In Luanzhou, China, being aware of the UV Index is crucial for protecting your skin and maintaining overall health. Understanding UV levels helps prevent sunburn, skin damage, and long-term health risks associated with excessive sun exposure. With a Dwa climate, residents and visitors alike experience intense UV radiation, particularly during midday hours when the index can soar to 9. By keeping an eye on the UV Index and adjusting outdoor activities accordingly, you can enjoy the beautiful weather while safeguarding yourself against harmful effects of UV rays.
The UV index demonstrates a clear peak in intensity throughout the day, starting at a mild 2 at 07:00. As the sun rises higher, the index climbs steadily, reaching 3 at 08:00 and making a significant leap to 6 by 09:00. The real surge occurs between 10:00 and 12:00, where it hits 8 and stays at a critical 9 until 13:00. This high exposure means sun protection is crucial during these hours. As the afternoon progresses, the UV index gradually declines, dropping to 7 at 14:00 and then tapering off to 5 at 15:00, before falling further to 3 by 16:00. By the evening, the index diminishes to 2 at 17:00, and settles at a low 1 for the remainder of the day. This fluctuating UV exposure highlights the importance of midday sun safety, ensuring that we're well-informed and adequately protected during the peak hours.
