Abstract: In this article are presented trends of temperature, precipitation, water balance and some other climatic phenomena in Slovenia and their their influence on agricultural production. Analysed are the changes of monthly, seasonal and annual averages in observational sequences. Treated is also dynamics of trend changes in the observational period. In Slovenia temperature growth, water balance decrease, decreasing number of snowing days and, consequently, also decreasing number of days with snow cover are being registered in the last couple of decades. The consequence of the changing of climate elements regime and increasing number of extreme climate circumstances, having either direct or indirect influence on agriculture. Water balance in Ljubljana decreased with the dynamics of 261,32 mm/100 years and in Maribor with the dynamics of 240,45 mm/100 years. Such trends cause a serious problem primarily in the north – eastern and south-western part of Slovenia, in which moisture deficiency in spring and summer months more and more often represents usual situation. Moisture deficiencies have been intensified in the last decades. In Maribor (and also within range of the whole north – eastern part of Slovenia) a record – breaking precipitation deficiency has been registered in the last years and after the year 2000 there have been just two years with moisture sufficiency.

Key words: temperature, precipitation, water balance, Slovenia, agricultural production, Ljubljana, Maribor deficiencies.
