Understanding the UV Index is crucial for residents of Yongheng, China, as it serves as a vital tool for sun safety and skin health. With its Dwa climate, Yongheng experiences significant UV exposure, particularly during peak hours when levels can soar to 9. Awareness of the UV Index helps in gauging the risk of sunburn, making it essential for planning outdoor activities and protecting your skin. On sunny days, even a short amount of time under the midday sun can lead to harmful effects, so knowing the UV levels is key to enjoying the beautiful weather while staying safe.
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.
