Understanding the UV Index in Lobuche, Nepal, is essential for safeguarding your skin health in this high-altitude region. With its unique ET climate, Lobuche experiences significant UV exposure, particularly during peak hours when indices can soar to 20 and above. Awareness of UV levels is crucial for preventing sunburn and other related skin issues, as even brief sun exposure can pose risks. By staying informed about the UV Index, you can take proactive measures to protect yourself against harmful rays and enjoy your adventures in this stunning part of the Himalayas.
At sunrise, the UV index starts at a moderate 5 at 7:00 AM, but as the sun rises higher in the sky, it quickly escalates. By 8:00 AM, it reaches a notable 10, signaling increased exposure risks. The peak intensity occurs at 11:00 AM, with the index soaring to 22, indicating very high levels of UV radiation. Throughout the midday, it remains dangerously elevated, hovering around 20 through 10:00 AM and 21 by 12:00 PM. As the afternoon progresses, the UV index begins to decline, dropping to 17 at 1:00 PM and then steadily decreasing to 12 at 2:00 PM. By 3:00 PM, it's a more manageable 7, and as evening approaches, the levels fall sharply to 3 at 4:00 PM, then to 1 by 5:00 PM and onward into the night, where it reaches 0 by 7:00 PM. This data underscores the importance of sun protection during those peak hours when the UV index is at its highest, especially between 10:00 AM and 2:00 PM.
