Understanding the UV Index is essential for residents of Biruxong, China, where the climate can intensify sun exposure and elevate risks of harmful UV radiation. Awareness of UV levels not only aids in preventing sunburn but also plays a crucial role in maintaining long-term skin health. With Biruxong's typical mountain tundra climate leading to significant UV spikes—peaking at an alarming 17 from late morning to early afternoon—it's vital to take protective measures during these hours. By staying informed about the UV Index, you can enjoy the outdoors while safeguarding your skin against potential damage.
The UV Index throughout the day shows a dramatic rise in intensity, reaching its peak at 1 PM with a staggering 17. Starting from a modest 1 at 7 AM and 8 AM, the index gradually escalates until it hits 11 by 11 AM, signaling the arrival of intense sunlight. By noon, the UV Index soars to 15, warning of the need for sun protection. The afternoon maintains this high intensity, holding at 17 until 3 PM, before beginning to decline. By 5 PM, it drops to 8, and as the sun sets, the index gradually falls to a safer 2 at 7 PM. It's vital to stay vigilant during those peak hours to avoid harmful exposure!
