- [The Office](https://yosurf.app/spot/the-office): Sumba; Reef left; levels beginner, intermediate, advanced; Reef left with rather soft, long walls, considered the main peak in Kalala Bay (southeast Sumba), distinct from Racetrack and Five-O. Intermediate to advanced level, season May-September.
- [Raijua Left](https://yosurf.app/spot/raijua-left): Savu and Rote; Reef left; levels beginner, intermediate, advanced; On Raijua's arid, NW-facing coast (Savu islands). When a big, more westerly swell wraps around the Bombie reef at the western tip, a long, very fast left barrels for long sections at low tide. A serious wave.
- [Raijua Wedge](https://yosurf.app/spot/raijua-wedge): Savu and Rote; Reef left; levels beginner, intermediate, advanced; Tucked deep into Raijua's western tip. An unusual wave relying on a strong swell bounce off adjacent cave-pocked cliffs; like its Californian namesake, a strong side-wash meets the incoming swell at a 90-degree angle.
