Understanding the UV Index is crucial for residents and visitors in Sungai Segajah, Indonesia, as it plays a vital role in sunburn prevention and overall skin health. The region's tropical climate exposes individuals to varying UV levels throughout the day, peaking dangerously at midday when the index reaches as high as 14.
