Summary:The characteristics of a polynya, a water opening in the ice field, that is attributed to a single inlet - the navigable Strait of Baltiysk of the Vistula Lagoon of the Baltic Sea - were studied by using satellite images received in 2011-2017. The polynya's average transversal and longitudinal dimensions were about 3 and 4 km respectively. Its area varied from 0.3 to 38 km 2 with an average of 11 km 2 . The polynya area, in general, responded to a tendency of the 5-day average air temperature to increase or decrease and not to its more short-term variations. It was supposed that the marine water inflow in the lagoon determined the existence of the inlet polynya, but not a change of its size during the ice season. The polynya dynamics reflected the multiplicative effect of air temperature, marine water inflow and wind, and probably the surface waves coming from the sea through the lagoon inlet.
