The weather in Mongolia

The climate in Mongolia is unstable, so it has a long cold and dry winter and short summer.

Spring: Spring months in Mongolia are March, April and May. There are many windy days through spring and weather so the weather can change. You might meet all 4 seasons on the same day, like nice sunny warm in the morning and then suddenly it turns to windy and then it might snow or rain.  You’d never predict the weather during spring in Mongolia. The average temperature in March will be 0 +10 degrees Celsius, in April +5 +15 degrees Celsius, in May +10 degrees Celsius in the Southern and eastern part of the country (Gobi and steppe), and it’ll be slightly cooler in the Central and Northern of Mongolia. Sometimes the temperature will drop down below zero during the night in central or Northern Mongolia.

Summer: Summer months in Mongolia are June, July and August.  Summer in Mongolia is pretty comfortable to travel around due to sunny warm weather with blue sky, green steppe covered with livestock. The average temperature is +20+ 30 degrees Celsius. Sometimes it gets hotter, it might get up to +35 to 40 degrees Celsius specially, in the Gobi region.  But there is always breeze, usually at night.  There are short rains in summer. In the evening, it’ll usually be chilly in the central and northern regions of Mongolia even though it’s summer. During your trek you might cross paths with a thunderstorm specially after days of very hot weather.

Fall: Fall months are September, October and November.  September is really colorful and it’s a great month to travel around because it won’t be too hot and not so cold either. Average temperature will be around +10+20 degrees Celsius during the day and +5+15 degrees Celsius during the night.  In October, snowy weather starts and temperatures will drop below zero degrees. But you’ll meet many sunny days specially in the Gobi Desert.  In October, average temperature will be -5+5 degrees Celsius during the day and from -10 to 0 degrees Celsius during the night.
