Understanding the UV Index in Tanjungampalu, Indonesia, is crucial for safeguarding your skin and overall health. With the region’s tropical climate, the sun's rays can be intense, especially around midday when the UV Index peaks at a striking 13. Awareness of these UV levels can help you take proactive measures to prevent sunburn and reduce the risk of long-term skin damage. By paying attention to the hourly fluctuations in UV exposure—from a low of 1 at sunrise to a dangerously high 11 during the peak hours—you can enjoy the beautiful beaches and vibrant outdoors while keeping your skin safe.
As the sun rises, the UV Index begins its gradual ascent, hitting a mild 1 by 7:00 AM. The intensity grows steadily, reaching 2 by 8:00 AM and then surging to 5 at 9:00 AM. By 10:00 AM, the index peaks at a robust 8, warning of increasing exposure risk. 11:00 AM sees the UV rays intensify to an impressive 11, leading to a maximum of 13 at 12:00 PM, making it critical to stay protected. The afternoon sun starts to mellow out, dropping to 12 by 1:00 PM, then gradually tapering off to 10 at 2:00 PM, 6 at 3:00 PM, and further declining to 3 at 4:00 PM. Finally, as evening descends, the index falls to 1 by 5:00 PM and remains at that level through 6:00 PM, until fading to 0 after sunset at 7:00 PM. Stay vigilant and shield yourself during those peak midday hours!

This trend indicates that January through April are high-risk months for UV exposure, necessitating vigilance, especially for outdoor activities, as the burn time is a mere 10 minutes at any time during these months. While the UV Index remains high into the summer months, dropping to 12-14 from June to August, the risk of sunburn remains significant. As fall arrives, UV Index values taper slightly but still pose a risk with figures of 15 in September and October. Visitors and residents are strongly advised to use sunscreen, wear protective clothing, and seek shade during peak sun hours, particularly from January to April, to minimize the risk of skin damage.
