In Hongor, Mongolia, being aware of the UV Index is crucial for maintaining skin health and preventing sunburn. With the region's semi-arid climate (BSk), residents and visitors often face heightened exposure to harmful UV rays, particularly during the peak hours of the day. Understanding the varying UV levels—from a moderate 2 in the early morning to a staggering 10 around noon—empowers individuals to take necessary precautions against skin damage.
