Mongolia is known as “the land of blue skies” as it gets an average of 260 cloudless days a year. The temperature in Mongolia varies dramatically both seasonally and daily.

Most of the country is hot in the summer and very cold in the winter. Winter temperatures average about -22°F (-30°C). Ulaanbaatar has the lowest average temperature of all national capitals in the world.

July through September is when most of the annual precipitation falls. The northern parts of Mongolia receive 20 to 35 centimeters of precipitation while the southern desert receives 10 to 20 if any at all.
 
The best time to visit Mongolia is between May and October when temperatures are higher. Visiting during the winter is not a problem as long as you can handle the cold weather, dust storms, and the increased difficulty in traveling.

July and August are Mongolia's wettest months, but it still may be worth your time to visit because it is also when the Naadam Festival happens.

The best time to visit the Gobi desert is either in June or September because the temperatures won’t be so high. Be cautious when visiting the desert in the spring because of high winds and dust storms.

Cultural Crossroads Tours of Mongolia at a Glance

• Mongolia: Cultural Landscape and Diversity
  

  Join Cultural Crossroads for a cultural trip to Mongolia, a country with ancient Tibetan-Buddhist traditions, monasteries and friendly spiritual people. Meet lamas, hear the low tones of the horns used to call the lamas to the temple and observe their daily rituals. Our travelers have special access to the Arts Council of Mongolia and its art collection. Meet local artists and crafts people. Enjoy the Hustain Nuruu National Reserve, home to the last remaining species of wild horse, the Takhi. Learn about current conservation efforts and the status of the herds found within the reserve. We will see the Kharakhorum, site of the 13th-century capital of the Mongol Empire of Chinggis Khan. Take in the remote and stunning wilderness of Mongolia when we stay in South Gobi, home to Bactrian camels, Argali mountain sheep, goitered gazelle, golden eagles, saker falcons, jerboas (similar to kangaroo rats) and many endemic reptiles. The Gobi is also home to some of the Northern Hemisphere’s rarest and most elusive mammals such as the dhole, snow leopard, wild camel, and Gobi bear. Cultural Crossroads travelers will stay at the Three Camel Lodge in gers (Mongolian tents), an eco-lodge located near the Gurvansaikhan Gobi National Park. Our trip ends with a visit to a nomadic family leading a local movement to protect and preserve the Bactrian camel populations
