Understanding the UV Index in Tsenher, Mongolia, is essential for safeguarding your skin and overall health. With the region's high-altitude climate characterized by cool temperatures and significant solar radiation, awareness of UV levels is crucial for preventing sunburn and reducing the risk of long-term skin damage.

By staying informed about the UV Index, residents and visitors can take necessary precautions to enjoy the beautiful Mongolian outdoors safely.
At dawn, the sun casts its softest rays, with the UV Index peaking at a mild 1 at 07:00. As the morning progresses, the intensity gradually builds, reaching 3 by 08:00 and climbing to 4 by 09:00. The day's heat peaks during late morning and early afternoon, with a striking 10 at 12:00 and 13:00, indicating a strong need for protection against harmful UV rays.
