In Yi Xian, China, being aware of the UV Index is essential for protecting your skin and overall health. Understanding UV levels is crucial to prevent sunburn and reduce the risk of long-term skin damage, especially given the region's Dwa climate, characterized by distinct seasons and potentially high sun exposure. With UV indices rising sharply to a peak of 10 around midday, it’s vital for residents and visitors alike to stay informed and take appropriate precautions to enjoy the beautiful outdoors without compromising their skin health.
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!

As the seasons change, so does the UV Index and the associated risk of sunburn. In January and December, the UV Index is low (2), allowing for 45 minutes of safe sun exposure without significant risk. By February, the Index rises to moderate (4), reducing safe exposure time to 30 minutes. The most high-risk months occur from March through September, where the UV Index peaks at 10 in July and remains very high (9 or 8) throughout the summer months. During this period, safe exposure time significantly decreases to only 15 minutes. As autumn approaches, the risk begins to lower, with the Index falling to 6 in October and then back to moderate (3) in November. Visitors and residents are advised to take appropriate precautions starting in March, including using sunscreen, wearing protective clothing, and seeking shade during peak hours, particularly between 11 a.m. and 4 p.m.
