Being aware of the UV Index is crucial for residents of Rondonopolis, Brazil, where the tropical climate brings intense sun exposure. Understanding UV levels can significantly impact your skin health by helping to prevent painful sunburns and long-term damage.

By staying informed, you can take proactive measures to protect yourself and enjoy the sun safely.

However, as the morning progresses, the index climbs sharply, reaching 3 by 08:00 and hitting 6 by 09:00. The peak exposure occurs from 11:00 to 12:00, where it reaches its maximum of 10, indicating a high risk for harm from unprotected sun exposure. By the afternoon, a gradual decline begins: 8 at 13:00, followed by 5 at 14:00, before tapering off to 3 at 15:00. As the day winds down, UV levels decrease to 1 by 16:00 and drop to 0 after 18:00, making late evening a soothing time to relax outdoors without sun concerns. Always remember to protect your skin during those peak hours!
