Understanding the UV Index is crucial for residents of Xiangqiao, China, where exposure to harmful ultraviolet rays can lead to skin damage and an increased risk of sunburn. With peak UV levels reaching as high as 11 around midday, it's vital to be mindful of these fluctuations, especially during the sunniest hours. Given Xiangqiao’s humid subtropical climate (Cwa), the potential for intense UV exposure is heightened, underscoring the importance of taking protective measures for optimal skin health.

After this midday intensity, the numbers begin to wane, dropping to 10 at 2:00 PM, then to 8 at 3:00 PM. The afternoon cools off slightly, falling to 5 by 4:00 PM, and ultimately settling back to 3 by 5:00 PM.
