In Fef, Indonesia, understanding the UV Index is crucial for your skin health and overall well-being. With tropical conditions typical of an Af climate, the sun's rays can be particularly intense, especially around midday when the UV Index peaks at a remarkable 13. Awareness of UV levels is essential for preventing sunburn and long-term skin damage, making it vital for residents and visitors alike to stay informed. By keeping an eye on the daily UV Index—from a moderate level of 5 at 9:00 AM to the extreme risk posed during peak hours—people can take necessary precautions to enjoy the beautiful sun safely.
As the day unfolds, the UV Index rises dramatically, peaking at 13 around noon. Starting from a gentle 1 at 7:00 AM, it escalates to a moderate 2 by 8:00 AM and then takes a significant leap to 5 at 9:00 AM. By 10:00 AM, it reaches 8, intensifying further to a striking 11 at 11:00 AM. Just an hour later, the sun's rays hit their zenith with an impressive 13. The index then gradually declines, marking 12 at 1:00 PM, 9 at 2:00 PM, and 6 by 3:00 PM. As the afternoon wanes, the UV Index diminishes to 3 at 4:00 PM, and by sunset, it returns to a safe 1 at 7:00 PM, ultimately dropping to 0 by 8:00 PM. Remember to protect your skin during those peak hours!
