Best Conditions

Swell Direction: The ideal swell direction is SW (225°), with workable conditions from SSW to W (200°–270°). Swells outside this window will either miss the break or produce disorganized waves.

Swell Size: Crab Island needs a minimum of 1.8m / 6ft to start working and handles swells up to 3m / 10ft before conditions deteriorate.

Swell Period: Look for a swell period of at least 11 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 N (0°). The full offshore range spans NW to NE (315°–45°). 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 to high tide.

When to Go

Secondary Season: A secondary window opens April, September (Apr–Sep). While not as consistent, patient surfers can still score quality sessions during this period.

Water Temperature: Expect water temperatures around 13°C / 55°F. A 4/3mm or 5/4mm wetsuit is essential, with boots and gloves for extended sessions.
