Understanding the UV Index is crucial for residents and visitors of Lempokasi, Indonesia, a region characterized by its tropical Af climate. With UV levels peaking significantly in the late morning through early afternoon, being aware of these fluctuations is essential for preventing sunburn and promoting long-term skin health. During the height of sun exposure, especially when the UV Index reaches as high as 12 around noon, the risk of harmful effects increases dramatically. By staying informed about the UV Index, you can take proactive measures to enjoy the sun safely while protecting your skin from its potential dangers.
At dawn, the UV Index starts off low at 1 at 07:00, but as the sun rises, so does the intensity of UV radiation. By 09:00, it reaches 5, climbing rapidly to a peak of 12 at 12:00. The midday sun is fierce, with the UV Index hitting its maximum of 11 at 11:00 and slightly dropping to 8 by 14:00. As the afternoon progresses, the index declines steadily, returning to a more moderate 5 at 15:00, then tapering off to 2 by 16:00. The day concludes with a safe 1 at 17:00 and fades to 0 from 18:00 onwards, indicating a reprieve from UV exposure. Remember to protect your skin during those peak hours!
