Lineup Insights
The Wave
Best raw windows are long-period NW groundswells with SE-SSE offshore breeze and mid-to-rising tides that clear sand from the reef for punchier, hollow faces.

Sharp reef and rock shelves mean wipeouts carry a high injury risk and sessions attract experienced locals rather than crowds.
Access is near the Pipeline/Backdoor cluster so parking and lineups can be hectic on big days.
