Bankvaults
Also known as: Bankies
The Mentawai's premier heavy right and a genuine swell magnet - the Playgrounds go-to when everywhere else is small, and a broken-board rite of passage.
Best time to surf
Works year-round; best barrels Apr-Oct
Shoulder season: Good - one of few cluster waves that works year-round; still fun on Nov-Feb swells
The wave
Break type: Reef break
Bottom: Reef (coral) - big reef, breaks in 2-3 take-off zones
Wave direction: Right
Typical wave length: Long - thick, square barrels; middle section can connect to the inside; the Mentawai's biggest right-hand tubes on size
Ideal swell: Swell magnet - any direction; ideal ~4-8ft, holds to triple overhead; rarely flat
Ideal wind: Offshore N / NW
Working tide: Mid tide (too high and barrels won't form; too low and the reef is a hazard)
Difficulty & skill
Difficulty (1-5): 4 (5 when big / triple-overhead - heavy, thick, critical take-off; broken boards common)
Skill level: Advanced (intermediate+ from head-high per operators, but a true advanced/expert wave at size)
Options for a mixed group: Nipussi (lighter safer right a stone's throw away), Pitstops (all levels), Beng Bengs (all levels)
Safety & hazards
Heavy thick lip, wide sets catching the inside, long turbulent hold-downs, big reef, broken boards/leashes
Resort first-aid / sat / Starlink; Tuapejat clinic; boat evacuation to Padang then flight
Crowd, access & conditions
Crowd & localism: 5-20 surfers; the big reef spreads people out; no resident locals; watch wide sets
Access & parking: Boat access only; ~10 min from Playground Surf Resort (Masokut), ~5 min from Driftwood; central to most cluster camps
Surf schools & rental: No school (advanced wave); guided by Playground Surf Resort, Driftwood, Mentawai Surf Retreat; charters Mentawai Surf Charters / World Surfaris / Perfect Wave
Water temp & wetsuit: ~28-29 C year-round; boardshorts / rashguard, no wetsuit (thin reef top for sun/coral)
Crowds, access and local conditions change - confirm locally before you paddle out.
