What the seafloor does to this wave
A cut straight out from Gray Whale Cove, solved on the real seafloor at this hour’s swell and tide.
Why Gray Whale Cove looks like this right now
The numbers above, and what each one is actually doing to the wave.
3 swells at once
1.8 ft at 13s from the WSW carrying 50% of the energy, plus 1.7 ft at 5s from the WNW (44%), plus 0.6 ft at 8s from the W (6%).
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 0.90 · 73% 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
4.7 ft of tide; waves are breaking in about 5 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 →
Wind is cross-shore
6 mph from the NW, against a shoreline facing 259°.
Running across the face rather than into or against it. Less destructive than a straight onshore, but it puts a texture on the wall and can make the peak harder to read.
How the sets come
About one set every 1 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 →

Common questions about Gray Whale Cove
- What is the best tide for Gray Whale Cove?
- Gray Whale Cove 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 Gray Whale Cove?
- SW–W suits Gray Whale Cove 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 Gray Whale Cove good for beginners?
- Gray Whale Cove suits intermediate surfers, over sand. 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 Gray Whale Cove?
- sand (exposed). 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 Gray Whale Cove on real 10-foot bathymetry instead of treating the seafloor as a slope.
