October is low for Ulaanbaatar.
October marks the slide back into winter. Daytime highs drop to around 7°C and nights fall below freezing, with the first snows possible and the steppe fading to brown. Most ger camps have closed for the season, so the signature countryside ger stay is largely off the table by mid-month.
It's still a feasible time for city sightseeing — the Genghis Khan Statue, Gandan Monastery, museums — and prices and crowds are low. But as the cold deepens, homes start burning coal again, and Ulaanbaatar's notorious winter smog begins creeping back, particularly in the second half of the month.

Ulaanbaatar in October — Full Picture
October marks the slide back into winter. Daytime highs drop to around 7°C and nights fall below freezing, with the first snows possible and the steppe fading to brown. Most ger camps have closed for the season, so the signature countryside ger stay is largely off the table by mid-month.
It's still a feasible time for city sightseeing — the Genghis Khan Statue, Gandan Monastery, museums — and prices and crowds are low. But as the cold deepens, homes start burning coal again, and Ulaanbaatar's notorious winter smog begins creeping back, particularly in the second half of the month.
Early October can still offer crisp, clear days and late autumn color, but overall this is a fast-closing shoulder season. Unless you specifically want a quiet, cheap city visit, the better countryside months are behind you and the smoggy cold months ahead.
What to Wear & What to Pack
Cold autumn turning to winter — highs near 7°C, nights below freezing. Warm down jacket, layers, hat and gloves for the cold mornings and evenings. As heating ramps up late in the month, the city's smog begins to return; consider a mask for late October.
