Lavanono Left surf guide

Lavanono Left is a surf spot located in a remote village that has become quite popular among surfers looking for a more off-the-beaten-path experience. Most surfers travel from Fort-Dauphin to reach this spot, and they typically stay for a while to enjoy the waves. It’s a quieter place, meaning you’re likely to have plenty of space in the water. The vibe here is laid-back, and the local community has embraced surfers, making it a welcoming spot for those passing through.

The waves at Lavanono Left are primarily lefts breaking over dead coral. The best swell direction is from the Southwest, but it also handles swells from the Southeast. Overall, it can work well with swell sizes around 2 feet (approximately 0.6 meters). The wave tends to start with long, fast walls that may get a bit choppy due to side shore winds before bending into a hollow, offshore end bowl section. While the bowl can be shallow, it usually offers flat spots covered in kelp. It's generally better to surf here at all tide heights, but you might find some longer rights breaking inside the reef during smaller swells and low tides. This spot is suitable for intermediate surfers looking for some fun waves.

Beyond just the waves, Lavanono Left offers a unique surfing experience that’s tied closely to the local culture. The village kids often take turns riding shorter boards on the nearby reform left, and the locals keep an eye out, calling out warnings when sets come through. A local surf camp run by a Reunion-based surfer has also popped up, providing a place for tired surfers to relax after a day in the water. Overall, it’s a spot that combines decent waves with an authentic Malagasy experience.

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.

Log your surf sessions to compare forecasts with real sessions and sharpen future predictions.

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.
