In Jiejiazhuang, China, being aware of the UV Index is crucial for safeguarding your skin health and preventing sunburn. With a climate characterized by warm summers and cold winters, residents often experience significant UV exposure, particularly during peak hours when the UV Index can climb to 11—a level that indicates a very high risk of harm from unprotected sun exposure. Understanding these UV levels empowers you to take necessary precautions, ensuring your outdoor activities remain enjoyable and safe. Whether you’re lounging outside, enjoying the area's beautiful parks, or participating in local events, being informed about the UV Index can make all the difference in protecting your skin from the sun's harmful rays.
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.
