Sea level, which has been rising over the years, constitutes a higher reference level forstorm surges and fl oods. According to the IPCC, extreme phenomena occurred more frequently and thiscould be connected with global climate change. The work presents the relative changes of sea level anda determination of its quantitative and qualitative variability in the eastern part of the coast along thePolish Baltic Sea which was investigated for the purpose of this paper. The analysis is based upon theresults of four tide-gauges: Władysławowo, Hel, Gdynia and Gdansk–Harbour. The fi rst part of the paperexamines long-term and seasonal fl uctuations of sea level, then the paper discusses the matter of amplitudes,and the fi nal part analyses the appearance of high water levels and storm surges during the year.
