Understanding the UV Index is crucial for residents of Putang, China, where the sun's rays can be particularly intense. With a climate classified as Cfa, the risk of skin damage increases significantly during peak hours, especially from 10 AM to 2 PM, when UV levels soar to 10—indicating an extreme level of solar radiation. By keeping an eye on the UV Index, residents can effectively prevent sunburn and protect their skin health, ensuring they enjoy the sunny days while minimizing the harmful effects of UV exposure. Whether soaking up the sun or engaging in outdoor activities, awareness of these levels is essential for maintaining safe and healthy habits under the sun.

By 09:00, the index reaches 6, but it truly peaks at 11:00 and 12:00, boasting a robust 10—a sign to seek shade or wear protective gear.

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.
