Understanding the UV Index is essential for the residents of Liuheng, China, as this simple measure can help protect your skin from harmful ultraviolet rays. The UV Index informs you about the intensity of sun exposure, enabling you to take necessary precautions to prevent sunburn and safeguard your overall skin health. With Liuheng's Cfa climate, characterized by warm summers, the risks of high UV levels are particularly pronounced; during peak hours such as 11:00 and 12:00, the Index can soar to an extreme level of 11. By staying informed about UV levels, you can enjoy the sun safely while minimizing potential long-term skin damage.
The UV Index throughout the day presents a dynamic picture of sun exposure. As early as 7:00 AM, the index starts at a mild 2, ramping up to a moderate 4 by 8:00 AM. The sun's intensity peaks around 11:00 AM and 12:00 PM with a striking 11, marking the height of caution for outdoor activities.
