Number Fours

Number Fours is an exposed reef break off Fort DeRussy in Waikiki, known for quality surfing when south swells build. The wave setup can deliver both lefts and rights, and the break is described as reasonably consistent—though it tends to “come alive” primarily when the surf gets bigger. Access is by paddling out from Fort DeRussy Beach Park, about a half-mile offshore. Because it sits far out over deeper water for Waikiki, it’s more demanding physically and more adventurous than many inner options, which also helps act as a natural filter for crowd density. Wind-wise, the cleanest conditions are reported with offshore North or Northeast trade winds. On the right wave days, surfers can find longer, peeling rides. Reported preferences are for mid tide, and the working swell window is given as roughly 1.0 to 3.0 meters from the south (with south/southwest/south-southeast directions cited as optimal). For larger sets, the break is described as holding its shape better than many inner Waikiki spots. Safety is a key consideration: the break’s reef, rocks, and shallow coral sections create injury risk, and it’s specifically noted as one of the more “sharkier” breaks in the Waikiki area due to its proximity to deeper offshore water. In addition, strong currents can occur during large swells and tidal changes, so be prepared for a long paddle and keep an eye on incoming sets—especially if conditions are cleaning out the lineup.
