The northern part of the Fergana region is occupied by the Karakalpak and Yazyavan steppes, and is bounded on the south by a tributary of the Olay ridge. Fergana region is a high seismic zone. The climate is continental, the winters are mild, sometimes very cold. The average temperature in January is 3.2 C, in July – 28 C. The lowest temperature is 27.9 C. The maximum temperature is 42 C. Strong “Kokand wind” blowing in the west of the valley has a negative impact on the climate. In the south-east it blows summer wind. Annual precipitation ranges from 100 mm in the west (around Kokand) to 170 mm in the east, and up to 270 mm on the mountain slopes, mainly in the spring. Vegetation period is 210–240 days. The Syrdarya River flows along the north-western border of the region. Isfara, Sokh, Shohimardon, Isfayramsay start from the Alay ridge. The rivers are saturated with ice and snow. There are mainly gray soils and meadow-swamp soils, mostly hungry and typical gray soils on the hills, alluvial-meadow soils on the terraces of the Syrdarya, sandy and loamy meadows in the northern part of the region.
