Understanding the UV Index is crucial for residents and visitors in Nanjie, China, as it plays a vital role in safeguarding skin health and preventing sunburn. With the region's Cfa climate, which typically features warm summers and moderate humidity, UV radiation levels can soar, especially during midday hours. For instance, the UV Index peaks at a striking 13 around noon, indicating an extreme risk of harm from unprotected sun exposure. By keeping a close eye on UV levels, you can take proactive measures to enjoy the sun safely and protect your skin from long-term damage.
The UV Index peaks dramatically throughout the day, starting from a gentle 1 at 07:00 and gradually rising to an impressive 13 by 12:00. This midday surge marks the day’s highest UV exposure, with levels reaching 11 at 11:00 and 13:00. As the sun begins to descend, the index declines smoothly, tapering back to 8 at 15:00, then 5 at 16:00, and finally settling down to 1 by 18:00 and 19:00. It's essential to stay protected, especially during those peak hours, as the sun’s rays can be quite fierce!
