One of Indonesia's heaviest, roundest left barrels, breaking over shallow coral in the southern Mentawai and only on a big high tide.
Greenbush breaks in the Pagai islands, at the southern end of the Mentawai chain, into a horseshoe bay lined with thick jungle and almost no beach. There is no road to it and no camp on the point. You arrive by boat, anchor up, and look at a left running down a shelf of live coral with two rocks standing proud of the water halfway along it.
On the wrong day it looks like nothing much. On the right day it produces some of the biggest and roundest barrels in Indonesia, which is why so many famous Indonesian tube shots were taken here. It is also famously fussy. Greenbush wants a big south swell, a high tide with real water over the reef, and a north or east wind to hold it open. Plenty of boats have motored past on a promising forecast and kept going.
The wave
The take-off is the first problem. Swell comes out of deep water and hits the shelf all at once, so the lip is already throwing while you are still getting to your feet. Airdrops here are normal rather than unlucky, and the ones that go wrong go wrong onto reef. Sitting deep is the only way to make the good ones, which is the uncomfortable part of the whole equation.
From there it runs left for up to a hundred metres, and the barrel is the whole point. It is thick lipped and genuinely round rather than a fast little almond, and the better ones hold you in long enough to watch the wave change shape around you. Halfway down you pass the two rocks, close enough to the face to concentrate the mind. Then comes the end section, standing up over reef that is barely covered, either spitting you out into the channel or shutting down a few metres short.
Size and tide change it completely. Below a few feet it is a non-event. It only does what it is famous for with proper swell behind it, overhead and up. Tide matters just as much. It wants high water, and the best sessions tend to fall on the spring tides around a new or full moon when there is enough depth over the reef. As the tide drains, the sections square up, the reef comes closer and the end bowl starts breaking on coral you can see.
Conditions at a glance
- Wave type: Left-hand reef break
- Best swell: South to south-west, with real period behind it
- Best wind: North through north-east and east, or a still, glassy morning
- Best tide: High tide only, ideally a rising push on the spring tides around a new or full moon
- Best size: Overhead and up. It needs roughly 5 to 12ft of swell before it properly switches on
- Season: April to October, with April to June often the pick for lighter winds and bigger south swells
- Crowd: Greenbush is rarely crowded in the ordinary sense, because it is boat access only and does not break often. When the forecast does line up the charter fleet converges, and you can find ten to twenty surfers on it, most of them very good.

Who it suits
This is an expert wave and we would rather say so plainly than dress it up. If you are not comfortable taking off late and behind the peak, riding deep and coming out the other side without an escape route, Greenbush is not the place to find that out. A bad wave here does not mean a long swim. It means live coral under very little water, hours from a hospital, and reef cuts that infect fast in the tropics.
Intermediate surfers are far better off watching. Sitting in the channel while Greenbush does its thing is one of the great sights in Indonesian surfing, and there is no shame in saving your energy for the wave down the coast. Even very good surfers pick their moment here, sit through sets and paddle in when the tide turns. If you do go out, wear booties, ride a board you trust in the barrel, and accept that two good ones is a good score.
How to surf Greenbush with WaveBorn
Greenbush is a boat wave. There is no land camp on it, so reaching it means being on something that can move when the forecast points south. Ombak Kabau is built for exactly that: eleven nights aboard, ten surf days, up to ten guests, roaming the entire Mentawai chain and going where the swell is best on the day. If a solid south pulse lands on a spring high tide, that is where we take the boat.
Odyssey Mentawai does the same job with a different feel. She is a 46ft catamaran for up to eight guests with a surf pro on board, ranging across the Mentawai and the quieter Tello Islands. Having someone aboard reading the tide and calling the session counts for more at Greenbush than almost anywhere else, because the gap between a memorable day and a trip to the first aid kit is often forty minutes of water. What we will not do is promise you Greenbush. It has to be earned by the forecast.

Nearby breaks
Greenbush sits within easy reach of Macaronis, Thunders, Roxies and Rags Left , which is what makes this part of the archipelago so productive: if the wind or swell does not suit one reef, another is usually working a short ride away.
Conditions here are a guide, not a guarantee. Our crew reads the swell, wind and tide each morning and puts you on the break that matches your surfing that day. See the full Mentawai surf spots guide or browse every break we surf.
