    Spring dust storms

    15 Mar – 31 May · usuallyDust season

    Gobi dust rides the spring wind up over the city several times a season, turning the sky orange and grounding domestic flights. It is a different problem from the winter coal smoke and it hits harder outdoors. Source ↗

Ulaanbaatar (Ulan Bator) weather in June

Busy — school holidays in 3 of the markets that fill it, one of its best months for weather

  • Season

    Steppe season

    1 Jun – 15 Sep · usuallyDry seasonBook early

    The countryside ger camps, the domestic flights to the west and most of the dirt roads out of the capital only work in these months. Outside them the touring season is effectively shut, whatever the city itself is doing.

  • Nature

    Steppe in flower

    10 Jun – 20 Jul · usuallyWildflowers & blooms

    The grassland turns green and flowers within weeks of the first summer rain, edelweiss and iris across the valleys around Terelj. It is the short window the countryside actually looks the way the posters do.

July in Ulaanbaatar (Ulan Bator)

Busy — Naadam, school holidays in 5 of the markets that fill it

  • Season

    Summer rains and soft roads

    1 Jul – 25 Aug · usuallyMonsoonRisk

    Most of the year's rain falls in these weeks as heavy afternoon showers, and the dirt tracks out to the ger camps turn to mud and river crossings rise. Drivers plan detours rather than schedules.

  • Festival

    Wrestling, archery and horse racing over three days, opening with a flag ceremony and a stadium parade on the eleventh. The city runs on holiday hours and beds have been booked since spring. Source ↗

Shoulder season — school holidays in 3 of the markets that fill it, an ordinary month

  • Season

    Clear autumn weeks

    1 Sep – 15 Oct · usuallyDry season

    The short stretch after the summer rains and before the heating plants fire up: dry, clear, the steppe gone gold, and the air still clean. Camps start closing through September, so book ahead rather than turn up.

  • Nature

    Larch turning in Terelj

    10 Sep – 5 Oct · usuallyAutumn colour

    The Siberian larch on the hills east of the city goes gold for a fortnight before it drops, and the first hard frost usually ends it. The camps stay open a few weeks past it.

Still on: Steppe season (1 Jun – 15 Sep (usually))

Shoulder season — an ordinary month

  • Hazard

    Winter smog

    1 Nov – 31 MarSmoke season

    Raw coal burned in the ger districts for heating, held down over the valley by an inversion, makes this one of the worst urban airs anywhere between November and March. It is the single strongest argument against a winter trip. Source ↗

Quiet — school holidays in 5 of the markets that fill it, one of its worst months for weather

  • Hazard

    Deep winter and dzud

    1 Dec – 28 Feb · usuallyExtreme coldClosures

    The coldest capital on earth in the coldest weeks of its year, and the season when a dzud can strand herders and close the intercity roads. City sightseeing works; anything beyond the ring road needs a plan B. Source ↗
