Conditions
Modelled swell, wind, tide, and a seven-day outlook. This is a forecast, not a live observation at the reef.
A thick-lipped left barrel on the southwestern edge of Pulau Pagai Utara — one of the deepest, squarest tubes in the southern Mentawai when it lines up. Boat-only and fickle next to Macaronis, but a cornerstone of the same Pagai rotation for expert shortboarders.
Expert barrel reef over shallow coral. Not for inexperienced surfers; Macaronis is the more consistent neighbour when Greenbush is off.
