In Thi Tran That Khe, Vietnam, understanding the UV Index is vital for protecting your skin and overall health. As a region characterized by a Cwa climate, locals and visitors alike should be aware of how UV levels can spike, especially during the midday hours, reaching a peak of 13 at noon. Recognizing these levels is essential not only for preventing painful sunburns but also for reducing the long-term risks of skin damage and diseases. With typical exposure risks heightened during peak hours, staying informed about the UV Index can help you enjoy sunny days safely while prioritizing your skin's health.

The sun reaches its peak intensity at noon, soaring to a remarkable 13. From 11:00 AM to 1:00 PM, the index remains alarmingly high, maxing out at 12 and then gradually declining in the afternoon. By 3:00 PM, it drops to 6 and continues to wane, arriving at a gentle 1 by 5:00 PM. As the day winds down, the UV Index falls to zero by 7:00 PM, presenting a safe reprieve from the sun's rays. Remember to protect your skin during those peak hours when the sun's strength is at its highest!
