Understanding the UV Index is crucial for residents of Shitouhe, China, especially when it comes to protecting your skin from harmful ultraviolet radiation. With UV levels peaking at 9 between 10:00 AM and 1:00 PM, awareness can help prevent sunburns and reduce long-term skin health risks. The region's Dwb climate indicates distinct seasons, but during warmer months, the risk of high UV exposure increases.

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.
