Relief influences on climate, lead to a wide environmental conditions, even more than latitude. The Köppen Method, one of the most used, is of physical type, and leads to excellent approaches to real climate conditions, , but it doesn't consider in a full dimension the water-soil-cultivated plant-atmosphere interaction, being that these factors decide so much the natural vegetation as crops. The periods with freezing temperatures or with high frost risk, and the duration of dry months, all of them are decisive for agriculture. These risk factors are considered in the Papadakis Method, which allows evaluating the potentiality and limitations of the climatic areas, related to crops. In this work an application is made of this method on a wide region in Northwest Mexico, where agriculture is very important, and the obtained results converge to define that existent climatic groups are the following, according to Papadakis Method: 1.4: continental savanna 1.5: tropical semi-arid 1.9: tropical with fresh winter 2.3: medium-cold highland 4.2: continental subtropical 4.3: continental semitropical
