Uzbekistan has an arid, continental climate characterized by cold winters, hot summers and limited precipitation across most of the country. The primary climactic features are aridness, abundance of heat and sunlight, and sharp day-night and winter-summer temperature variations. Summer in Uzbekistan is long, dry and hot, spring is humid and winter is irregular. Rainfall is highly varied depending upon area of the country and seasonal variation patterns. Increases in rainfall are expected to continue in the country’s piedmont zone, while decreases are expected in the country’s highland areas. Uzbekistan is at risk for an increase in temperature and increasingly variable precipitation patterns.
- Mean summer temperatures (May to September) range from less than 22°C to 28-30°C in central districts.
- Mean winter (December to early February) temperatures range from -9°С in northern districts of the country to 5-7°C in south-eastern districts.
- Extreme temperatures have dropped below -35°С during severe winters and have exceeded 50°С in summer heat extremes.
- Since 1938, all regions of Uzbekistan have experienced a trend of increased mean minimum and maximum temperatures for all seasons of the year. This warming trend is less pronounced in the Tyan-Shan and Pamir-Alay Mountain branches than in the rest of the country.
- Precipitation falls predominately in winter and spring, and rainfall is extremely sparse between June to August.
- March and April typically have the highest rainfall.
- Changes in historical precipitation patterns have resulted in increased aridity in agricultural areas, low river flow and over-stressed water sources.
