Guaymas (Spanish pronunciation: [ˈɡwajmas]) is a city and municipality located in the southwest part of the state of Sonora in northwestern Mexico.^[1] The city is located 117 km south of the state capital of Hermosillo, and 242 miles from the U.S. border, and is the principal port for the state.^[1][2] The municipality is located in the Sonora Desert^[3] and has a hot, dry climate and 117 km of beaches.^[1] The municipality’s formal name is Guaymas de Zaragoza and the city’s formal name is the Heróica Ciudad de Guaymas.^[1]

The city proper is mostly an industrial port, with nearby San Carlos being the major tourist attraction for its beaches.^[4] The city also has a well-attended annual carnival, which has been held since 1888.
During the Mexican Revolution, the first ever aerial bombardment of a naval target occurred just off the coast of Guaymas: in 1913, five military ships belonging to Federal forces appeared in the bay, and General Alvaro Obregon of the rebel army ordered the bombing of these ships using the aircraft “Sonora.”^[10]

The first modern port facilities were built in 1925 for the Mexican navy. In 1942 a commercial pier and warehouse were built at La Ardilla. Guaymas’ importance as a port grew in the 1950s, and in 1961, a pier for the national oil company PEMEX was built. A naval ship repair station, called the Varadero Nacional, and silos for the export of grain, called the Almacenes Nacional de Depósito, were built in 1964.

Ferry connection with the city of Santa Rosalía, Baja California Sur was established in 1972. In the 1980s, a number of private construction projects further enlarged the port, including those built by the Compañía Mexicana de Cobre, Cementos Tolteca and Compañía Mexicana de Ácido Sulfúrico.^[1] Due to changes in Mexican maritime law, a private company under contract to the government, Administración Portuaria Integral de Guaymas, took over port operations in 1995.^[10]
