Mongolia Weather

Although it boasts over 260 sunny days a year and is known as the 'Land of Blue Sky', Mongolia has an extreme continental climate with temperatures that have been known to range over 37°C (99°F) in one day. Only in summer does cloud cover shield the sky. Humidity is usually zilch and sunshine is intense. Gobi summer temperatures hit 40°C (104°F) but winter winds often send the mercury plummeting to -30°C (-22°F) or lower. You can see snow in the Gobi Desert as late as April and some lakes remain frozen until June. There's a short rainy season from mid-July to September, but showers tend to be brief and gentle. Because of the high altitude, evenings are cool even in summer.

Ulaanbaatar is possibly the coldest capital city in the world. Temperatures generally start to drop below 0°C (32°F) in October, sink to -30°C (-22°F) in January and February and remain below freezing until April. Horrific dust storms kick up during the short spring (May to June). July to September is pleasant, but it can still suddenly turn cold, and unfortunately, most of the city's rain falls in this period. Summer daylight lasts until 22:00.
