Huntington Beach is a seaside city in Orange County in Southern California, located 35 miles southeast of Downtown Los Angeles. The city is named after American businessman Henry E. Huntington. The population was 189,992 during the 2010 census, making it the fourth most populous city in Orange County, the most populous beach city in Orange County, and the seventh most populous city in the Los Angeles-Long Beach-Anaheim, CA Metropolitan Statistical Area. It is bordered by Bolsa Chica Basin State Marine Conservation Area on the west, the Pacific Ocean on the southwest, by Seal Beach on the northwest, by Westminster on the north, by Fountain Valley on the northeast, by Costa Mesa on the east, and by Newport Beach on the southeast.
Huntington Beach is known for its long 9.5-mile stretch of sandy beach, mild climate, excellent surfing, and beach culture. The ocean waves are enhanced by a natural effect caused by the edge-diffraction of open ocean swells around Santa Catalina Island.
