Frequently Asked Questions

What tide is best at Yo-Yo's?

The Yo-Yo's profile favors mid to high tide, ideally between 0.7m and 1.8m on the local tide chart. Compare this preference with the forecast tide and local conditions before choosing a session.

What wind direction is offshore at Yo-Yo's?

The Yo-Yo's profile uses wind from NE (45°) as its preferred direction, with an offshore range of 15° to 75°. 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 Yo-Yo's?

The Yo-Yo's scoring profile favors swell from SW (200° to 230°), a swell-height range of 0.9m to 2.4m, and a reference period of 14s. These are model inputs, not guaranteed breaking-wave heights or a promise that the surf will suit every ability.

When is the best time of year to surf Yo-Yo's?

The main season at Yo-Yo's is Apr-Oct. A secondary window runs Nov, Dec, Jan, Feb, Mar. Best Apr-Oct (dry season, SE trades offshore). Swells year-round but wet season brings onshore winds.
