Sketchy, very shallow right ledge that rarely shows but throws a square-floored barrel needing an air-drop entry, which makes it a bodyboarder favourite; NE-E swell. Experts. It works best on an ENE swell with SW winds around high tide. Watch for: very shallow rock shelf; experts.

Frequently Asked Questions

What tide is best at Boat Harbour?

The Boat Harbour profile favors high tide. Compare this preference with the forecast tide and local conditions before choosing a session.

What wind direction is offshore at Boat Harbour?

The Boat Harbour profile uses wind from SW (225°) as its preferred direction, with an offshore range of 180° to 270°. Wind speed matters too: light winds outside that range can still produce surfable conditions, while strong offshore winds can make takeoffs difficult.

What swell size and direction work best at Boat Harbour?

The Boat Harbour scoring profile favors swell from ENE (20° to 130°), a swell-height range of 1m to 3.3m, and a reference period of 12s. These are model inputs, not guaranteed breaking-wave heights or a promise that the surf will suit every ability.
