As residents of Xicheng, China, it’s essential to stay informed about the UV Index, a crucial indicator of sun exposure that can significantly impact your skin health. Understanding UV levels is vital for preventing sunburns and reducing the risk of long-term skin damage, especially given the region's Dwa climate which can lead to intense sunlight around midday. With peak UV Index values reaching up to 11 during the hottest hours, it’s important to take protective measures to enjoy the sunny days while safeguarding your skin from harmful rays. Familiarizing yourself with the UV Index will empower you to stay safe and make the most of outdoor activities.
The UV Index throughout the day showcases a clear pattern of rising and falling intensity. Starting at a mild 2 at 7:00 AM, the levels climb steadily, peaking at 11 by noon—the most intense period of sunlight. As the afternoon progresses, the index remains high, tapering off to 10 at 1:00 PM, before gradually descending. By 3:00 PM, it drops to 5, and the evening settles in with indices of 3 at 4:00 PM, and a gentle decline to 1 by 7:00 PM. This progression highlights the importance of sun protection during peak hours—particularly between 10 AM and 2 PM—when the UV exposure is at its highest.
