What the seafloor does to this wave
A cut straight out from Las Tunas, solved on the real seafloor at this hour’s swell and tide.
Why Las Tunas looks like this right now
The numbers above, and what each one is actually doing to the wave.
3 swells at once
1.5 ft at 12s from the SSW carrying 57% of the energy, plus 1.2 ft at 17s from the SSW (35%), plus 0.5 ft at 5s from the WSW (7%).
The shorter, steeper train is carrying most of the energy here, so expect a choppier, less organised lineup than the longest period in the list would suggest on its own. Why period matters more than height →
The seafloor is neutral here
Kr 0.93 · 75% of modelled rays break.
Energy arrives roughly as it left deep water: this bottom neither concentrates the swell nor fans it out, so what the buoy sees is close to what you get. Why two breaks a mile apart differ →
Where it trips
4.0 ft of tide; waves are breaking in about 4 ft of water.
A wave breaks when the water gets shallow enough relative to its height, so that depth is a contour on the seafloor, and the tide slides the whole break up and down it through the day. Same swell, different spot, a few hours apart. How the tide moves the break →
Barely any wind
5 mph from the SSE, against a shoreline facing 186°.
Too light to shape the face either way. At this speed the wave's own texture wins, whatever the direction.
How the sets come
About one set every 1 min, roughly 8 waves in it.
Swell arrives in groups, not evenly. That spacing is what you are really timing your paddle-out to, and it's why the lineup can look flat for minutes and then produce five waves at once. Why period matters more than height →

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.
