Best Conditions

Swell Direction: The ideal swell direction is SW (220°), with workable conditions from SSW to WSW (200°–250°). Swells outside this window will either miss the break or produce disorganized waves.

Swell Size: Bankvaults needs a minimum of 1m / 3ft to start working and handles swells up to 3m / 10ft before conditions deteriorate.

Swell Period: Look for a swell period of at least 10 seconds, with 14 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 (80°–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. Optimal tide range is 0.5m–1.5m.
