Understanding the UV Index is crucial for residents and visitors in Hongshanyao, China, where the intense sun can pose significant risks to skin health. With peak UV levels soaring to 13 around noon, awareness of these fluctuations helps in sunburn prevention and protecting against long-term damage. Hongshanyao's arid climate (BSk) can lead to increased UV exposure, making it vital to plan outdoor activities around the UV Index to keep your skin safe while enjoying the sunny days. Stay informed, stay safe, and enjoy the sunshine with confidence!
During the early hours of the day, the UV Index begins at a modest 1* at 07:00, gradually rising to 2 by 08:00. However, as the sun climbs higher, the intensity peaks, hitting 10 at 11:00 and soaring to a scorching 13 from 12:00 to 13:00. The afternoon sees a slight decline, with readings of 12 at 14:00 and 10 at 15:00. As the day transitions towards evening, the index decreases further to 7 at 16:00 and concludes with a gentle drop to 2 by 18:00, finally settling back at 1 by 19:00. This UV data highlights the importance of sun protection during peak hours, especially between 10:00 and 14:00, when the sun's power is at its highest.
