In Chongru, China, staying informed about the UV Index is crucial for protecting your skin from harmful ultraviolet rays. Understanding UV levels can help you effectively prevent sunburn and promote long-term skin health, particularly during the peak hours when the index skyrockets—reaching a maximum of 13 at noon. With a Cfa climate that typically features warm summers, the potential for intense sun exposure is high. By monitoring the UV Index, residents and visitors alike can make informed choices about sun protection, ensuring their outdoor activities remain safe and enjoyable.
The UV Index throughout the day reveals a notable peak in solar intensity. Starting gently at 2 at 7:00 AM, it quickly rises as the sun climbs higher. By 10:00 AM, the index hits 10, indicating strong UV exposure, which reaches its maximum of 13 at 12:00 PM—the height of midday sun. A gradual decline follows, bringing the index down to 6 by 3:00 PM, before it dips to a low of 1 by 6:00 PM and finally settles at 0 by 7:00 PM. These fluctuations highlight the importance of sun protection during midday hours when UV levels are at their highest.
