In Da'an, China, being aware of the UV Index is crucial for protecting your skin and overall health. Understanding UV levels helps you take proactive measures against sunburn and long-term skin damage, especially during the peak hours when exposure risks are highest. With a Cfa climate, Da'an experiences significant UV exposure, particularly from 10 AM to 2 PM, when the UV Index can soar to 12. By monitoring the UV Index, you can enjoy the sunny days while safeguarding your skin from harmful radiation.
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.
