Climate and Weather in Ulaanbaatar, Mongolia

The climate of Ulaanbaatar

What is the capital of Mongolia? The city of Ulaanbaatar (also written as Oelan-Bator or Ulan Bator) is located in the valley of the Tuul River, about 1,350 meters above sea level. Ulaanbaatar has a cold steppe climate (type BSk according to the Köppen climate system). With an average daily temperature of -2.4 degrees Celsius on an annual basis, Ulaanbaatar is the coldest capital in the world. The city owes this to its isolated location in a valley, at the foot of the mountain Bogd Khan Uul. Due to an almost permanently present high-pressure system, the winter lasts a long time and is cold to very cold. The average daily temperature in January and February is around or just below minus twenty degrees, while the mercury can drop to as much as minus forty degrees on some nights. After a short spring, in which sandstorms can occur, temperatures rise rapidly to well above twenty degrees during the day and about ten degrees when it is dark. There are regularly outliers to thirty degrees or more. The summer months are also the wettest months, although this period can still not be called wet in absolute terms, with a maximum of 60-65 millimeters of rain in a month. See abbreviations for Ulaanbaatar.
