In Pulau Pramuka, Indonesia, staying aware of the UV Index is crucial for protecting your skin and overall health. Understanding UV levels helps prevent sunburn, reduces the risk of skin damage, and promotes long-term wellness. With a tropical climate characterized by high sun exposure, Pulau Pramuka experiences significant UV index spikes, reaching levels as high as 11 during midday hours.

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.
