Against what Twin Lakes / Seabright 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.

The break
The seafloorSand beside the harbour jetty
Shallow is light, deep is dark; contours every few feet; the relief is exaggerated.
- Bottomsand beside the harbour jetty
- DepthCUDEM 1/9 arc-second (2023), 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 thisOne swell, uncrossed, the seafloor is neutral here, where it trips
Read from the current hour (today at 5am). Each number, and what it does to the wave.
One swell, uncrossed
3.7 ft at 15s from the SSW 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 is neutral here
Kr 0.96 · 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
3.2 ft of tide; waves are breaking in about 9 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 179°.
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 3 min, roughly 11 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.

Common questions4 questions about Twin Lakes / Seabright
- What is the best tide for Twin Lakes / Seabright?
- Twin Lakes / Seabright 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 Twin Lakes / Seabright?
- S–SW suits Twin Lakes / Seabright 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 Twin Lakes / Seabright good for beginners?
- Twin Lakes / Seabright suits beginner-intermediate surfers, over sand beside the harbour jetty. 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 Twin Lakes / Seabright?
- sand beside the harbour jetty. 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 Twin Lakes / Seabright on real 10-foot bathymetry instead of treating the seafloor as a slope.
