In Shuiyang, China, staying informed about the UV Index is crucial for protecting your skin from harmful ultraviolet rays. Understanding UV levels helps residents and visitors alike prevent sunburn and long-term skin health issues. With a Cfa climate characterized by hot summers and varying sun exposure, it's essential to be mindful of peak UV times, especially between 10 AM and 2 PM when indices can reach a high of 11. By paying attention to the UV Index, you can enjoy the sun safely while minimizing potential health risks.
The UV Index data reveals a clear pattern in solar exposure throughout the day. Morning rays begin gently, with a maximum of 2 at 07:00, steadily rising to 4 by 08:00. As the sun climbs higher, the index peaks at an impressive 11 at 12:00, indicating a moment of intense UV radiation. Temperatures remain elevated with a 10 at 11:00 and 13:00, before gradually declining to 8 by 14:00. The afternoon light softens, dropping to 6 by 15:00, then continues to retreat as the sun sets—falling to 3 at 16:00, 2 at 17:00, and reaching 1 by 18:00 and 19:00. This data underscores the importance of protecting your skin during the peak hours, especially between 10:00 and 14:00, when the UV Index is at its highest.

As the seasons change, so does the UV Index, reflecting the varying intensity of ultraviolet radiation throughout the year. January and December experience moderate UV levels, with burn times of 30 minutes, while February sees an increase to high levels, prompting reduced exposure of just 25 minutes. The high-risk months are from March to August, where the UV Index peaks at 11 during June and July, classifying these months as having extreme exposure risk and requiring careful management of sun exposure, with a burn time of only 10 minutes. Visitors and residents should ideally plan outdoor activities for early mornings or late afternoons, seek shade during peak sun hours, and use sun protection, such as broad-spectrum sunscreen, hats, and sunglasses, particularly during March through August when burn times are significantly shorter. As fall and winter approach, the UV index gradually decreases, making outdoor time less risky, but caution is still advised during the transitional months.
