A hollow, ledgey left that rears up near a headland on Aceh's remote west coast, Cement Factory demands a sizeable SW swell to fire and rewards the effort with long, high-walled runs over coral reef. It needs at least 223-degree magnetic swell direction and genuine size to wrap this far up the coast, which means it delivers only a handful of times per season. SW to WSW groundswell at 4-8ft is the target window, with offshore winds from the E to SE. Crowds are essentially non-existent given the access challenge and fickle conditions. Bottom: coral reef. Season: peak SW swell months, May through September. Consistency: very low, a few swells per season. Bring a step-up and be fully self-sufficient, no facilities exist near the break and the road in is rough, requiring over two hours of driving from the nearest reference point at Scar Reef.

About this break

What it's actually like

Crowd & Localism

This spot sees almost no one. The combination of difficult access, an uncertain GPS location, and a very narrow swell window keeps crowds at zero. There are no known localism issues, but respect any surfers who made the same effort to get here.

Access & Facilities

The approach involves a rough two-hour drive up Aceh's west coast from Scar Reef, on roads that are genuinely difficult. The exact GPS coordinates are uncertain, ask locally and look for the prominent cement factory as a landmark. Bring all your own water, food, and first aid. No surf infrastructure of any kind. Coral reef means urchins and reef cuts are real hazards on a wipeout.

Nearby Alternatives

Scar Reef is the logical fallback when Cement Factory isn't on, offering a more consistent left-hand reef setup in the same general swell window. Other breaks along Aceh's west coast headlands may also show signs of life on the same SW swell pulse, worth scouting on the drive in.
