Understanding the UV Index in Wengshan, China is crucial for safeguarding your skin and overall health. With the region's humid subtropical climate (Cfa), residents face significant UV exposure, especially during the peak hours when the index can soar to a critical level of 12 around noon. Being aware of these UV levels is essential for preventing sunburns and reducing long-term skin damage. As Wengshan's UV intensity fluctuates throughout the day, knowing when to seek shade or apply sunscreen can make all the difference in maintaining healthy skin while enjoying the vibrant outdoors.
The UV Index provides a vital insight into sun exposure throughout the day, peaking during the late morning to early afternoon hours. At 07:00, it starts off low at 2, but by 08:00, it rises to 4, indicating increasing sun intensity. The real surge happens between 09:00 and 12:00, where it climbs dramatically to a maximum of 12 at 11:00 and 12:00. As the sun begins to dip after 13:00, the index gradually decreases to 11 at 1 PM and gently tapers off to 9 at 2 PM. By 3 PM, it continues to decline to 6, and by the evening, it reaches a minimal 1 at both 5 PM and 6 PM, finally falling to 0 by 7 PM. This hourly breakdown urges us to protect our skin during the peak hours, especially when the index hits its zenith.

As the seasons change, so do the UV levels, with high-risk months peaking from March to September, where the UV Index consistently reaches extreme levels of 11 to 13. January starts with a high UV Index of 6, which increases to a very high 8 in February, then sharply escalates to extreme values for the following months. During the peak summer months of June, July, and August, a UV Index of 13 indicates a burn time of just 10 minutes. As autumn begins, UV levels gradually decrease but remain significant, dropping to 9 in October. To ensure safety, it is advised that visitors and residents take precautions during high UV periods by wearing sunscreen, protective clothing, and seeking shade during peak hours, particularly from March through September. In contrast, burn times of 25 minutes in January, November, and December suggest relatively lower UV risks during those months.
