In Sesayap, Indonesia, understanding the UV Index is crucial for protecting your skin from harmful ultraviolet rays. High UV levels, particularly during midday when values peak at 13, can lead to sunburn and long-term skin health issues if not managed properly. Given Sesayap's tropical Af climate, residents and visitors alike face unique exposure risks, especially between 10 AM and 2 PM when UV levels are most intense. By staying informed about the daily UV Index, you can take proactive steps to enjoy the sun safely while minimizing the risk of skin damage.
As the sun rises, the UV Index starts off low at 1 by 7:00 AM, gradually climbing to a moderate 3 by 8:00 AM. The intensity peaks at 12:00 PM with a striking 13, signaling a high level of UV exposure. As the day progresses, the index then begins its descent, dropping from 12 at 1:00 PM to 9 by 2:00 PM, before tapering off to 6 at 3:00 PM. The evening brings a soothing decline, returning to a safe 1 by 5:00 PM and settling at 0 by 7:00 PM. For optimal protection, it's best to limit sun exposure during the peak hours of 10 AM to 2 PM when UV levels are at their highest.
