In Guanshui, China, understanding the UV Index is crucial for protecting your skin and maintaining overall health. As the sun's rays can dramatically increase during peak hours, knowing how to gauge UV levels helps you prevent sunburn and long-term skin damage. With a Cwa climate, Guanshui typically showcases hot summers that bring intense sun exposure, peaking at a UV Index of 11 around noon—an alarming level that demands caution. Whether you're planning outdoor activities or simply enjoying a sunny day, being aware of the UV Index can significantly reduce your risk of harmful effects from the sun. Stay informed to keep your skin safe and healthy!
The UV Index throughout the day showcases a clear pattern of rising and falling intensity. Starting at a mild 2 at 7:00 AM, the levels climb steadily, peaking at 11 by noon—the most intense period of sunlight. As the afternoon progresses, the index remains high, tapering off to 10 at 1:00 PM, before gradually descending. By 3:00 PM, it drops to 5, and the evening settles in with indices of 3 at 4:00 PM, and a gentle decline to 1 by 7:00 PM. This progression highlights the importance of sun protection during peak hours—particularly between 10 AM and 2 PM—when the UV exposure is at its highest.

As the seasons change, so does the UV Index, highlighting the importance of sun safety for both visitors and residents. From January to February, the UV levels remain in the moderate range (3-4), allowing for relatively safe outdoor exposure with a burn time of 30 minutes. However, by March, the UV Index escalates to high (6) with a reduced burn time of 25 minutes, signaling a shift. The peak risk occurs from April to August, with UV Index levels reaching very high (9-10) and extreme (11) ratings, particularly in July and August, where the burn time drastically reduces to just 10 minutes. As autumn approaches, UV exposure decreases, dropping to high in October and moderate levels again in November and December. It is crucial for everyone to take appropriate precautions, especially during the high-risk months of April to August, by wearing protective clothing, applying sunscreen frequently, and seeking shade during peak hours to minimize sunburn risks.
