In Canindé de São Francisco, Brazil, understanding the UV Index is crucial for safeguarding your skin against harmful ultraviolet rays. The high levels of UV exposure, particularly between 10:00 AM and 2:00 PM, can lead to severe sunburn and long-term skin health issues if not properly managed. With its semi-arid climate, the region experiences intense sunlight, making UV awareness even more essential for residents and visitors alike. By keeping an eye on daily UV levels, you can enjoy the beautiful outdoors while protecting your skin's health and vitality.
The UV Index shows a dynamic pattern throughout the day, starting at a gentle 2 at 7:00 AM and gradually rising to a peak of 12 by 12:00 PM. This indicates a high risk of harm from unprotected sun exposure, especially during the midday hours when the sun is strongest. As the afternoon progresses, the index begins to decline, dropping to 6 by 2:00 PM and then further to 3 by 3:00 PM. By 4:00 PM, it decreases to a minimal level of 1, eventually settling at 0 by 6:00 PM and beyond. For those planning outdoor activities, it's crucial to protect your skin during those peak UV hours from 10:00 AM to 1:00 PM!
