Understanding the UV Index in Tulongshan, China is crucial for safeguarding your skin and overall health. With varying levels of ultraviolet radiation throughout the day, awareness of UV levels can help prevent sunburn and reduce the risk of long-term skin damage. The climate in Tulongshan, characterized by its Dwa zone, exposes residents and visitors to significant UV radiation, particularly during peak hours like 10:00 AM to 1:00 PM when the index reaches its highest at 9. Stay informed to enjoy the outdoors safely while protecting your skin from harmful rays.
The UV Index climbs steadily throughout the morning, starting at a manageable 3 at 07:00 and surging to a peak of 9 between 10:00 and 12:00. During these hours, sun protection is crucial as the intensity remains high, ideal for outdoor activities if precautions are taken. As the afternoon sets in, the index begins to decline, dropping to 8 by 13:00, and then tapering off to 6 at 14:00. By the afternoon, the risks lessen significantly, with readings falling to 4 at 15:00, and a gentle decline continues into the evening, reaching 1 by 17:00 and finally settling at 0 after 19:00. This pattern emphasizes the importance of maximizing sun safety during the midday hours, where the sun's rays are at their strongest.
