A more intense and mass production of medicinal aromatic plants, implementation of plantation system growth as well as the introduction of ISO standard system and agricultural technology require a complete and more detailed study in order to perform a safe and economic production.

The territory of the Republic of Serbia, although relatively small compared to the area of Europe and the whole planet, offers a significant climatological diversity conditioned by its position overlapped with various climatic influences (continental and maritime climate), relief and soil type diversity, exposition and other influences.

Thirty years series of meteorological parameters out of the network of 25 principal meteorological stations on the territory of Serbia were used in this paper. The average variation range and average occurrence of certain meteorological parameter values were taken into consideration in mean (average) value analyses.

The air temperature values in the surface layer of the atmosphere as well as the precipitation amount, being the two most significant climatic factors in plant production were treated in details. Other meteorological factors (insulation, wind and icing) do not represent the limiting meteorological factors and therefore they were not taken into consideration.
