In Hongshi, China, staying informed about the UV Index is vital for protecting skin health and preventing sunburn. Understanding UV levels helps residents and visitors safeguard themselves from the harmful effects of ultraviolet radiation, particularly during the sun's peak hours. Given Hongshi's Dwb climate—characterized by warm summers and cold winters—UV exposure can be significant, especially between 10:00 AM and 2:00 PM, when the UV Index spikes to a maximum of 8. This awareness not only encourages safe outdoor activities but also fosters a more health-conscious community.
The UV Index rises with the sun, peaking as the day unfolds. At 07:00, it begins at a mild 2, but by 08:00, it climbs to 4. The real heat arrives by 10:00, reaching a strong 7, and by 11:00 and 12:00, it hits its highest point of 8—a moment to seek shade or slather on that sunscreen! As the afternoon progresses, the index dwindles, dropping to 5 by 14:00, and continuing to decline through the late afternoon with 3 at 15:00, 2 at 16:00, and tapering off to a low of 1 by 17:00 and 18:00. Finally, as the day fades, the UV Index falls to 0 by 19:00, signaling a much safer time to enjoy the outdoors without worries. Remember to protect your skin when the sun is at its zenith!
