Rockslide is a reef break that peels both left and right over a rock ledge. It draws swell from the south through west-southwest to northwest, with a west (W) swell the best match, and it works from 0.6 m / 2 ft to 2.4 m / 8 ft.
Look for east (E) offshore wind to clean it up. The reef breaks on low and mid tide, with a rising tide generally the better call.
Rockslide is usually best with swell from south through west-southwest to northwest (S-WSW-NW), ideally west (W) around 0.6 m / 2 ft to 2.4 m / 8 ft, east (E) offshore wind, and low to mid tide.

The forecast table (the section on the page with all the numbers) is designed to pack as much information in the screen as possible. Although intimidating at first, it will help you make informed decisions about the waves faster, trust me :D. The table consists of roughly four sections, time and predictions, wind, waves, and tides:
Here we show the forecast thour and the overall surf quality prediction. This is determined based on the wave, wind and tide quality prediction. These individual predictions can be found on the forecast map.
The first row on the table (with the 💨 icon) shows wind speed, direction and gust. The more the wind speed the more aggressive the color (from blue, green, orange to red).
The waves section consists of three rows, one for wave height and direction, one for period and one for wave energy. Our algorithm chooses the "dominant wave" using spot-adjusted surf energy (depth + directional fit). This is usually the first swell partition, but during local storms it can switch to wind waves. If that happens, values are shown in gray and italic.
The small letter in the wind and wave cells shows how closely the weather models we blend agree for that hour.
For wind we compare each model's wind vector, plus gusts where every model reports them. For waves we compare height, period and direction of the matched swell systems.
It is a measure of model agreement, not a probability that the forecast is right.
The tide section consists of a row with the actual heights per hour (measured at the half hour) and a table that displays the flow of the tide and the extremes (lows and highs).
The forecast map consists of arrows. These arrows represent all wave partitions (swell partitions and wind wave partition) and the wind. This allows you to see things like: a secondary swell or wind waves messes up the surf, or the wind is just a tick offshore so very surfable. Click a metric label in the bottom left to bring that arrow to the front — handy when arrows overlap.
Short on time? Focus on wave energy. It’s the best single metric to gauge how big and powerful the waves will be.
Click any table cell to jump to that forecast hour. The map will update with forecast arrows, so you can see if wind and swell direction are lining up.
Use the table sidebar to switch units for height and speed.

Surfnerd blends multiple global and local wind and swell models using advanced interpolation and spatial techniques to create an "ensemble" forecast. Forecasts are refreshed hourly.
Our AI-driven algorithm scores surf quality, shown by green, orange, and gray dots. Each forecast hour is rated for wind, swell, and tide quality, then combined into an overall score. Here’s the scale:
Session logs also feed the algorithm — the more you log, the smarter your forecasts get.
With Surfnerd, no more "you should have been here yesterday"
