The reef faces east but works best with southwest swell wrapping around the point, generating medium-sized waves that peel across the shallow structure. This spot attracts a solid mix of locals and visiting surfers who appreciate the reliable conditions and scenic coastal setting.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
