Awareness of the UV Index in Shizhu, China, is essential for protecting your skin and maintaining overall health. Understanding UV levels can significantly reduce the risk of sunburn and long-term skin damage, making it crucial for everyone, from outdoor enthusiasts to casual sun-seekers. With Shizhu’s Cfa climate, characterized by hot summers and moderate sunlight exposure, awareness of UV risks is particularly important. The UV Index peaks at 12 around noon, presenting a high risk for harm, so staying informed is key to enjoying the sun safely and responsibly.
At sunrise, the UV Index begins at a gentle 2 by 07:00, but as the sun rises higher, the intensity quickly escalates. By 09:00, it reaches a moderate 7, signaling outdoor enthusiasts to apply sunscreen. The peak comes at 11:00 and 12:00, where the index peaks at a striking 12, indicating very high levels of UV radiation. As the afternoon progresses, the index gradually decreases, dipping to 8 by 14:00 and further dropping to 5 by 15:00. In the late afternoon and evening, the UV Index retreats to 3 by 16:00, finally settling at 1 by 17:00 and fading to 0 after 19:00. This daily cycle highlights the importance of sun safety during those peak hours!
