Understanding the UV Index is crucial for residents of Gucheng, China, especially given the area's Dwb climate, characterized by hot summers and cold winters. With peak UV levels reaching as high as 12 during midday, awareness of these levels is essential for preventing sunburn and protecting skin health.
