The most part of the year is quite dry and hot. The daylight in summer is 15 hours and in winter it is no less than 9 hours. The annual average sunlight is 2,500-3,000 hours in the north, and 2,800-3,130 hours - in the south. For comparison, the same amount of sunlight share is typical for California, US. The winters are rather cold and summers are quite hot in Uzbekistan. The coldest month is January. The temperature goes down to 25 and 30 degrees Celsius below zero in the south, and it could be much colder in the northwest of the country - 35 and 38 degrees Celsius below zero. However, there are enough warm days throughout the country in wintertime.
Heavy and long-lying snowfall is not usual for the country. The average snowfall is 5-15 cm, and in foothills - it ranges from 10 to 12 cm.
In southern provinces of the country, the spring usually arrives in February, but it reaches the Aral Sea region only in April. In spring, the weather is very variable; the warm days may be followed by chilly and cold days.
In the south, the summer starts somewhere in May, and it usually lasts from four to five months. The hottest month is July when the temperature reaches 42-47 degrees Celsius. In mountainous areas the summer temperature is about 22-30 degrees Celsius. In summer the ground surface temperature could go up to 60 degrees Celsius, and in desert areas - up to 70 degrees Celsius.
The rainfall distribution is quite different. On the plains the annual rainfall is on average 100-200 mm and in mountains it reaches 900 mm. Most of the precipitation falls in spring and winter periods. From one to six percent out of the total annual precipitation falls during summer and from 10 to 20 percent -in autumn.
