Check the live forecast above before travel, as Mongolia’s weather is defined by extreme seasonal swings: bitterly cold, dry winters and short, warm summers. Its continental climate means temperatures can drop below -30°C in January and climb above 25°C in July, with most rain falling between June and August.
What is the weather in Mongolia like year round?
Mongolia has a harsh continental climate with four distinct seasons. Winter (November to February) is long, dry and extremely cold, with frequent clear skies and occasional blizzards. Spring (March to May) is windy and dusty, often bringing sudden cold snaps. Summer (June to August) is short but warm, with the majority of annual rainfall. Autumn (September to October) is cool and mostly dry, offering stable conditions before winter sets in.
What is the best time to visit Mongolia?
For travellers, summer (June to August) is the most practical season. Daytime temperatures range from 20°C to 30°C, making outdoor activities like hiking and the Naadam Festival comfortable. However, be prepared for sudden afternoon showers. For those seeking winter experiences, December to February offers unique opportunities like the Ice Festival, but you must pack serious cold-weather gear (temperatures often stay below -20°C).
What is Mongolia’s weather like in winter?
Winter runs from November to February. Daytime highs in Ulaanbaatar average -16°C in January, with nights frequently dropping below -30°C. The air is very dry, and snow is light but persistent. Strong winds can create dangerous wind chills.
Does it rain much in Mongolia?
No, Mongolia is generally dry. Most of the country receives less than 250mm of rain annually. The bulk falls as brief, heavy showers during July and August. The Gobi Desert in the south receives even less, often under 100mm per year.
How does Mongolia’s weather compare to Australia?
Mongolia’s continental climate is vastly different from Australia’s coastal weather. While Australian summers are hot and humid in the north, Mongolia’s summers are short and mild. The biggest contrast is winter: Mongolia’s extreme cold is comparable to a severe Tasmanian winter, but much drier.
