Mongolia Weather | Mongolia Climate

Mongolia is not coldest and remotest part of the world, as it is often portrayed in the Western media. Though winter last from November to March, the real cold of - 30 Celsius lasts only one month, from mid-December to January. The rest of winter the temperature fluctuates around -10 -14 Celsius. It should be noted that blizzards and dust storms often occur in spring, making the period from the snow melting in late March to the first grass in late May the least comfortable. 

Summer from mid-May to mid-September is usually warm with average temperature of 18 to 26 C. There are short rains in July and early August. On some days temperature may go above 30 C which can be felt hard, especially in the South Gobi region.  Almost 70% of precipitation falls in the summer, but this does not mean rainy days. Rains rarely last for more than 2-3 days. Most of rains occur in mid- July and early August and wise herders prefer to move away from rivers and put up their dwellings on hills to avoid sudden floods. The highest temperatures are in the Gobi Desert region with 30 Celsius lasting for more than 40 days. On some days it can be 40 Celsius.

One specific of the weather visitors to Mongolia should be aware of is the drastic drop in temperature from day to night. It is strongly advisable to carry a sweater or even light jacket towards the evening. It can become especially chilly at night in South Gobi. Winds are a regular feature of Mongolia, with rarely a day without a slow breeze of 4-9 meters per second. In summer, cool winds come mostly from the northwest and west bringing in some relief from the summer heat. However, the collision of warm and cool air masses result in sudden heavy rains.

Global warming has had its effects on Mongolia. Experts say that average annual temperatures have raised by 1-2 Celsius degrees, making winter milder and summers hotter. The air pressure is the lowest in July, falling down to 779- 900 bar as compared to 1041 ml/bar in Ulaanbaatar in winter. The average monthly temperature and precipitation in Ulaanbaatar, the capital of Mongolia, is 20 C (65 f) in summer, and -20 C (-13 f) in winter.
