The aim of the study was to determine the relations between parameters of daily cycle of dew and relative air humidity in the seasons and weather classes. The measurements of dewfall were conducted in Białowieża meteorological station (φ = 52°42’ N, λ = 23 °51’ E, h = 163,5 m above sea level). There is moderate correlation between term of maximum dewfall and term of minimum air temperature. The ccorrelation coefficients range front 0,5482 (May) to 0,7114 (September p < 0,001). The highest correlation between term of maximum dew and term of minimum air temperature characterized overcast weather classes during night (5a, 6). The value of correlation coefficient between daily sum dew and time of dewfall occurrence is highest in cloudy days with rain and cloudless nights (class 4b). It was found high and statistic significance (r = 0,8563) dependence of the time dewfall on the time of saturation state. These relationships were greatest in September and October. The influence of time of saturation state on the daily dewfall is greatest in September and October and during cloudy weather by day and small cloudiness by night (class 4b).
