The Aztec climate was mild or temperate. This was because the Aztec chose to live in Central Mexico, with the majority of them living in the Mexican Valley.
Since the Mexican Valley was surrounded by mountains and lakes, the weather was mostly mild or temperate. Many of the areas where the Aztec lived were swampy or dry. Under normal circumstances, the water from the land was not sufficient to sustain the crops that the Aztec planted due to the land's condition. To solve this problem, theAztec invented their own progressive irrigation system for watering their various crops. This irrigation system was also used for transporting their goods.
