Against what Mavericks likesWhy it is Flat, not Very Poor

Preferred tide and swell are surfer-consensus notes for this spot, not yet reviewed against measurements. Wind is judged by the general rule (light or offshore helps). No percent match: these are plain states and reasons.

Shallow is light, deep is dark; contours every few feet; the relief is exaggerated.

  • DepthCUDEM 1/9 arc-second (2022), relative to NAVD88. Depth shown is below the selected hour’s tide.
  • CoverageRock reef and headland shapes resolve well. Nearshore sandbars are interpolated flat in this dataset, so a beachbreak’s bar is not in the picture. A tile’s year is its publication, not the survey date.
Why it breaks like this3 swells at once, the seafloor spreads it, too deep for this swell

Read from the current hour (today at 8am). Each number, and what it does to the wave.

  • 3 swells at once

    3.5 ft at 11s from the WSW carrying 63% of the energy, plus 2.3 ft at 7s from the W (28%), plus 1.3 ft at 18s from the SW (9%).

    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 spreads it

    Kr 0.74 · 84% of modelled rays break.

    Energy is fanning outwards over the bottom here, so the wave arrives smaller than the open-ocean swell height suggests. Nothing is wrong with the forecast. The seafloor took the difference. Why two breaks a mile apart differ

  • Too deep for this swell

    4.1 ft of tide, and the reef needs a bigger swell to feel it.

    The reef sits deep enough that today's swell passes over without breaking. Swell size is not surf size. The bottom has to be shallow enough, relative to the wave, to trip it. How the tide moves the break

  • Wind is cross-shore

    9 mph from the NW, against a shoreline facing 251°.

    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.

Common questions4 questions about Mavericks
What is the best tide for Mavericks?
Mavericks 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 Mavericks?
W–NW (big) suits Mavericks 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 Mavericks good for beginners?
Mavericks suits expert surfers, over reef / boulder. 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 Mavericks?
reef / boulder (deep-water big-wave). 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 Mavericks on real 10-foot bathymetry instead of treating the seafloor as a slope.
