In Hongtian, China, being aware of the UV Index is crucial for protecting your skin and overall health. Understanding the UV levels can help you prevent sunburn and long-term skin damage, especially during the peak hours when the index soars, with a maximum of 13 around noon. The Cfa climate in Hongtian, characterized by warm summers, increases UV exposure risks, making it essential to stay informed.

As the afternoon progresses, the intensity begins to wane, dropping to 10 by 2:00 PM and then descending steadily to 7 at 3:00 PM, 4 at 4:00 PM, and eventually dwindling to a safe 1 by 6:00 PM. After 7:00 PM, the UV level flatlines at 0, marking the end of peak sun exposure. Remember, during those peak hours, especially from 10 AM to 2 PM, it's vital to prioritize skin safety!
