La Graviere surf forecast guide

La Gravière, located in the heart of Hossegor, is known for its powerful beachbreaks and is considered one of the top surfing spots globally. The area features a long stretch of golden sand that runs along the coast, providing ample room for surfers to carve up some waves. While it might get crowded, especially during the summer when the surf is more manageable, it’s a spot that attracts those looking for serious surf conditions later in the year.

The surf at La Gravière really shines with swells from the NW and W, producing waves that range from shoulder high (about 1 meter) to double overhead (over 3.5 meters). The wave types here include both right and left beach breaks, and they can get heavy and hollow, especially in autumn and winter. Paddling out can be a workout, particularly when the swell is pumping, so be ready for a bit of effort. The sand bottom can create some exciting barrels, but watch out for the infamous rip currents that can make things tricky. The waves here can handle sizes from 3 feet to 12 feet (1 meter to 4 meters), and you’ll want a shortboard to make the most of it.

Access to the spot is straightforward, which is nice, but expect a sizable local crew that is quite committed to their surf sessions. The crowds can get big, especially during peak times, which adds to the bustling vibe of the beach. Hazards do exist, with potential for serious wipeouts, so heed caution, especially for less experienced surfers. Best seasons for surf are from October to February, though you can find decent conditions year-round if you know when to go.

Readme

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

Forecast Table

The forecast table (the section on the page with all the numbers) is designed to pack as much information in the screen as possible. Although intimidating at first, it will help you make informed decisions about the waves faster, trust me :D. The table consists of roughly four sections, time and predictions, wind, waves, and tides:

🔮 Time and predictions section

Here we show the forecast thour and the overall surf quality prediction. This is determined based on the wave, wind and tide quality prediction. These individual predictions can be found on the forecast map.

💨 Wind section

The first row on the table (with the 💨 icon) shows wind speed, direction and gust. The more the wind speed the more aggressive the color (from blue, green, orange to red).

🌊 Wave section

The waves section consists of three rows, one for wave height and direction, one for period and one for wave energy. Our algorithm choices the "dominant wave". This is normally the first swell partition, but with heavy local storms it displays the wind waves. If that's the case, we display the numbers in italic and in gray.

🌒 Tide section

The tide section consists of a row with the actual heights per hour (measured at the half hour) and a table that displays the flow of the tide and the extremes (lows and highs).

Forecast map

The forecast map consists of arrows. These arrows represent all wave partitions (swell partitions and wind wave partition) and the wind. This allows you to see things like: a secondary swell or wind waves messes up the surf, or the wind is just a tick offshore so very surfable. Click a metric label in the bottom left to bring that arrow to the front — handy when arrows overlap.

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.

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"

Confidence

Confidence tells you how much the weather models agree on the forecast.

  • High confidence: Models agree closely; forecast is reliable.
  • Medium confidence: Some disagreement; conditions may shift slightly.
  • Low confidence: Models diverge; treat forecast with caution.

We calculate the wind confidence by comparing wind speed, gust and direction from multiple models (like GFS, ECMWF, Arome, and Harmonie) and seeing how closely they match. For wave certainty we compare height, period and direction, also on multiple models. They are weighted, meaning that some models count more than others, depending on how good they are for a certain spot.
