Black Rocks surf guide

Black Rocks is a surf spot that attracts advanced surfers looking for some solid waves. It’s known for its somewhat reliable conditions, especially when you get the right swell and wind combination. It tends to be a little more consistent compared to nearby spots like Buffels, making it a go-to for those who know what they are doing out there. Expect a crowd, especially on the more popular right, as it’s a favorite among serious surfers.

This spot works best with a SouthEast swell and can handle swell sizes up to about 5 feet (1.5 meters). The waves break over uneven reef, which adds to the challenge. You’ll find both left and right breaks, giving you some options depending on your preference. For the best experience, a low to mid tide is preferable, and the winds from the west really help to shape up the surf.

Since Black Rocks is not for beginners, it’s important to be sure of your skills before hitting the waves. The layout can be tricky, and the reef can catch you off guard if you’re not paying attention. If you’re an expert looking for a new challenge, this spot could be worth checking out.

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"
