Understanding the UV Index is crucial for residents of Hehu, China, where the climate can lead to varying levels of ultraviolet radiation throughout the day. As daily UV exposure peaks around noon, with levels reaching a staggering 13, awareness of UV levels can be a game-changer in preventing sunburn and promoting long-term skin health. Given Hehu’s Cfa climate, which features humid subtropical conditions, it’s essential to stay vigilant against the risks of overexposure, especially during the summer months when the sun is strongest. Stay informed and protect your skin by checking the UV Index regularly!
The UV Index today presents a compelling story of rising sun intensity. Starting the day at a modest 2 by 7:00 AM, the levels climb steadily, peaking at a striking 13 from 12:00 PM to 1:00 PM—a reminder to stay protected! As the afternoon sun begins to wane, the UV Index drops to 10 by 2:00 PM before sliding down to 7 at 3:00 PM. By late afternoon, the index reduces significantly to 4 at 4:00 PM, and continues to fall, reaching 1 by 6:00 PM and finally settling at 0 after sunset at 7:00 PM. Remember to take precautions during the peak hours, especially between 11:00 AM and 1:00 PM, when the sun is at its strongest!
