Mongolia's extreme continental climate features long, freezing winters and short summers, when most precipitation falls. The country receives an average of 257 cloudless days a year.
Rainfall is highest in the north, which averages between 20 and 35 centimetres per year, and lowest in the south, which receives 10 to 20 centimetres. Most years, some parts of the Gobi region in the far south don't receive any precipitation at all.
Eastern Mongolia's climate and landscape have more in common with northeastern China than Central Asia. Winds are less violet and temperatures are less severe than in western Mongolia, where winter daytime temperatures drop to -4ºF (-20ºC).
The high season runs from June to August, when conditions are mostly warm and dry, with some thunderstorms. May and September account for the shoulder seasons, when the weather can be changeable. Winds, dust storms and frigid temperatures characterise the low season, which lasts from October to April.
