April is low for Ulaanbaatar.
April brings real warmth to the afternoons, with highs around 8°C, though nights still drop below freezing. The smog of winter is gone, which makes the city far more breathable.
The catch is that April is the windiest and dustiest month of the year. Strong winds sweep dust and sand off the Gobi into the city and across the steppe, sometimes for days at a stretch. It can be gritty, hazy, and unpredictable — not the postcard Mongolia of green grassland.

Ulaanbaatar in April — Full Picture
April brings real warmth to the afternoons, with highs around 8°C, though nights still drop below freezing. The smog of winter is gone, which makes the city far more breathable.
The catch is that April is the windiest and dustiest month of the year. Strong winds sweep dust and sand off the Gobi into the city and across the steppe, sometimes for days at a stretch. It can be gritty, hazy, and unpredictable — not the postcard Mongolia of green grassland.
Ger camps in places like Terelj begin reopening through April, and the steppe slowly greens toward month's end. It's an acceptable shoulder-season window with low prices, but May and especially June onward are markedly better for the countryside experience that defines a Mongolia trip.
What to Wear & What to Pack
Spring with wide swings — mild days near 8°C, cold nights below freezing. Layers are key: light down or fleece you can shed midday. April is windy with frequent dust storms, so a windproof jacket, sunglasses, and a buff or scarf for the face are useful.
