Understanding the UV Index is crucial for residents of Puji, China, where the unique Cwb climate can lead to varying UV exposure throughout the day. With peak UV levels climbing as high as 15 around midday, awareness of these measurements is essential for preventing sunburn and promoting long-term skin health. By knowing when to seek shade and apply sunscreen, you can effectively protect yourself and your loved ones from the harmful effects of ultraviolet radiation, making your time outdoors in Puji both enjoyable and safe.
The UV Index reveals a dramatic rise in solar intensity throughout the day, starting from a gentle 1 at 07:00, which gradually escalates as the sun climbs higher.
