The most characteristic feature that distinguishes the Caspian sea from other large bodies of water is the change in its level in a wide range. According to paleogeographic, archaeological and historical data, over the past 3 thousand years, the amplitude of changes in the level of the Caspian sea was about 15 m.
RSE "Kazhydromet" makes a weekly forecast of the level of the Caspian sea. In the Northern part of the Caspian sea, the level fluctuation is expected around minus 28.29 m with a rise to the maximum level of minus 28.01 m and a decline to the minimum level of minus 29.10 m.
In the Middle part of the Caspian sea, the sea level fluctuation is expected around minus 28.34 m with a rise to the maximum level of minus 28.03 m and a decline to the minimum level of minus 28.80 m.
The actual state of the water surface of the Caspian sea for the period from 19 to 24 December 2020 corresponds to the previous weekly forecast.
