Understanding the UV Index is crucial for residents and visitors of Nankun, China, as it serves as a vital tool for protecting your skin health. With the region's Aw climate, characterized by hot summers and significant sunlight exposure, awareness of UV levels can help prevent sunburn and long-term skin damage. During peak hours, particularly from 11:00 AM to 1:00 PM, the UV Index reaches extreme levels, climbing as high as 14, indicating a high risk for harm. By staying informed about these conditions, you can enjoy the sun safely while safeguarding your skin against potential hazards.
The UV Index reveals a dynamic range of exposure throughout the day, starting gently at 1 by 07:00 and climbing steadily to a peak of 14 between 12:00 and 13:00. As the sun reaches its zenith, safety precautions are crucial, especially during the hour of 11:00 when the index hits 11. After the intense midday sun, the index gradually descends, dropping to 9 at 15:00, and mellowing out to 1 by 19:00. This clear pattern underscores the importance of sun protection during the most intense hours, ensuring a safe and enjoyable time outdoors.
