Understanding the UV Index is crucial for residents and visitors in Limin, China, where the climate's Dwb designation indicates a significant risk of ultraviolet (UV) exposure, especially during peak hours. With UV levels soaring to 11 by noon and even hitting 12 in the early afternoon, awareness of these fluctuations is essential for sunburn prevention and overall skin health. Knowing when the UV Index is high can help you take necessary precautions to protect yourself and your loved ones from harmful sun exposure, making it imperative to stay informed about daily UV levels in this vibrant locale.
The UV Index climbs steadily throughout the morning, peaking at 12 around 1:00 PM, signaling a strong potential for skin damage without protection. Starting from a low of 1 at 7:00 AM, the index escalates, reaching a moderate 8 by 10:00 AM. As the sun hits its zenith, the index then soars to an impressive 11 at noon, before slightly dipping to 10 by 2:00 PM. By late afternoon, the index begins to decline, dropping to 5 by 4:00 PM, and tapering off to 3 by 5:00 PM, with the evening returning to a gentle 1. It's essential to stay covered and protected during those peak hours when UV exposure is at its highest!
