Eastern Mongolia

It’s often hard to understand which region to visit in Mongolia, and when. It’s even harder to decide what to do, and how to plan the best itinerary, when you do finally go! Below find detailed information on the eastern region (Khentii, Sukhbaatar, and Dornod), as well as day-to-day itineraries and other important things to know.

Eastern Mongolia is the road less traveled, and that is precisely its appeal. This is the Mongolia of Chinggis Khaan. Vast open steppe, rolling grasslands, and a nomadic culture that feels completely untouched by tourism. You can ride horses for days without crossing a paved road or seeing another foreign traveler.

It’s not the easiest region to navigate independently, but with the right guide it is deeply, quietly extraordinary. If you want to experience Mongolia as it has existed for centuries, come east.

Seasonal Temperatures & When to Visit

Eastern Mongolia’s climate is a different beast from the other regions. Instead of mountain cold, you get open steppe continental extreme. That means: big swings, bitter wind-driven winters, and surprisingly hot summers.

In Choibalsan, summers are warm, winters are frigid, dry, and windy, with temperatures across the year typically ranging from −23°C (−10°F) to 28°C (83°F). Extreme cold snaps can push to −33°C (−27°F), while summer heat waves have reached 37°C (100°F).

In Öndörkhaan (Khentii), the open flat plain and river-valley position means winter wind chill can push effective temperatures to −40°C (−40°F).

Winter (Dec – Feb)

January is the coldest month in Choibalsan, with an average high of just 8°F (−13°C) and an average low of −9°F (−23°C). The regional January average temperature overall hovers around −22°C. All three provinces experience similar depths of cold, the open steppe offers no shelter from Siberian winds.

Spring (Mar – May)

By May in Choibalsan, average highs reach 67°F (19°C) and lows 41°F (5°C), but March still averages a high of only 32°F (0°C) with lows at 12°F (−11°C). Spring is the windiest, dustiest season across eastern Mongolia, and a late snowstorm in April is entirely normal.

Summer (June – Aug)

July is the peak in Choibalsan, with an average high of 83°F (28°C) and an average low of 59°F (15°C). This is markedly warmer than the north and west. Baruun-Urt’s warmest month also peaks at around 28°C (83°F), confirming how consistent the steppe climate is across Dornod and Sukhbaatar. Khentii’s mountain influence in the north keeps it a few degrees cooler than the open steppe further east.

Fall (Sept – Nov)

September in Choibalsan still averages a comfortable high of 65°F (18°C), dropping sharply to 26°F (−3°C) by November, with lows going from 41°F (5°C) in September to 9°F (−13°C) in November. October is the transition month, day temperatures can still be pleasant but nights turn firmly below freezing.

Key Things to Know for the Whole Region

All three provinces use Tenger Plaza as the UB departure point, not Dragon Center, which serves the north and west.

Only Choibalsan (Dornod) has flights from UB. If time is short, fly there and do the other provinces by road from the east.

You can link the three provinces together: shared jeeps run between Choibalsan, Öndörkhaan, and Baruun-Urt daily, so you don’t have to backtrack to Ulaanbaatar between them.

Eastern Mongolia’s roads are among the least developed in the country. For anywhere beyond the provincial capitals, a 4WD with a local driver is not optional, it’s essential.
