Understanding the UV Index in Lamjung, Nepal is crucial for protecting your skin and overall health. With the region's Cwb climate—characterized by mild temperatures and distinct seasons—UV exposure can vary significantly throughout the day. Knowledge of UV levels is essential as it helps in preventing sunburn and minimizing long-term skin damage. For instance, peak UV levels in Lamjung can reach a dangerous 15, especially between 11 AM and 1 PM, indicating a high risk of harm from unprotected sun exposure. Being aware of these levels empowers residents and visitors alike to take necessary precautions and enjoy the beautiful outdoors safely.
At sunrise, the UV Index begins at a modest 4 by 7:00 AM, but it quickly surges as the morning unfolds. By 8:00 AM, it reaches 7, and then climbs dramatically to a peak of 15 at both 11:00 AM and 12:00 PM. This intense period of UV radiation calls for caution, as 10:00 AM marks the onset of the 14 index. After the zenith, the values start to taper off, with the index dropping to 9 at 2:00 PM and further declining to 5 by 3:00 PM. As the day winds down, 4:00 PM sees it fall to 3, and by evening, the UV Index dwindles to negligible levels of 1 at both 5:00 PM and 6:00 PM, finally resting at 0 by 7:00 PM. It's essential to stay protected during those peak hours to ensure safe sun exposure!

February marks the transition into very high levels, prompting increased caution as the burn time decreases to just 15 minutes. The months of April through September are particularly critical, characterized by extreme UV exposure of 10 minutes burn time.
