Rock surf guide

Rock is a surf spot located near Anjou Port. It's known for its right-hand barrels, which can be pretty fun on the right day. That said, it's less consistent than some other spots in the area, like Hungry, so you might not always find great waves here. The wave quality tends to attract local experts who are looking for a challenge. Just keep in mind that the conditions can be a bit hit or miss.

This spot works best with a big southeast swell, but east swells can hit it a bit straight. Ideal wave heights are around head-high or more, where you can catch nice barrels, but on bigger days, the wave tends to become more of a wall. Rock handles swell sizes starting from about 3 ft (1 meter) and can really come alive when the tide is low, mid, or high, but you’ll want to keep your skills at an expert level to navigate the uneven reef effectively.

If you're planning to surf here, the best wind direction is from the southwest, which helps create cleaner waves. Just be cautious of the rocks in the area; they can create some hazards if you're not paying attention. Overall, it's a spot for those looking to test their skills against a less forgiving wave.

Wind certainty

Wind certainty tells you how much the weather models agree on the forecast.

  • High certainty: Models agree closely; forecast is reliable.
  • Medium certainty: Some disagreement; conditions may shift slightly.
  • Low certainty: Models diverge; treat forecast with caution.

We calculate this by comparing wind speed, gust and direction from multiple models (like GFS, ECMWF, Arome, and Harmonie) and seeing how closely they match. They are weighted, meaning that some models count more than others, depending on how good they are for a certain spot.

Forecast Cheat Sheet

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.

Log your surf sessions to compare forecasts with real sessions and sharpen future predictions.

On the map, click a metric label to bring that arrow to the front — handy when arrows overlap.

Models and Updates

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.

Surf Predictions

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:

Perfect
Good
Average
Bad or No Data

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"
