Understanding the UV Index is crucial for residents of Koch Bihar, India, where the subtropical climate can elevate ultraviolet (UV) exposure levels, especially during peak sun hours. Knowing the daily UV levels can help you take proactive measures against sunburn and skin damage, ensuring your skin health remains a priority. With peak UV Index readings soaring to 10 around midday, it's essential to stay informed and protect yourself during high-risk periods. Especially in a region that experiences significant sunlight, keeping an eye on the UV Index will empower you to enjoy the outdoors safely while minimizing exposure to harmful rays.
The UV Index throughout the day shows a clear peak in the late morning, with values reaching a maximum of 10 between 10:00 AM and 12:00 PM.
