In Quankou, China, understanding the UV Index is crucial for protecting your skin and overall health. With UV levels reaching a peak of 15 during midday, residents and visitors need to be informed about potential sunburn and long-term skin damage. The region's ET climate features strong sunlight, particularly in the warmer months, making it essential to stay vigilant. By grasping how UV exposure varies throughout the day, you can enjoy the outdoors safely while minimizing risks associated with harmful ultraviolet radiation. Remember, knowledge is your best defense against the sun!
The UV Index climbs steadily throughout the morning, beginning at a mild 1 at 7:00 AM and reaching a moderate 2 by 8:00 AM. As the sun rises higher in the sky, the intensity escalates dramatically, peaking at a striking 15 between 1:00 PM and 2:00 PM. This period represents the pinnacle of UV exposure, necessitating precautionary measures for outdoor activities. Following this peak, the index gradually declines, dropping to 12 at 3:00 PM and further to 3 by 6:00 PM, before settling back to a safe 1 at 7:00 PM. With these fluctuations in UV levels, it’s essential to stay informed and protect your skin, especially during midday hours.
