In Qiantan, China, being aware of the UV Index is essential for protecting your skin against harmful ultraviolet rays. Understanding UV levels is crucial for preventing sunburn and maintaining long-term skin health, especially in a region where the climate is characterized as Cfa, leading to warm summers that may expose residents to heightened UV risks. With peak UV levels reaching up to 11 around midday, it’s vital to stay informed about daily UV fluctuations, allowing residents to take proactive measures and enjoy the outdoors safely.
The UV Index throughout the day reveals a dramatic rise in sun intensity, peaking during the late morning to early afternoon. Starting the day at a modest 2 at 7:00 AM, the index climbs steadily, reaching 11 by 11:00 AM and maintaining that level until 1:00 PM. This signifies a high risk of harm from unprotected sun exposure. Following this peak, the index begins to dip, dropping to 8 by 2:00 PM, and continuing its decline until it falls to 0 by 7:00 PM. With this information, it's crucial to take sun safety precautions—especially during the hours when the UV Index is at its highest!

As the seasons change, so does the UV Index, significantly impacting sun exposure risks throughout the year. The months of March to September present the highest UV levels, peaking in May and June with an extreme index of 11-12 and a burn time of just 10 minutes. Specifically, March and April also carry very high values (9-10), while October briefly returns to a very high index of 8. Thus, visitors and residents should take extra precautions from March through October, utilizing sunscreen, wearing protective clothing, and seeking shade, particularly during peak sunlight hours. With January and February having a high index but longer burn times, individuals should also remain vigilant during these months. In contrast, November and December see a drop to moderate and high levels, allowing for a bit more leeway, but sun protection should still be considered.
