Frequently Asked Questions

What tide is best at Moon Island?

The Moon Island profile favors low tide. Compare this preference with the forecast tide and local conditions before choosing a session.

What wind direction is offshore at Moon Island?

The Moon Island profile uses wind from W (270°) as its preferred direction, with an offshore range of 225° to 315°. 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 Moon Island?

The Moon Island scoring profile favors swell from SE (70° to 190°), a swell-height range of 0.8m to 2.5m, and a reference period of 13s. These are model inputs, not guaranteed breaking-wave heights or a promise that the surf will suit every ability.
