The article presents the characteristics of the incidence and course and variability of the ice phenomena on selected sections of rivers in Przymorze which are influenced by a high level of human pressure. The study also includes the variability of forms of the ice phenomena occurring on the rivers taking into account the structure and the type of ice, which appeared in various phases of ice cover on rivers. When analyzing the variability of ice phenomena into account a number of factors; among other things, the location section of the river, which conducted the observations, the water flow in the profile of the river, the variability of water temperature in the winter and its impact on the number of days with the phenomena of ice on rivers and variability of air temperature during the winter and cool half of hydrological year, that the main factors conditioning the formation of ice phenomena on rivers. The work also included the course of the atmospheric circulation, which determines the course of the air temperature. To describe these changes, the indicator used the North Atlantic Oscillation.
