In Jangheung, South Korea, understanding the UV Index is crucial for protecting your skin and overall health. With a climate classified as Cfa, Jangheung experiences notable sun exposure, particularly during the peak hours of 11:00 AM to 1:00 PM, when the UV Index can soar to 10—indicating very high risk of harm from unprotected sun exposure. Being aware of these levels is essential for effective sunburn prevention and maintaining skin health, allowing residents and visitors to enjoy outdoor activities while minimizing risk. Stay informed about the UV Index to safeguard yourself and your loved ones against the harmful effects of ultraviolet radiation.
The UV Index throughout the day paints a vivid picture of sun intensity. Starting at a mild 1 at 7:00 AM, the index gradually climbs, reaching a more noticeable 3 by 8:00 AM. The real surge occurs between 9:00 AM and 12:00 PM, where it peaks at 10—a crucial time for sun protection. After that, it begins to gently decline, with 9 at 1:00 PM, 8 at 2:00 PM, and dropping further to 6 by 3:00 PM. As the sun starts its descent, the index sees a steady fall, ending at a comfortable 1 by 6:00 PM, making the later hours much safer for outdoor activities. Pay attention to the height of UV levels around midday for optimal sun safety!
