The water level in the Baltic Sea has significantly decreased since the beginning of the year, attributed to high pressure over the region and persistent east winds pushing vast amounts of water into the North Sea. Academician Tarmo Soomere noted that although the current situation is concerning, with the water level being at its lowest in 140 years, this long-term water exchange from the North Sea is expected to replenish the oxygen-rich waters in the Baltic, thus improving its ecosystem.

The drastic change in water levels has been marked by reports from German scientists, indicating unprecedented low levels not seen since 1883. Soomere clarifies that while the current drop may sound alarming, it is part of a natural cycle that could result in a healthier marine environment in the long run. He pointed out that Estonia has not set new records during this episode, as extreme drops usually require specific conditions like minimal ice coverage and stronger winds.

The recent fluctuation was measured with some areas around Väinamere showing a decrease of up to 75 centimeters below the average. Historical records from Estonia signify that the lowest levels were encountered previously in 1959 under similar circumstances, showcasing how these extreme changes can impact the sea's health and marine life.
