Understanding the UV Index is crucial for residents and visitors of Puerto Rosario de Laberinto, Peru, where the sun shines brightly in its tropical climate. With UV levels peaking at 10 around noon, knowledge of these fluctuating intensities is vital for sunburn prevention and lasting skin health. As UV exposure risks escalate during peak hours—especially between 10:00 AM and 2:00 PM—being aware of the local UV Index can help you protect yourself and enjoy the sunny days comfortably and safely.
From 07:00 to 19:00, the UV Index shifts dramatically throughout the day, reaching its peak at 12:00 with a formidable score of 10.

The sun's rays are most potent from 11:00 to 13:00, where caution is advised if you're out and about. Post-12:00, there's a gradual decline, winding down to a 3 at 15:00, 1 by 17:00, and finally dropping to 0 by 19:00 as daylight fades. Remember, during those peak hours, it’s wise to seek shade and protect your skin!
