Understanding the UV Index is crucial for residents of Jingxi, China, where sun exposure can vary significantly throughout the day. With a humid subtropical climate (Cwa) characterized by hot summers, the risk of sunburn and long-term skin damage increases, especially during peak UV hours. By being aware of the UV levels, particularly when they can soar to as high as 14 around noon, you can better protect your skin's health and enjoy the outdoors safely. Stay informed and proactive to keep your sun exposure—and your skin—healthy!
As the sun rises, the UV Index begins its ascent, starting at a mere 1 at 7:00 AM. A gentle increase follows, reaching 2 by 8:00 AM, before climbing more steeply to hit 4 by 9:00 AM. The intensity peaks sharply at 12:00 PM with a striking 14, coinciding with an hour of sustained high exposure from 11:00 AM to 1:00 PM, where it remains at 11 and 14. The afternoon sees a gradual decline, with the index dropping to 6 by 4:00 PM, then dwindling further to 3 by 5:00 PM. Finally, as the day winds down, the UV Index returns to its morning level, settling at 1 by 6:00 PM and remaining steady until nightfall at 7:00 PM. For those enjoying outdoor activities, it's prudent to seek shade and use sun protection during the peak hours when the UV Index is at its highest.
