📍 Local Knowledge

Number Fours in Oahu is an exposed reef break with reasonably consistent surf, best during Summer, especially in May. It works optimally when a South-southeast swell combines with North offshore winds, with most surf coming from groundswells. The break offers a choice of left and right reefs and performs well at all tide stages. When the surf is up, it can get quite busy. Surfers should take care of rocks, obstacles, locals, and sharks.
