Timing is everything. Watch the sets and find the lulls. When a wall of whitewater comes, roll turtle (on a longboard) or duck dive (on a shortboard). For a duck dive, sink the nose deep, push the tail down with your foot, and use your knee to drive the board under the turbulence. Stay calm and conserve energy. Sometimes, it’s smarter to walk down the beach to a channel. Don’t fight the ocean; work with it.
