Greenbush

Mentawai, Indonesia
⚠️Shallow🪸Sharp reef😮‍💨Hold-downs🏝️Remote

Greenbush is the Mentawai's heaviest square barrel—a shallow left slab that only works on the highest spring tides but produces some of the thickest tubes in Indonesia when it does. The wave has three powerful sections that connect into an intense, ledging barrel over sharp reef. Timing is everything: show up at new or full moon spring tides, and you might score the wave of your life. Miss the tide window, and it's flat or too shallow to surf. High risk, high reward.
