The territories of Cusco are under the macro-climatic influence of great masses of air coming from the South Eastern forest, the Altiplano, and even from the distant region of Patagonia. The winds of the southern jungle imply immense masses of moisture-laden air, which are driven by the east trade winds.
The winds coming from the Bolivian Peruvian Altiplano are rather cold and dry, as are those coming from Patagonia and usually involving larger scale events. These enter the south eastern area. On the other hand, the local winds that are generated in the valleys and the plains of Cusco have the function of distributing heat and humidity throughout the day. In general, there are two climatic seasons: the rainy season, from November to March and the dry season, from April to October.
