In Belah Lor, Indonesia, being aware of the UV Index is crucial for protecting your skin and overall health. The UV Index indicates the strength of ultraviolet radiation from the sun, which is vital for sunburn prevention and reducing the risk of skin damage. With a tropical climate characteristic of high UV exposure, especially from late morning to early afternoon, understanding the UV levels can help residents and visitors alike enjoy the sun safely. At peak times, such as around 12 PM when the UV Index reaches as high as 12, knowing how to protect yourself becomes essential. Stay informed, stay safe, and make the most of your time in the sun!
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!
