The geography of the area consists of rugged mountains, semi-flat areas and flat areas, which are part of the Costa Grande region. Rugged mountains cover about 70% of the surface, mostly in the north and center, formed by the Sierra Madre del Sur and reach a height of 2,500 m (8,200 ft) above sea level. Semi-flat areas cover about 20% of the surface and are mostly located just north of Highway 200 and are mostly rolling hills. Flat areas cover the rest and are concentrated in the west, southeast and the coastline. Major rivers are the Coyuquilla, Petatlán and San Jeronimito, with a number of arroyos such as the Camotal, La Morena, El Comalate and Coyuca. There are small lakes and lagoons such as the Santiago, Estero Valentín, Salina el Cuajo and Tular. The variations in altitude lead to three types of climate: semi-humid, semi-hot and hot. The first is mostly located in the north along the border with Coyuca de Catalán. The second is in the center and the last is along the coast. In all these climates, there is a rainy season, which lasts from June to October. There are also rains in November and December.
