Best Conditions

Swell Direction: The ideal swell direction is NW (305°), with workable conditions from WNW to NW (290°–320°). Swells outside this window will either miss the break or produce disorganized waves.

Swell Size: Rockpile needs a minimum of 1.8m / 6ft to start working and handles swells up to 4.6m / 15ft before conditions deteriorate. When it maxes out, expect powerful, heavy-water conditions.

Swell Period: Look for a swell period of at least 12 seconds, with 16 seconds being the sweet spot. Longer periods deliver more organized, powerful waves with better shape.

Wind: True offshore here blows from the ESE (120°). The full offshore range spans E to SSE (90°–160°). Glassy conditions under 4km/h from any direction also produce excellent surf. Plan for early morning dawn patrol sessions.

Tide: This spot works best at mid tide.
