Savanna environments belong to the general climate type known as tropical and subtropical grasslands, savannas, and shrublands. This climate type is characterized by a distinct wet season and a dry season, with the dry season lasting several months. The mean annual temperature in these regions typically ranges between 64 and 86 degrees Fahrenheit (18 to 30 degrees Celsius). Precipitation levels vary depending on the location, but most savanna regions receive between 30 and 50 inches (75 and 125 centimeters) of rain per year. Savannas are typically found in Africa, South America, and Australia, and they support a wide variety of plant and animal life.
