January weather forecast
Mongolia

January is widely recognized as the coldest month in Mongolia, with temperatures frequently dropping to extreme lows. In the northern and central regions, including the capital city Ulaanbaatar, temperatures can plummet to -30°C (-22°F). The city is known to be one of the coldest capitals in the world, particularly during January, when the mercury rarely rises above -20°C (-4°F) even during the day.

The southern regions and the Gobi Desert, despite their cold desert climate, do not escape the frigid January weather. Temperatures in these areas also regularly fall below -20°C (-4°F), especially during the night. However, they can experience slightly warmer temperatures than the northern regions during the day, often reaching -10°C (14°F).

In comparison to December, January is marginally colder, reaching the lowest point of the annual temperature cycle. Snowfall, which begins in November or December, continues into January, often leaving a persistent blanket of snow across much of the country. Wind speed can also increase during this month, adding to the harshness of the conditions.

The relative humidity in January is quite low due to the cold air and snow-covered ground, making the air seem drier. Precipitation, in the form of snow, is low compared to the summer months, but the persistent cold temperatures mean that any snowfall stays on the ground for extended periods.

As January transitions into February, temperatures remain largely the same, with only slight increases towards the end of the month. Hence, January stands as the epitome of the Mongolian winter, exemplifying the cold and dry conditions that characterize this season.
