Discover Oceanside California
Oceanside is a coastal city located on California's South Coast. It is the third-largest city in San Diego County, California. The city had a population of 167,086 at the 2010 census. Together with Carlsbad and Vista, it forms a tri-city area. Oceanside is located just south of Marine Corps Base Camp Pendleton.
Originally inhabited by Native Americans, the first European explorers arrived in 1769. Spanish missionaries under Father Junipero Serra founded Mission San Luis Rey de Francia on a former site of a Luiseño Indian village on the banks of the San Luis Rey River. In the early 19th century, the introduction of farming and grazing changed the landscape of what would become Oceanside. The area—like all of California—was under Spanish, then in 1821 under Mexican rule, and then the U.S. in 1848.
In the late 1850s, Andrew Jackson Myers lived in San Joaquin County. A native of LaSalle County, Illinois, he returned in the late 1880s and lived in San Luis Rey. In 1882 Myers moved on the land that was the original town site for Oceanside. A patent for the land was issued in 1883 by the federal government. It was incorporated on July 3, 1888. The city hall as of the early 21st century stands on the former Myers homestead. The town post office contains an oil-on-canvas mural, Air Mail, painted in 1937 by Elsie Seeds. Federally commissioned murals were produced from 1934 to 1943 in the United States through the Section of Painting and Sculpture, later called the Section of Fine Arts, of the Treasury Department.
Oceanside is at 33°12′42″N 117°19′33″W (33.211566, -117.325701).
According to the United States Census Bureau, the city has a total area of 42.2 square miles (109 km2), of which 41.2 square miles (107 km2) is land and 0.9 square miles (2.3 km2) (2.23%) is water.
Traveling north on Interstate 5, Oceanside is the last city before Orange County. As the crow flies, it is roughly the same distance from Aliso Viejo as it is to downtown San Diego.
