Scar Reef
Also known as: -
Arguably Sumbawa's best wave - a freight-train left down razor reef; keep the pedal down, backdoor the sections, and expect scars.

Dry season May-Oct (best ~Sep)

Typical wave length: Long - runs up to ~150m with multiple barrel sections
Ideal swell: SW groundswell; handles big swell (bring a step-up)

Working tide: Best mid-to-low for length, but safer/more makeable pushing to high (low = backdoor close-outs)
