Understanding the UV Index is crucial for residents of Yanjiang, China, as it provides vital information for protecting your skin from the harmful effects of ultraviolet radiation. Knowing the UV levels helps you take proactive steps to prevent sunburn and maintain long-term skin health, especially in a region characterized by a Dwb climate that can expose you to high UV levels, particularly during late morning and early afternoon. With the index peaking at 8 around noon, awareness of these fluctuations can make a significant difference in optimizing your sun safety practices. Stay informed and enjoy the sun responsibly!
The UV Index today presents a dynamic pattern, peaking between 11:00 AM and 12:00 PM with a maximum value of 8, indicating a high risk of harm from unprotected sun exposure. As the day begins, the index starts at a modest 3 at 7:00 AM, gradually rising to 4 by 8:00 AM. By 9:00 AM, it climbs to 6, and shortly after, by 10:00 AM, it reaches 7. However, a steady decline is observed post-noon, dropping to 6 at 2:00 PM, further decreasing to 4 by 3:00 PM, and then tapering off significantly to 1 by 4:00 PM and beyond. This trend emphasizes the importance of seeking shade or applying sun protection especially during peak hours. Stay safe and enjoy the sunshine responsibly!

Throughout the year, the UV Index exhibits significant seasonal changes that affect sun exposure risks. From January to February, the UV Index remains low (1-2), allowing for a safer outdoor experience with a burn time of up to 45 minutes. As spring approaches in March and April, the UV levels rise to moderate (4-5), shortening the safe exposure to 30 minutes. The onset of summer, particularly May through August, marks the period of highest risk, with UV Index values reaching 8 and a burn time plummeting to just 15 minutes—this is the time for extreme caution. Moving into fall, the Index decreases to moderate levels again in September and October, allowing for safer outdoor activities with a 30-minute burn time, before returning to lower levels by November and December (UV Index 1-2). Visitors and residents are strongly advised to take protective measures—such as sunscreen and protective clothing—especially during the high-risk months of May to August to minimize the risk of skin damage.
