Indicators is a world-class right reef break at Lagundri Bay in South Nias, located around the point from the famous Sorake Beach. The wave produces incredible barrels when a solid SW swell pushes in at high tide, but becomes extremely dangerous at low tide when the reef is exposed. The rising high tide is the sweet spot—when Indicators turns on, it rivals any right-hander in Indonesia for raw barrel quality.

Frequently Asked Questions

What tide is best at Indicators?

The Indicators profile favors high tide, ideally between 1m and 2m 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 Indicators?

The Indicators profile uses wind from N (0°) as its preferred direction, with an offshore range of 330° to 30°. 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 Indicators?

The Indicators scoring profile favors swell from SW (200° to 230°), a swell-height range of 1.5m to 3m, 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.
