Mundaka surf guide

Mundaka is a well-known surf spot located at the mouth of a river in the Basque Country, Spain. It's famous for its left-hand waves and has a reputation as one of the best rivermouth breaks in the world. This small fishing village offers a unique combination of stunning scenery and challenging surf conditions. The town can get busy, especially when the waves are firing, but it holds onto a bit of that classic village charm.

The wave at Mundaka is shaped by the river and oceanic currents, creating a nearly perfect sandbank. With swells coming from the northwest, the wave can handle sizes from 6ft to 12ft (about 2 to 4 meters). When it’s on, expect long rides, with barrels reaching up to 200 yards (around 180 meters). The wave can be tricky to navigate, with steep, pitching take-offs that can be challenging, especially for those not at an expert level. It's best to surf during autumn and winter, with low to mid-tide being the sweet spot. The preferred wind direction is southwest. Watch for the rip that helps you get back to the peak after your ride.

Accessing the surf can be a bit complicated due to the narrow streets in Mundaka, but if you find a parking spot near the church overlooking the break, you’re in luck. The vibe in the water can be intense, with crowds reaching up to 100 surfers on the best days. Surfing here can be competitive, so if you sit farther down the point, you might snag a few good scraps. Overall, Mundaka is a world-class surf destination, but it requires skill and patience, especially with the locals around.

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.

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.

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"
