Ghallis Rock surf guide

Ghallis Rock is a popular surf spot, especially for those into windsurfing and surfing. It's located on an exposed outer reef, which means the waves can be pretty intense. The spot is known for its shallow and fast lefts that can be a bit tricky to navigate, making it more suitable for intermediate surfers. The area is generally scenic, offering a great view while you're out in the water.

The optimal swell direction here is from the NorthEast, with the spot also handling swell from the East. Ghallis Rock is capable of waves around 3ft (0.9 meters), which is a decent size for surf enthusiasts. The waves break over an uneven reef, so keep that in mind when you’re out there. If you're looking for the best conditions, aim for a SouthWest wind and surf during low to mid or high tide for optimal results. Just be aware, this spot is best suited for intermediates due to the challenging wave conditions.

Getting in and out of the water can be the main hassle at Ghallis Rock. To paddle out, you'll want to jump off the old concrete platform. When you’re ready to come back in, you’ll need to scramble the rocks right in front of the island, so a bit of caution is advised. Enjoy your time out there!

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"
