Understanding the UV Index is crucial for residents and visitors in Qiantan, China, where the sun’s powerful rays can pose significant risks, especially during peak hours. Awareness of UV levels not only helps in preventing sunburn but also plays a vital role in maintaining long-term skin health. With a humid subtropical climate, Qiantan experiences intense UV exposure, particularly around midday when indices can soar to 12. Staying informed about these levels can empower individuals to enjoy the outdoors safely while minimizing potential harm from the sun’s radiation.
As the sun rises, the UV Index begins its ascent, reaching a maximum of 12 at noon, indicating a high risk of harm from unprotected sun exposure. From 07:00 with a mild level of 2, it climbs gradually, hitting 9 by 10:00 and peaking at 11 at 11:00. The sun’s intensity starts to wane in the afternoon; it drops to 8 at 14:00 and continues to decrease, allowing for a more manageable 6 at 15:00. By late afternoon, the UV Index diminishes further, ending the day at a safe 0 by 19:00. To enjoy the outdoors during the peak hours, it’s essential to take proper precautions to protect your skin from the sun’s rays.

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.
