Temperature observations show increasing trend of maximum and minimum absolute temperature in between 1961 and 2022, reflecting a global warming. Number of hot days is increasing, including the frequency of extreme hot days with daily maximum temperature above 35 °C. In the summer of 2013, the highest temperature so far was measured in Slovenia, and local temperature records were observed at many meteorological stations. A record number of hot days was observed in 2022. Number of days with temperature below zero show a decline.

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 1961-2022.

Environmental protection is important to the residents of the EU and Slovenia. The most significant environmental issues mentioned are growing amount of waste, air pollution, and climate change. A large majority of respondents agreed with statements expressing concern about various environmental problems and acknowledging their impact on their daily lives and health.

Trends in annual precipitation are not as obvious as temperature trends. Changes between years and differences between regions are significant. According to climate change projections, annual precipitation will slightly increase while changes in seasonal precipitation will be noticeable. The most worrying are summer conditions, because less precipitation and higher temperature might result in higher frequency of droughts. In winter, more precipitation may lead to an increase in flooding events.

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