About Rockstar

Rockstar surf FAQ

Is Rockstar good for beginners?+

Rockstar is a reef break over coral, usually breaking in the 0.5–2.5m range, and how suitable it is for beginners really depends on the size and power on the day — not a fixed label. The coral bottom rewards some confidence in the water and awareness of what's beneath you, especially as the size picks up. Set the level to Beginner above and WaveCheck flags the smaller, cleaner hours worth paddling out for.

What's the best board for Rockstar?+

Different days call for different boards. Rockstar can get sizeable, so a shortboard comes into its own on bigger days, while a longboard still works when it drops small. Tap through the boards above to see the live score for whatever you'll be riding.

What are the best conditions for Rockstar?+

Look for 0.5–2.5m of swell from the E / SE / S with light offshore winds from the W / NW / N. The 5-day forecast above scores every hour, so you can spot the window at a glance.
