Understanding the UV Index is essential for residents and visitors in Bozhou, China, where the sun can be both a source of warmth and a potential risk to skin health. With the city experiencing a Cwa climate, characterized by hot, humid summers, UV levels can spike significantly, particularly during midday hours. Awareness of these UV levels is crucial for sunburn prevention and protecting long-term skin health, especially around peak times from 11:00 AM to 1:00 PM, when the Index often reaches as high as 11. By staying informed about the UV Index, you can take necessary precautions to enjoy the sun safely while minimizing the risk of skin damage.
At dawn, the UV Index begins its gradual ascent, peaking at 1 by 7:00 AM. As the sun rises higher in the sky, it quickly reaches 3 by 8:00 AM and 5 by 9:00 AM, signaling that it's time to apply some sunscreen. The intensity builds throughout the morning, hitting 7 at 10:00 AM and skyrocketing to its maximum of 11 by 1:00 PM, making this the most crucial time to protect your skin. As the afternoon progresses, the index dips to 9 at 2:00 PM before gradually decreasing to 6 at 3:00 PM, 4 at 4:00 PM, and then tapering off to 2 by 5:00 PM. Finally, as the sun begins to set, the UV Index returns to a gentle 1 by 18:00 PM, letting you know it's safe to relax outdoors without as much concern.
