Understanding the UV Index is crucial for residents of Huangyang, China, where sunny days are abundant in the Cwa climate zone, exposing locals to elevated UV radiation levels. Knowing the UV index not only helps in preventing sunburn and protecting skin health but also empowers you to enjoy the outdoors safely. With peak UV levels reaching as high as 12 during midday, it’s essential to monitor daily fluctuations to minimize risks and maximize your time in the sun while keeping your skin safe.
At 07:00 AM, the UV Index starts low at 1, perfect for early risers. As the sun climbs higher, it peaks at 12 between 12:00 and 1:00 PM, signaling intense sun exposure—wear sunscreen! From 2:00 PM onwards, the index gradually declines, dropping to 3 by 5:00 PM. As the day winds down, the UV Index returns to the safe zone of 1 by 6:00 PM, allowing evening activities without worry. Remember, the highest UV levels occur during midday, so plan accordingly to protect your skin!
