La Boca surf guide

La Boca is a surf spot located near the mouth of the Aconcagua River. This area features a wide beach that has become a go-to destination for beginners and surf schools. It’s well-protected from south winds, making it a relatively pleasant spot for a session. The beach can have decent surf conditions if the sand aligns just right, but expectations should be tempered as it can often be inconsistent.

The surf here generally favors south and west swells, with optimal conditions when the swell is around 2ft (0.6 meters). The waves break over sandy bottoms and come in both left and right directions, making it beginner-friendly. It’s best to hit the water during low to mid tides for better chances at catching rideable waves. If the conditions are small, heading north towards Punta del Piedra can still yield some fun opportunities.

While La Boca is a spot that attracts a crowd of bodyboarders and beginners, it’s always good to be aware of the surf environment. This beach is known for having a lively atmosphere, particularly with those just starting out. If you’re looking for more mellow setups, you can check out Playas Amarillo and Negra around the corner, where you might find easier conditions on those busy town beaches.

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.
