In February 2026, historically low water levels were recorded in the Baltic Sea, in some places, the lowest in almost 100 years. This was mainly due to a stable high-pressure system and strong easterly winds over Scandinavia, which pushed water out of the Baltic Sea. There was hope that fresh, oxygen-rich and salty water would flow in from the North Sea to the heavily tested inland sea and its oxygen-depleted seabed – but that did not happen.
