Understanding the UV Index is crucial for residents of Mingguang, China, as it directly impacts skin health and sunburn prevention. With a warm Cfa climate that exposes residents to varying UV levels throughout the day, being informed about UV risks can help you protect your skin from harmful effects. For instance, during peak hours—especially from 10 AM to 1 PM—the index can soar to 10, indicating a very high risk of harm from unprotected sun exposure. By keeping an eye on the UV Index, you can enjoy the sun safely while minimizing the risk of skin damage.
The UV Index throughout the day showcases a compelling rise and fall in sunlight intensity. Starting the morning at a modest 2 at 07:00, it escalates to a more significant 3 by 08:00 and then reaches its peak between 11:00 and 13:00, where it maintains a high of 10. As the afternoon progresses, the index gradually declines, dipping to 5 at 15:00 and further down to 3 by 16:00. By evening, the UV levels drop dramatically to 1 at 18:00 and into 0 by 19:00, signaling a retreat of the sun's intensity. This pattern emphasizes the importance of sun safety during the midday hours when UV exposure is at its highest.
