In Bugat, Mongolia, understanding the UV Index is essential for maintaining skin health and preventing sunburn. With the region's BSk climate characterized by dry and sunny conditions, residents and visitors alike face heightened exposure to harmful UV rays, especially during the midday hours when the index peaks significantly. From a moderate level of 4 at 9:00 AM to a striking maximum of 9 around 1:00 PM, being aware of UV levels helps you take preventive measures and enjoy the outdoors safely. Staying informed about the UV Index not only protects your skin but also empowers you to make informed decisions about sun safety throughout the day.
The UV Index throughout the day reaches its peak around 1 PM, soaring to a high of 9. Early morning hours see a gentle rise, starting at 1 by 7 AM and gradually increasing to 4 by 9 AM. As the sun climbs higher, the index ramps up significantly, hitting 8 at 12 PM and declining thereafter. From 1 PM onward, the intensity begins to wane, dropping to 7 at 3 PM, then settling to a comfortable 3 by 5 PM. By evening, the index gently tails off, marking 2 by 6 PM and back to a restful 1 by 7 PM. Stay protected during those peak hours to enjoy the sunshine safely!
