Castor surf guide

Surf at Castor, located at Zone 4 near Lanuza elementary school, is named after the landowner. This spot generally offers some good surf, especially at high tide. It's known for its rocky reef, which can be quite sharp and shallow, so surfers need to be cautious when paddling out. It's right in front of the Lanuza Surf Camp, making it accessible for those staying nearby.

Castor is recognized for its gnarly left-handed waves that break primarily over an uneven reef, but there are also some rights to consider. The best swell directions are from the North and Northeast, handling sizes around 2ft (0.6m) effectively. High tide is the sweet spot here, with South winds being ideal to keep the faces clean. This spot is generally recommended for expert surfers, as the waves can be challenging and require good skill to navigate.

When planning your surf session, keep in mind that this spot is further enhanced by its preferred wind conditions and tide heights. Make sure to check the swell forecast beforehand to catch it at its best. Overall, it’s a solid choice for experienced surfers looking for a bit of a challenge.

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"
