Castles in Oahu is an exposed beach and reef break that offers optimal surfing conditions mainly in summer. It works best with offshore winds from the north-northeast and receives a mix of groundswells and windswells, with the ideal swell direction from the south-southeast. The reef breaks left, and the spot is rarely crowded. Surfers should watch out for rocks and other hazards.
