the day progresses, the intensity ramps up dramatically, peaking at a striking 11 between 13:00 and 14:00—a reminder of the sun's power. From 10 at 15:00 to 4 by 18:00, we see a gradual decline, highlighting the need for sun protection during midday hours when the index is at its highest. As light fades into the evening, the UV Index drops back to a gentler 2 by 19:00, offering a moment of respite. Enjoy those early hours, but remember to stay shaded when the sun is at its zenith!
