Skill Level

  • Who it's for: Expert
  • Why: The reef is very shallow, the take-off critical, and the consequences of a wipeout are serious.

Hazards

  • Very shallow coral reef
  • Sharp, irregular reef bottom
  • Remote, limited medical support
  • Strong current on bigger swells

Local Tips

  • Hu'u Bay has a small surf camp scene, staying locally gives you real-time knowledge of when Scar Reef is at its best.
  • The wave fires best at 6–8ft; below that it's fun, above 10ft it becomes extremely serious.
