In Purabaya, Indonesia, being aware of the UV Index is crucial for safeguarding both your skin and overall health. Understanding UV levels not only helps in preventing sunburns, but it also plays a significant role in long-term skin health, reducing the risk of skin cancer and premature aging. With Purabaya's tropical climate, the UV Index can reach significant heights, peaking at an intense 11 around midday.

As the afternoon progresses to 13:00, the index begins to decline, dropping back to 9 at this hour. By 14:00, it eases further to 7 and continues its descent, settling at 4 by 15:00. As the day winds down, the readings fall to 2 by 16:00, tapering to a gentle 1 at 17:00, and finally retreating to 0 by 18:00 and 19:00. This journey through the UV Index highlights the importance of sun protection, particularly during those peak hours when it reaches its zenith.
