Playa Nosara surf guide

Playa Nosara is a long crescent-shaped beach with black sand, situated near the popular surf destination of Ostional. It attracts a lot of surfers, especially beginners and those looking for surf schools, making it a lively spot for learning to ride the waves. The scenery is nice, and the vibe is friendly, perfect for both new surfers and more experienced ones looking for a relaxed surf session.

The surf here is manageable, with wave heights ranging from about knee to head high (0.6 to 3.0 meters). It’s a good spot for beginners as the waves break over sand, making it a safer choice. The optimal swell direction is southwest, but it can also handle swells coming from the south and northwest. You can expect decent waves whether the swell size is around 2 feet (0.6 meters) or larger. The waves mainly come in both left and right directions, and the best conditions usually happen when the wind is coming from the northeast. You can surf at different tide heights—low, mid, or high—so it offers flexibility depending on the day.

In addition to its good surf conditions, Playa Nosara is well known for being beginner-friendly. Many surfers visit to improve their skills, thanks to the consistent and forgiving waves. The beach atmosphere is laid-back, making it a great place to chill after a surf session, reflect on your progress, or simply hang out with fellow surfers.

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"
