The Banzai Pipeline breaks at Ehukai Beach Park in Pupukea, about five miles from Haleiwa town. In winter, typically from November through February, northwest swells produce the hollow, powerful waves that have defined professional surfing. On a big day — fifteen feet or larger — the wave forms a perfect tube that allows riders to travel completely inside the wave for several seconds before either exiting cleanly or being driven into the reef below. The spectacle is visible from the beach, close enough to see the faces of the riders.
Watching Pipeline from the sand on a large swell day is one of the most dramatic spectator experiences in all of sport. The waves break with a physical percussion audible from well up the beach, the spray reaches twenty feet in the air, and the skill and nerve required to ride successfully in such conditions is impossible to fully appreciate without seeing it in person. The Triple Crown of Surfing, the sport's unofficial world championship, includes competitions at Pipeline each winter. Even outside competition season, when swells are running the beach will have a crowd of professional surfers in the water.
