The length of the annual growing season is increasing almost everywhere in Europe, mostly in Eastern and Northern part, and less in Western Europe, the Mediterranean and in southern Europe. In Slovenia, the length of the annual growing season is increasing, especially since the mid-1990s. According to projections, the duration of the annual growing season throughout Europe will increase in the future.

Precipitation is highly variable in space and time, even more than temperature (storms and hail). In the last two decades, Slovenia is observing catastrophic droughts and abundant precipitation resulting in floods, sometimes drought and floods occur even within the same year. The maximum snow cover depth and the depth of fresh snow decreased in the period 1961-2011.
