Huntington Beach is a seaside city in Orange County in southern California. As of the 2000 census, the city population was 189,594. It is known for its long 14 km (8.5 miles) beach, mild climate, and excellent surfing. The waves are a unique natural effect caused by edge-diffraction of ocean swells by the island of Catalina, and waves from distant hurricanes.
Huntington Beach is the site of the world surfing championships, held in the summer every year. The city is often referred to as "Surf City" because of this high profile event, its history, and culture of surfing.
