What the seafloor does to this wave
A cut straight out from Black's Beach, solved on the real seafloor at this hour’s swell and tide.
Why Black's Beach looks like this right now
The numbers above, and what each one is actually doing to the wave.
Two swells at once
1.2 ft at 17s from the WSW carrying 73% of the energy, plus 0.7 ft at 6s from the W (27%).
The long-period train is the one building your wave. It holds the most energy and reaches deepest. The shorter ones cross it, which is what makes the surface look busy and the takeoff shift around. Why period matters more than height →
The seafloor is neutral here
Kr 1.03 · 92% 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
3.7 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
1 mph from the WNW, against a shoreline facing 267°.
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 2 min, roughly 6 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 Black's Beach works
The Scripps and La Jolla submarine canyons run almost to the beach here and focus swell onto the bars, so Black's can be twice the size of everything around it. Steep, hollow, and genuinely heavy on a big day.

Common questions about Black's Beach
- What is the best tide for Black's Beach?
- Black's Beach works best on low to 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 Black's Beach?
- W–NW groundswell suits Black's Beach 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 Black's Beach good for beginners?
- Black's Beach suits advanced surfers, over sand, fed by the head of the La Jolla submarine canyon. 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 Black's Beach?
- sand, fed by the head of the La Jolla submarine canyon. 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 Black's Beach on real 10-foot bathymetry instead of treating the seafloor as a slope.
