Understanding the UV Index is crucial for the residents of Parauna, Brazil, where the sun’s intensity can pose significant health risks throughout the year. With a climate characterized by long, sunny days typical of the Aw climate zone, knowing the UV levels helps you take proactive steps in preventing sunburn and protecting your skin health. As UV exposure peaks during the midday hours, particularly between 11 AM and 1 PM, being informed allows you to enjoy the vibrant outdoor life of Parauna while minimizing the risk of damaging rays. Stay safe under the sun by keeping an eye on the UV Index!
Get ready for a sunny day as the UV Index climbs throughout the morning and peaks in the afternoon! Starting gently at a low level of 1 at 07:00 and 08:00, the intensity begins to rise steadily. By 09:00, it reaches 3, and things heat up significantly by 10:00 with a 5. The real sun-seeker moments hit between 11:00 and 13:00, where the UV Index soars to a maximum of 9, indicating a high risk of harm from unprotected sun exposure.

By the time evening arrives, the UV Index retreats to a low level of 1 at 17:00, finally fading to 0 after 18:00. Remember to lather on sunscreen and stay hydrated during those peak hours!
