Understanding the UV Index in Shijing, China is crucial for protecting your skin and overall health against harmful ultraviolet rays. With levels peaking at 11 to 13 during midday hours, the risk of sunburn and long-term skin damage becomes significant, making it essential to stay informed about these fluctuations. Shijing, characterized by its humid subtropical climate, experiences high UV exposure, particularly in the summer months. Being aware of the UV Index not only empowers residents and visitors to take preventive measures but also fosters a culture of skin health awareness, ensuring a safe and enjoyable experience under the sun.
The UV Index during the day reveals a notable peak in sun exposure. Starting at 07:00 with a gentle 1, it gradually climbs to 2 by 08:00. As the sun rises higher, the index surges dramatically, hitting 5 at 09:00, and reaching a striking 8 by 10:00. The intensity peaks at 12:00 with a scorching 13, remaining high until 13:00. After that, it starts to decline, returning to 11 at 14:00 and falling to 8 by 15:00. As the afternoon wanes, the index drops to 5 at 16:00, and finally settles back to 1 by 18:00 and 19:00. This data highlights the importance of sun safety measures during the midday hours when UV exposure is at its highest.

The UV Index experiences significant seasonal fluctuations, with the highest values observed from March through October. During these months, particularly from May to August, the UV Index peaks at 13 to 14, indicating an extreme exposure category, with a burn time as short as 10 minutes. The high-risk months are therefore identified as March to August, where spending too much time in direct sunlight without protection can lead to severe skin damage. In contrast, the risk decreases in January and February (UV Index of 8 to 10, very high) and again in November and December, where lower UV levels (especially in December at 7) allow for longer safe exposure times (up to 25 minutes). Visitors and residents should take protective measures such as wearing sunscreen, hats, and protective clothing during peak months, and seek shade whenever possible to minimize the risk of UV exposure.
