Surf spot guide · North Shore Oahu, United States
Backdoor is a world-famous, heavy right-hand reef break on Oahu's North Shore.
Backdoor sits adjacent to Pipeline and breaks over a shallow, sharp reef, producing fast, hollow right-hand barrels. It is renowned for its powerful waves and is a proving ground for advanced surfers, especially during peak winter swells. The spot demands precise positioning and quick takeoffs, as the wave often closes out over shallow sections. Crowds are common, and local etiquette is strictly enforced. Backdoor is best surfed during the winter months when northwest swells are most consistent.
