In Lasehao, Indonesia, awareness of the UV Index is crucial for protecting your skin from harmful ultraviolet rays. With peak UV levels soaring as high as 12 around midday, understanding these readings is essential for effective sunburn prevention and maintaining overall skin health. The town's tropical climate leads to increased UV exposure, especially during the sun's zenith. By keeping an eye on the UV Index, residents and visitors alike can enjoy the beautiful outdoors while ensuring their safety under the sun.
At dawn, the UV Index starts with a gentle 1 at 7:00 AM, gradually rising to a moderate 3 by 8:00 AM. As the sun climbs higher, the index surges, reaching a peak of 12 at both 11:00 AM and 12:00 PM, indicating a strong need for sun protection during these hours. The intensity wanes in the afternoon, dropping to 8 at 2:00 PM, followed by a steady decline to 5 at 3:00 PM, and further down to 2 by 4:00 PM. As the day concludes, the UV exposure lessens drastically, with values retreating to 1 by 5:00 PM and ultimately dropping to 0 from 6:00 PM onward. This hourly data underscores the importance of midday sun safety practices, as the risk for skin damage is significantly heightened during the peak hours.
