Best Conditions

Swell Direction: The ideal swell direction is S (190°), with workable conditions from SSE to SW (155°–225°). Swells outside this window will either miss the break or produce disorganized waves.

Swell Size: Kewalos needs a minimum of 0.9m / 3ft to start working and handles swells up to 1.8m / 6ft 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 N (10°). The full offshore range spans NNW to NE (340°–55°). 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.

When to Go

Primary Season: The prime window at Kewalos runs May, June, July, August, September (May–Sep). This is when swell consistency and direction align most reliably with the break.
