The North Shore, in the context of geography of the Island of Oʻahu, refers to the north-facing coastal area of Oʻahu between Kaʻena Point and Kahuku Point. The largest settlement is Haleʻiwa. This area is best known for its massive waves, attracting surfers from all around the globe.The northern hemisphere winter months on the North Shore see a concentration of surfing activity, taking advantage of swells originating in the stormy North Pacific. Notable surfing spots include Waimea Bay and Sunset Beach.
The spot of Ehukai Beach, commonly known as the Banzai Pipeline, is the most notable surfing spot on the North Shore, and is considered a prime spot for competitions due to its close proximity to the beach, giving spectators, judges, and photographers a great view.
The North Shore is considered to be the surfing mecca of the world, and every December hosts three competitions, which make up the Triple Crown of Surfing.----------The Banzai Pipeline, or simply "Pipeline" or "Pipe," is a surf reef break located in Hawaii, off Ehukai Beach Park in Pupukea on O'ahu's North Shore. A reef break is an area in the ocean where waves crash once they reach the shallows of a reef. Pipeline is notorious and famous for its huge waves breaking in shallow water just above its sharp and cavernous reef, forming large, hollow and thick curls of water that surfers can ride inside of. There are three reefs at Pipeline in progressively deeper water further out to sea that activate at various power levels applied by ocean swells.
The location's compound name combines the name of the surf break (Pipeline) with the name of the beach fronting it (Banzai Beach). It got its name in December 1961 when surfing movie producer Bruce Brown was driving the North Shore with California surfers Phil Edwards and Mike Diffenderfer. Brown stopped at the then-unnamed site to film Edwards catching several waves. At the time, there was a construction project on an underground pipeline on adjacent Kamehameha Highway, and Diffenderfer made the suggestion to name the break Pipeline. The name was first used in Brown's movie Surfing Hollow Days. It also lent its name to a 1963 hit by surf music rockers The Chantays.
