A shallow, north-facing North Shore reef that gives both lefts and rights - powerful when winter NW groundswells line up but often meek in summer, with a real reef-strike consequence on heavy days. Get the latest surfing conditions, forecast, and tide details for Stone Zone/Monster Mush in Hawaii.

As of:
Tide curve (forecast)
0.4 ftrising
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.
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.
