In recent years, it has been seen an increase in the wine grape production in the 'Fruit Circuit region, in the State of São Paulo. It is a region with great attractions associating tourism and wine production. The objective of this study was to evaluate the climatic potential of this region for wine grape production by means of the Multicriteria Climatic Classification System (Geoviticulture MCC System). The MCC System is based on three climatic indexes: heliothermal index, cool night index and dryness index and, it was calculated for the summer and winter growing seasons. During the summer growing season, the MCC System indicated that some areas in western of the region are warm, humid and have warm nights. The east-central area has a temperate night and in areas with higher altitude the climate found was warm temperate, without dry periods and temperate nights. For the winter growing season, the MCC System indicated high moisture values, with climatic classes ranging from hot, warm temperate and temperate. All these classes comprise very cold nights. The 'Fruit Circuit region showed humid condition during both summer and winter growing seasons.
