Understanding the UV Index is crucial for residents of Noida, India, particularly given the region's Cwa climate which often results in high UV exposure levels. Knowing the UV index can help you take essential precautions to prevent sunburn and maintain skin health, especially during peak hours when the UV index reaches its maximum of 11 from 11:00 AM to 1:00 PM. With an average UV index that climbs throughout the morning and peaks in the afternoon, it’s vital to stay informed and protected from harmful rays to ensure a safe and enjoyable outdoor experience.
The UV Index throughout the day reveals a dramatic rise in sun intensity, peaking during the late morning to early afternoon. Starting the day at a modest 2 at 7:00 AM, the index climbs steadily, reaching 11 by 11:00 AM and maintaining that level until 1:00 PM. This signifies a high risk of harm from unprotected sun exposure. Following this peak, the index begins to dip, dropping to 8 by 2:00 PM, and continuing its decline until it falls to 0 by 7:00 PM. With this information, it's crucial to take sun safety precautions—especially during the hours when the UV Index is at its highest!
