The number of days with snow cover in Felin is characterized by a high year to year differentiation. Worth attention are the heavy snow winters of the 1960's and light snow ones of the first half of the 1970's and the end of 1980's. The average number of snow cover days in Felin is 68. The greatest possibility of its occurrence (78 percent) is determined to be the end of January and the beginning of February. The snow cover is the thickest at the end of February. On the average, the first day with snow cover occurs at the end of November and the last one in the third decade of March. In the analysed period, rare were the cases where the snow cover remained constantly for over 70 days. Based on the circulation typology of Hess-Brezowsky, it was stated that in the most snowy winters in Felin, the long occurrence of the snow cover was the result of the increased frequency of the appearance of the meridional forms of circulation and the sets of high pressure over Middle-Eastern Europe. In turns, during the lightest winters in terms of snow-fall, predominant were the zonal forms of circulation, which was reflected by the higher frequency of the wandering lows over the Baltic Sea
