Sonoran Desert surrounds Marana, where 51,000 residents occupy terrain northwest of Tucson with elevation around 2,000 feet. Desert climate means scorching summers regularly exceeding 105°F and mild winters averaging 52°F, with just 11 inches of annual rainfall. Saguaro cacti dot hillsides, while Tortolita Mountains rise northeast and Santa Cruz River valley defines the eastern boundary. Monsoon season brings July-August thunderstorms, briefly transforming the arid landscape with temporary moisture.
