Архангай
Arvaikheer has a cold semi-arid climate (Köppen climate classification "BSk") with mild summers and relatively mild winters by Mongolian standards. The 30 degrees Celsius difference between average January and average July temperature makes it the mildest place in Mongolia, along with Tsetserleg in Arkhangai Province. It is located in a microclimate in the center of Mongolia which sees less harsh winters than the rest of the country. Its elevation at the foot of the eastern hills of the Khangai Mountains augments its mildness by keeping it distant from cold air pools in low basins. Most precipitation falls in the summer as rain, with some snow in March, April and October. Winters are very dry.
