The climate of Barnaul is
continental (according to the Köppen classification, humid continental climate with warm summer - Dfb), with very cold winters, during which the temperature is normally below freezing, and warm summers.
Barnaul is a city of 630,000 inhabitants, the capital of the Altai Krai (Territory), located in southwestern Siberia, at the confluence of the Ob and Barnaulka rivers, at 200 meters (650 feet) above sea level and at 53 degrees north latitude.
Precipitation is not abundant, since it amounts to about 445 millimeters (17.5 inches) per year. In fact, due to the location east of the Urals and not far from the steppe of Central Asia, we are close to an arid area, which includes Kazakhstan, whose border is about 350 km (215 mi) to the southwest.
The rainiest season is summer.
Furthermore, due to the distance from all seas and the absence of obstacles for air masses, the climate is characterized by
temperature swings.
