The climate of Yakutia is sharply continental: the amplitude of temperature fluctuations is 100°C (from 40°C in summer, to –60°C in winter). The average air temperature in January is –43.2°C, in July - 18.7°C.
The Pole of Cold is situated in the Oimyakon region, where was fixed a temperature –71.2°C. Winter in Yakutia is long, cold and little snowy. Summer is short, droughty with high temperature in greater part.
The duration of the frost-free season in Yakutia varies. For the most part, it depends on the latitude, the above sea level, and the character of the earth surface. The longest warm season is observed in the valley of the middle reaches of the river Lena, it is 90-100 days long (Yakutsk – 96 days, Olekminsk – 100 days). It is 1 to 2 months long on the coast. And it is only 10-15 days long on the Novosibirski islands.
The amount of precipitation in Yakutia is very low, the anticyclone weather conditions and the dryness of incoming air masses accounts for this. Annual precipitation comes to 290 mm on the whole territory of Yakutia . The distribution of precipitation during the year is uneven, most of it falls during the warm season of the year. The decrease in precipitation from the south to the north, and from the southwest to the northeast has been observed. The central part of Yakutia annually receives about 200 mm of precipitation (Yakutsk receives 202 mm, which is three times less then Moscow).
Thus, the climatic features of Yakutia are defined by its geographical location in the northeast of Asia, the emergence of a powerful Siberian anticyclone in the winter, the free flow of the arctic air masses, the distance from the Atlantic ocean, difficult to access warm and moist air masses from the east and the south, as well as the complex landform.
