Understanding the UV Index is crucial for residents of Rongcheng, China, as it provides valuable information about the sun's harmful ultraviolet (UV) radiation levels throughout the day. With high UV ratings peaking at 12 around noon, awareness is essential for preventing sunburn and maintaining optimal skin health. Rongcheng’s Cfa climate ensures ample sunshine, but this also brings increased exposure risks, particularly during the late morning and early afternoon hours.
