The country's climate is influenced chiefly by the mountains, Kyrgyzstan's position near the middle of the Eurasian landmass, and the absence of any body of water large enough to influence weather patterns. Those factors create a distinctly continental climate that has significant local variations. Although the mountains tend to collect clouds and block sunlight (reducing some narrow valleys at certain times of year to no more than three or four hours of sunlight per day), the country is generally sunny, receiving as much as 2,900 hours of sunlight per year in some areas. The same conditions also affect temperatures, which can vary significantly from place to place. In January the warmest average temperature (-4°C) occurs around the southern city of Osh, and around Ysyk-Köl. The latter, which has a volume of 1,738 cubic kilometers, does not freeze in winter. Indeed, its name means "hot lake" in Kyrgyz. The coldest temperatures are in mountain valleys. There, readings can fall to -30°C or lower; the record is -53.6°C. The average temperature for July similarly varies from 27°C in the Fergana Valley, where the record high is 44°C, to a low of -10°C on the highest mountain peaks. Precipitation varies from 2,000 millimeters per year in the mountains above the Fergana Valley to less than 100 millimeters per year on the west bank of Ysyk-Köl.
