Understanding the UV Index is crucial for residents of Baihua, China, where high levels of ultraviolet radiation can pose significant risks to skin health. With a climate classified as Cwa, the region experiences diverse weather patterns, but it’s essential to stay informed, especially during peak UV hours. Knowing the UV levels can help you take proactive steps to prevent sunburn and other skin-related issues.

From January to February, the UV Index increases from 5 (moderate) to 6 (high), indicating a growing necessity for sun protection. The risk peaks between March and July, where the UV Index reaches 12 (extreme) during May and July, and 11 (extreme) in April, June, and August; these months are particularly critical, with burn times as short as 10 minutes.
