Understanding the UV Index in Penyabangan, Indonesia is crucial for anyone looking to protect their skin from harmful ultraviolet radiation. With its tropical climate, the region experiences significant UV exposure, especially during midday hours when values can peak at a striking 10. Awareness of these levels is essential for effective sunburn prevention and maintaining overall skin health. By monitoring the UV Index, residents and visitors can make informed decisions about outdoor activities, ensuring safety while enjoying the beautiful Indonesian sun.
As the sun rises, the UV Index gradually climbs, beginning at a mild 1 at 7:00 AM. By 8:00 AM, it reaches 2, indicating an increase in exposure, but it’s from 9:00 AM that the intensity truly ramps up, hitting a moderate 4. The peak occurs at 12:00 PM, where the index soars to an impressive 10, signaling a high risk of harm from unprotected sun exposure. Following this peak, the UV Index begins to gently descend, dropping to 9 at 1:00 PM and then gradually tapering off to 5 by 3:00 PM. As the afternoon wanes, the values decrease steadily, leaving a comfortable 1 by 5:00 PM, and finally settling at 0 by 7:00 PM. It’s a clear reminder that while the midday sun can be mighty, the late afternoon offers a more forgiving vibe for outdoor activities.
