Scar Reef lives up to its name with a wave that has left its mark on countless surfers—a perfect, mechanical right-hand barrel breaking over razor-sharp reef in Sumbawa. The wave peels with metronome consistency, offering flawless tube-riding opportunities, but the tradeoff is a bottom that sits terrifyingly close to the surface. Most surfers wear booties here, and even then, reef encounters are considered when, not if. The remoteness adds to both the appeal and the consequence; scoring Scar Reef uncrowded is the dream, but medical facilities are hours away.

Scar Reef is a reef break in Sumbawa, Indonesia, that mostly breaks right.
Scar Reef picks up swell from the S round to the SW, and it's best when it's coming straight out of the SSW. It starts working at around 1m and handles up to about 3.5m, with the sweet spot around 2.1 to 2.9m. Period matters too: aim for 14s or longer, as anything under 10s tends to be weak. These are the numbers our scoring uses, so treat them as a guide rather than a promise.
An E wind is dead offshore at Scar Reef, and anything from the NE round to the SE keeps it clean. The morning is typically the best window, roughly 6am to 11am. Light winds from other directions can still be fine; strong offshores can make it hard to get into waves.
Scar Reef is at its best around mid tide, roughly 0.5m to 1.5m on the local chart. Below 0.2m it gets dangerously shallow.
The most reliable run of swell at Scar Reef comes Apr to Oct. April-October dry season.
The water at Scar Reef averages around 27°C, so boardshorts or a rashguard will do. It shifts a few degrees through the year, so check the season before you pack.
Not really. It's rated 8/10 for difficulty and suits experienced surfers. The lineup is usually quiet (crowd 2/10). Very shallow reef. Name says it all - expect cuts.
