In Jiuguan, China, staying informed about the UV Index is crucial for safeguarding your skin and overall health. Understanding the UV levels can help you prevent sunburn and reduce the risk of long-term skin issues, especially during the peak sunlight hours when the UV Index soars to a maximum of 11 around midday. With Jiuguan's Cfa climate, characterized by warm summers and mild winters, residents and visitors alike should be aware of the elevated UV exposure risks. By keeping an eye on the UV Index, you can enjoy the sun while protecting your skin from harmful rays.
The UV Index throughout the day reveals a dramatic rise in sun intensity, peaking during the late morning to early afternoon. Starting the day at a modest 2 at 7:00 AM, the index climbs steadily, reaching 11 by 11:00 AM and maintaining that level until 1:00 PM. This signifies a high risk of harm from unprotected sun exposure. Following this peak, the index begins to dip, dropping to 8 by 2:00 PM, and continuing its decline until it falls to 0 by 7:00 PM. With this information, it's crucial to take sun safety precautions—especially during the hours when the UV Index is at its highest!
