Carob is a typical coniferous tropical fruit which has specific requirements when it comes to climate conditions. It is a culture which tolerates high temperatures and insolation, and it is resistant to drought. The cultivation of carob is widespread along with other Mediterranean cultures. In some parts of Zadar County, the climatic features significantly differ as a consequence of a high relief diversity and the marine influence modified by mountain barriers. The aim of this thesis is to determine the limiting factors (temperature, precipitation) in the cultivation of carob, based on the meteorological data of Meteorological and Hydrological service, obtained from 5 stations in Zadar County (Zemunik, Zadar, Biograd, Kukljica and Božava). For the purpose of the assessment of the site's suitability, we have determined: Lang's rain factor, Monthly rain factor, and the sum of the active and effective temperatures. The weather conditions in Zadar County are significantly different from one part to another. In the coastal region, summers are mostly warm and dry, while winters are mild with a lot of rain, which are the characteristics of a real Mediterranean climate. Winters are more severe in Bukovica and Ravni kotari than on the coast and islands, which is a characteristic of a sub- Mediterranean climatic zone with slightly higher daily and annual temperature fluctuation. The main limiting climatic factor in the cultivation of carob in Zadar area is the occurrence of absolute minimum air temperatures.
