Understanding the UV Index is crucial for the residents of Sungai Raya, Indonesia, where the tropical climate brings with it a high risk of harmful ultraviolet radiation. Being aware of UV levels is essential not just for preventing painful sunburns but also for protecting long-term skin health.

As evening approaches, the levels decrease to 2 at 17:00 and back to 1 by 18:00, finally settling at a relaxing 0 by 19:00.
