In Changshou, China, being aware of the UV Index is crucial for maintaining your skin health and preventing sunburn. The UV Index indicates the strength of ultraviolet radiation from the sun, which can lead to skin damage if exposure is unprotected, especially during the peak hours of 11:00 AM to 1:00 PM when levels can reach as high as 11. With Changshou's Cfa climate, characterized by warm summers, residents and visitors alike should understand the typical UV exposure risks to safeguard their skin while enjoying outdoor activities. Stay informed and protect yourself under the sun!
The UV Index throughout the day demonstrates a significant rise as the sun reaches its zenith. Starting from a mild 1 at 07:00, the intensity escalates rapidly, hitting 3 by 08:00 and climbing to a peak of 11 at 12:00—the moment when sun protection is imperative. As the afternoon progresses, the index gradually declines, showing values of 10 at 13:00, 9 at 14:00, and 7 at 15:00. By 16:00, it drops to 4, and by the evening, the UV exposure wanes, returning to 1 by 18:00 and 19:00. This pattern underscores the importance of vigilance during midday hours when UV radiation poses the highest risk. Remember to stay shaded and apply sunscreen generously!
