La Grotte surf guide

La Grotte is tucked between Cape Blanc and Cape Bizerte. It's known for several left-hand reef options that work best when the conditions are right. This spot tends to favor clean waves, which makes it a popular choice for surfers looking to ride some decent swells.

The optimal swell direction at La Grotte is from the Northwest, but it can also handle swells coming from the West and Northeast. When it comes to size, the spot works well with swells around 2 ft (0.6 m) but can handle a bit more depending on the conditions. The waves break over boulders, creating fun left-handers that are perfect for intermediate surfers. If you’re planning your session, the best wind direction is coming from the South and it works well at all tide heights: low, mid, and high.

While La Grotte can get crowded at times, it's worth checking out for its consistent waves. Just keep in mind the swell size and wind conditions before heading out, so you can make the most of your time on the water.

Readme

Welcome! If you’re new to surf forecasting, check out this quick guide.

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"

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.
