Rockstar

East Coast Nias, Indonesia
🪸Sharp reef

Rockstar is a flashy right reef break on the east coast of Nias, about 25km up the coast from the famous Lagundri Bay. The wave offers a fun alternative to the main bay breaks, with quality barrel sections and more room to move in the lineup. Less traveled than Sorake and Lagundri, it rewards those willing to make the extra drive with uncrowded sessions and tropical scenery.

Frequently Asked Questions

What tide is best at Rockstar?

The Rockstar profile does not specify a preferred tide stage. That does not mean tide has no effect: check local conditions alongside swell and wind.

What wind direction is offshore at Rockstar?

The Rockstar 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 Rockstar?

The Rockstar scoring profile favors swell from SW (210° to 250°), a swell-height range of 1.2m 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 Rockstar?

The main season at Rockstar is Apr-Oct. SW swell season (Apr-Oct), SE trade winds offshore

How do I get to Rockstar?

The spot profile lists GNS as a nearby airport. The estimated road transfer is 60 minutes. Fly to Gunungsitoli, drive east coast
