The climate varies regionally. The low-lying Fergana Valley in the southwest is subtropical and extremely hot in summer, with temperatures reaching 40 °C (104 °F) The northern foothills are temperate and the Tian Shan varies from dry continental to polar climate, depending on elevation. In the coldest areas temperatures are sub-zero for around 40 days in winter, and even some desert areas experience constant snowfall in this period. In the lowlands the temperature ranges from around −6 °C (21 °F) in January to 24 °C (75 °F) in July.
Climate change in Kyrgyzstan is already having impacts Among the countries in Eastern Europe and Central Asia, Kyrgyzstan is the third most vulnerable to the effects of climate change, such as changes in weather patterns that could lead to prolonged periods of precipitation and drought. Their average temperature has increased from 5.8 °C to 6 °C so far within the last 20 years. By 2060, there is an expectation of a 0.2 °C increase in average mean temperature, as well as a 0.3 °C increase by 2100. However the very slight increase in temperature is expected to positively affect climate-sensitive sectors such as agriculture, energy, and forestry as more land is within the optimum temperature band.
