A closeout is when a wave breaks all at once along its entire length, instead of peeling left or right. There’s no open shoulder to ride, just a wall of whitewater. It happens on steep, fast beach breaks or when the swell is too big for the spot’s bathymetry. They’re frustrating—you might get a steep drop, but then immediately get swallowed. The goal is to find a “peeling” wave that breaks in sections, giving you a long, rideable wall to carve up.
