Selected as the 2028 LA Olympics surfing venue and longtime WSL Championship Tour stop. The wave is rippable and consistent but the crowd and competition-level lineup make it effectively advanced. The 15-minute walk from the parking lot is the only thing keeping numbers in check.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
