Castricum surf forecast guide

Castricum is a mellow surf spot on the Dutch coast that works well for a relaxed session when the conditions line up. It’s not a world-class wave, but it has its moments—especially for those just starting out or looking to get a few easy rides in without too much hassle.

The waves here break over a sandy bottom, making it a forgiving place to learn or improve. Swell needs to come from the northern half of the compass, with NorthWest being the most reliable direction. Castricum can start working from around 0.3 meters (1 foot) and holds up to about 1.5 meters (4.9 feet), which means it’s rarely too intimidating. Both lefts and rights show up, depending on the banks and the angle of the swell. The beach setup means the wave shapes can change frequently, but there’s usually something to work with when the swell is right.

Wind is a key factor here. You’ll want winds from the ESE to keep things clean, though anything with an easterly component can help. Onshore winds—especially from the west—can quickly ruin it. The tide also plays a big role. It works best around mid-tide, ideally on the push. High tide can still be okay, but low tide tends to expose too much sand and flatten things out.

This spot is beginner- and intermediate-friendly, so you won’t feel out of place if you’re still figuring things out. Just keep an eye on the tides and wind before heading out.

Getting to Castricum is easy. There’s decent access to the beach, and it’s a popular area, so you’ll find parking and basic amenities nearby. Just bring your gear and check the conditions before you go.

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.

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.
