What is the best tide for Upper Trestles?

Upper Trestles 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 Upper Trestles?

S–SW in summer, W–NW in winter suits Upper Trestles 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 Upper Trestles good for beginners?

Upper Trestles suits advanced surfers, over cobblestone point. 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 Upper Trestles?

cobblestone point. 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 Upper Trestles on real 10-foot bathymetry instead of treating the seafloor as a slope.

Against what Upper Trestles likesWhy it is Good, not Epic

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.

Why it breaks like thisOne swell, uncrossed, the seafloor focuses it, where it trips

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

One swell, uncrossed
2.0 ft at 14s from the SW and nothing significant crossing it.
A single train is the cleanest case there is: the sets arrive from one angle, so the peak should sit in the same place each time instead of wandering. Why period matters more than height
The seafloor focuses it
Kr 1.13 · 82% of modelled rays break.
Contours underneath are bending wave energy together into a band. That concentration is the peak, and it's why this spot can be noticeably bigger than its neighbours on the same swell. Why two breaks a mile apart differ
Where it trips
3.4 ft of tide; waves are breaking in about 6 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 offshore
15 mph from the ENE, against a shoreline facing 226°.
Blowing from the land into the face, holding the wave up as it stands. That is what grooms it and gives you the clean, hollow version of this spot.
How the sets come
About one set every 2 min, roughly 7 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.
