In Dayang, China, being aware of the UV Index is essential for maintaining healthy skin and preventing sunburn. With its Dwb climate, characterized by distinct seasons and significant temperature variations, Dayang experiences fluctuating UV levels that can pose risks, especially in summer months.

As the seasons change, so too do the UV levels, significantly impacting both visitors and residents. January starts with a moderate UV Index of 4, allowing for a burn time of 30 minutes, but by February, the risk escalates to a high UV Index of 6, reducing burn time to 25 minutes. The real concern arises from March through September, where the UV Index reaches very high and extreme levels, peaking at 13 in June. During this critical period, recommended burn times drop to as little as 10 minutes. Particularly, the months of May to September are classified as high-risk, necessitating precautionary measures such as sunscreen, protective clothing, and limited sun exposure, especially during peak hours. As autumn approaches, the UV levels decrease, with October reflecting a very high index of 8 before returning to moderate levels by November and December. Residents and visitors should remain vigilant and adapt their sun protection strategies accordingly throughout the year, especially during summer months.
