Understanding the UV Index is crucial for residents and visitors in Juru, Brazil, where the climate typically falls under the tropical Aw category, exposing individuals to varying levels of UV radiation throughout the day. Awareness of these UV levels is essential for effective sunburn prevention and maintaining overall skin health. With the UV Index peaking at an intense 11 between 11:00 AM and 12:00 PM, Juru's sun can pose significant risks, making it vital to stay informed and take protective measures during peak sun hours. As you enjoy the beautiful Brazilian outdoors, remember that knowing the UV Index can help you protect yourself and your loved ones from harmful sun exposure.
The UV Index today paints a compelling picture of sunlight intensity as the day unfolds. Starting mildly at 1 around 07:00, it quickly ramps up to a moderate level of 4 by 08:00. As the sun climbs higher, 09:00 sees the index soar to 7, transitioning into the high range with a peak of 11 at both 11:00 and 12:00. This pronounced exposure indicates a strong need for sun protection during these hours. As afternoon approaches, the index begins to gracefully decline, dipping to 9 by 13:00, then tapering off to 6 at 14:00. Later in the day, the intensity eases further, dropping to a 3 at 15:00, and finally settling back to 1 by 16:00 and later to 0 after 18:00. Remember to stay cautious and shield yourself during those peak hours!
