The climate of Azerbaijan is very diverse and transitional from temperate to subtropical. The climate of Azerbaijan is mainly influenced by geographic location, topography and the Caspian Sea. Within the country, several types of climate are distinguished, from dry and humid subtropical (Lankaran) to mountain tundra (high mountains of the Greater Caucasus). Due to the strong influence of altitudinal zonation, the territory of the country is quite heterogeneous in weather conditions (there are 9 climatic zones in total). The average July temperature ranges from -1 ° C in the highlands to +28 ° C in the lowlands, in January, respectively, from -22 ° C and +5 ° C.Precipitation falls from 200 mm. per year on Absheron (including Baku), up to 1200 - 1700 mm. on the Lankaran lowland. Strong north winds are characteristic, mainly in the fall.
In the Republic of Azerbaijan, the regime of air temperature and its distribution over the territory is logical and is formed depending on the characteristics of the air flows entering the country, the relief of the territory and the proximity of the Caspian Sea to certain areas. Along the coastal territories to the Caspian Sea (approximately 20 km from the sea), the air temperature drops slightly in summer, and in contrast, rises in winter. At the same time, to a certain extent, the temperature softens the influence of hot and dry air flows coming from Central Asia. The average annual air temperature in the Kura-Araz lowland, in the coastal zone in the south of the Absheron peninsula, including in the Lankaran lowland, reaches 14 - 15 ° С. Toward the mountains, the air temperature decreases, and at elevations of 2000 meters it is 1 - 4 ° С, 3000 meters - -5 - -3 ° С
