Understanding the UV Index is crucial for residents and visitors of Tapiramuta, Brazil, where the tropical Aw climate brings about high sun exposure. As UV levels can spike dramatically throughout the day—reaching a maximum of 10 from 11:00 AM to 12:00 PM—being aware of these fluctuations is key to preventing sunburn and promoting long-term skin health. By monitoring the UV Index, you can take proactive measures to enjoy the sun safely, minimizing potential risks associated with excessive exposure and making the most of Tapiramuta's beautiful sunny days.
From sunrise to sunset, the UV Index tells a compelling story of the day's sun. Starting at a gentle 1 at 07:00, the UV levels gradually rise, peaking at an intense 10 by 11:00 and 12:00. This signifies a critical window for sun safety, as exposure during these hours demands caution. Just after noon, the index begins to decline, slipping to 9 at 13:00 and further down to 6 by 14:00. As the evening approaches, the numbers diminish swiftly to 4 at 15:00, and finally taper off to a relaxing 1 by 17:00, with complete relief from UV exposure by 19:00 when it hits 0. It's clear that being sun-smart is essential especially during the midday peak!
