Understanding the UV Index is crucial for everyone in Hovsgol, Mongolia, where sun exposure can vary significantly throughout the day. As a region characterized by a BWk climate, Hovsgol experiences stark sunlight, especially between 11:00 AM and 2:00 PM, when UV levels can reach a peak of 10—indicating very high risk for harm from unprotected sun exposure. Being aware of the UV Index not only helps in preventing sunburn but also plays a vital role in maintaining long-term skin health. With the right information, residents and visitors can take proactive steps to enjoy the beautiful Mongolian outdoors safely!
The UV Index for the day reveals a dramatic increase in solar intensity as the morning progresses. Starting at a mild 1 at 07:00, the index reaches a moderate 3 by 08:00. However, from 09:00 onward, the sun's rays become increasingly potent, hitting 5 at 09:00, peaking at a striking 10 between 12:00 and 14:00. This indicates there’s a high risk of harm from unprotected sun exposure. As the afternoon fades into the evening, the index declines steadily, dropping to 8 at 15:00 and tapering off to 1 by 19:00. Stay protected during those peak hours when the sun shines brightest!
