Understanding the UV Index is crucial for residents and visitors in Shelby, Peru, where exposure to harmful ultraviolet rays can vary significantly throughout the day. With temperatures often influenced by the region's ET climate zone, awareness of UV levels is key to preventing sunburn and protecting skin health. For instance, between 10 AM and 2 PM, UV Index levels soar to a high of 14, signaling the importance of sun safety measures during peak hours. By staying informed about UV risks, you can enjoy the beautiful Shelby sun while keeping your skin safe and healthy.
As the sun rises, the UV Index steadily climbs, starting at a moderate 1 at 07:00 and reaching a significant 14 by 12:00, marking the peak of the day. Between 10:00 and 13:00, UV levels soar, peaking at 13 for a few hours, a reminder to stay protected under the midday sun. However, as the afternoon wanes, the index drops sharply, down to 6 by 15:00, before continuing to decline to 3 at 16:00 and ultimately returning to a safe 0 by 18:00. This data underscores the importance of being sun-smart during peak hours when the risk of UV exposure is at its highest.
