San Luis - Arizona's Southernmost Border Town
San Luis is a city of approximately 31,500 people in Yuma County, sitting directly on the U.S.-Mexico border. The San Luis port of entry connects it to the much larger Mexican city of San Luis Rio Colorado, Sonora, which has over 200,000 residents. Daily cross-border traffic is heavy, with workers, shoppers, and families moving in both directions. The city is predominantly Hispanic, and Spanish is the first language for a large share of the population.
Agriculture dominates the economy around San Luis. The Yuma Valley's irrigated farmland, fed by Colorado River water through the Yuma Project canals, produces lettuce, broccoli, cauliflower, and other winter vegetables that supply a significant portion of the nation's produce during colder months. Many San Luis residents work in these fields or in the packing and distribution operations nearby.
The Fortuna Foothills and the Yuma Proving Ground lie to the north. San Luis itself is flat, low-elevation desert, with summer temperatures that frequently surpass 110 degrees. The commercial district along Main Street serves local needs, with shops, Mexican restaurants, and small businesses reflecting the binational character of the community.
The Marine Corps Air Station Yuma, located about 25 miles north, conducts training operations in the desert areas surrounding San Luis. The Cocopah Casino, operated by the Cocopah Indian Tribe, sits just north of the city and provides entertainment and employment for the wider Yuma County region.
The city incorporated in 1979 and has seen steady population growth driven by both natural increase and migration. Housing costs remain among the lowest in Arizona, which attracts families priced out of larger metropolitan areas.
