What is the best tide for Bird Rock?

Bird Rock works best on mid to high 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 Bird Rock?

W–SW suits Bird Rock 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 Bird Rock good for beginners?

Bird Rock suits advanced surfers, over shallow rock reef. 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 Bird Rock?

shallow rock reef. 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 Bird Rock on real 10-foot bathymetry instead of treating the seafloor as a slope.

Why Bird Rock looks like this right now

The numbers above, and what each one is actually doing to the wave.

Two swells at once
1.5 ft at 17s from the SW carrying 81% of the energy, plus 0.8 ft at 6s from the W (19%).
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 0.91 · 65% 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
5.7 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 →
Barely any wind
3 mph from the NNW, against a shoreline facing 236°.
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 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 Bird Rock works

A rock reef off the Bird Rock bluffs that gets fast and shallow — best on a mid-to-high tide when the reef stops showing its teeth.

Bottom: shallow rock reef
