Weather in Mongolia — What to Expect & How to Prepare

Mongolia truly is the land of the blue sky — and for good reason. With vast open landscapes and relatively low humidity, the skies here are clear more often than not. But because of its continental climate, Mongolia also experiences dramatic seasonal changes and daily temperature swings, especially in the Altai Mountains and other high‑altitude areas. 

Understanding the weather will help you pack wisely and plan your adventure with confidence.

🌤️ Four Distinct Seasons

Mongolia has four well‑defined seasons, each offering a unique travel experience: 

🌿 Spring (March–May)

Early spring can still be chilly, especially in mountain valleys.

May brings warmer days and blooming landscapes — ideal for cultural tours and early trekking.

☀️ Summer (June–August)

Summer is the most popular time to visit.

Daytime temperatures can reach +20 °C to +25 °C (68–77 °F) in many regions, but nights stay cooler.

Occasional summer rainstorms add fresh beauty to the scenery.

🍁 Autumn (September–November)

Crisp air and golden pastures make fall spectacular for photography and horse treks.

Early mornings can be cold — perfect for layering warm clothing.

❄️ Winter (December–February)

Winter is cold and dry, with temperatures often well below freezing.

Despite the chill, blue skies dominate, and winter landscapes are starkly beautiful.

📍 Temperature Guide (City & Mountain)

🌦️ Daily Weather Variability

Even within a single day, Mongolia’s weather can change quickly — sunny mornings may give way to afternoon showers or brisk mountain winds. That’s why layered clothing and versatile gear are essential for travelers. 

☀️ Sun & UV Exposure

Because Mongolia’s skies are often clear, UV exposure can be high even on cool days. Be sure to bring:

• Sunglasses
• Sunscreen with good SPF
• A wide‑brimmed hat for daytime excursions

🏕️ What This Means for Your Adventure

Trekking & Mountain Tours: Prepare for cooler mountain weather and sudden changes — layers and waterproof gear are musts.

Cultural Tours & Festivals: Spring, summer, and early autumn offer the most comfortable weather for exploring nomadic life.

Photography & Wildlife: Clear skies with dramatic lighting make Mongolia perfect for photography almost year‑round.
