How Las Tunas works

Cobble and reef peaks held together by old groins along PCH — an unglamorous but consistent Malibu-area option when First Point is a parking lot.

Common questions about Las Tunas

What is the best tide for Las Tunas?
Las Tunas works best on mid tide. Tide matters because depth is what trips a wave: as the water fills in, the break slides shoreward onto a different part of the bottom, and over a shallow bank enough water stops it breaking at all. Our forecast solves each hour at that hour's real water level rather than assuming one.
What swell direction is best for Las Tunas?
S–SW suits Las Tunas best. The direction that matters is the one at the break, not the one on the buoy: the seafloor bends swell on its way in, so a spot can work on an angle the open coast is missing. We model that bending for each break rather than reporting the offshore direction.
Is Las Tunas good for beginners?
Las Tunas suits intermediate surfers, over cobble and reef, with groins. That is the wave this bottom makes on an average day, and it moves: the same break is a different proposition on a bigger swell or a different tide, so read the day's forecast rather than the label.
What is the bottom like at Las Tunas?
cobble and reef, with groins. It is the reason this break behaves the way it does: the shape of the seabed decides where the swell focuses, where it trips, and whether it spills or pitches. We model Las Tunas on real 10-foot bathymetry instead of treating the seafloor as a slope.
