In January an average temperature ranges between -4 °C and -9 °C while in July it is from + 20 °C up to +27 °C in low mountainous regions and the Issyk-Kul. Absolute low temperatures of air drop in winter down -50°C on the Ak-Sai. Absolute high temperatures of air reach +43°C - +44°C in Chu Valley and in the South of Kyrgyzstan. An average wind velocity is small, 1-3m/sec, however the mountain landscape and availability of a large area of water of the Issyk-Kul cause numerous winds. Frequently alongside with alteration of day and night the wind direction also changes. Intrusion of cold air into the Issyk-Kul hollow is accompanied with a stormy wind the velocity of which sometimes mounted to 40km/h. In the valley areas of Kyrgyzstan a total amount of precipitation makes up 230-500 mm. In the mountainous areas it can reach 1500 mm. In warm seasons precipitation falls more than in a cold ones. The most cloudy sky can be observed in the end of winter and in the beginning of spring. A thunder storm is a frequent phenomenon. The largest number of thunder storms fall in June and July.
