Keywords: climate change | annual precipitation in Ljubljana and Zagreb | mean annual Sava flow through Zagreb | atmospheric pressure in Zagreb

Correlation coefficient of 0.81 between Sava River flow through Zagreb and precipitation in Ljubljana points at dominant significance of precipitation. In the warmest months Sava flow is very much dependent on evapotranspiration. Sava River flow has downward trend, and two intervals can be sharply distinguished: 1926-1959 and 1960-1995. That is the result of the identical precipitation trend at the Upper Sava. There is the trend of atmospheric pressure rise in the entire observed period. "Precipitation continentality" is characterized by change of trend. Share of "summer" precipitation has been declining since 1960.
