Santa Cruz surf guide

Santa Cruz is a well-known surf spot that offers a mix of beach breaks and some interesting features for surfers. It's popular among both locals and visitors, and while it might not be as famous as Steamer Lane, it has its own charm. The beach stretches for quite a distance, and it’s home to some powerful waves and a fun atmosphere, especially in the summer months. You'll find parking along the clifftop, making access pretty easy for those wanting to hit the waves.

The surf here can handle a wide range of swell sizes, from about 1.5 meters to 3.6 meters (5ft to 12ft). The best conditions typically come from the SouthWest, WestSouthWest, and West directions, and you'll find the waves breaking over sand and some rocky spots. The beach offers both right and left waves, making it suitable for different styles of surfing. Early mornings or days when the wind is from the NorthEast to EastSouthEast can be ideal. The tides usually work well here at low to mid or mid to high, catering to all skill levels—whether you’re a beginner or an expert looking for a solid ride.

While the main peaks can get crowded, especially close to town, taking a short walk can help you find quieter spots if that’s what you’re looking for. The waves can pack a punch and you'll need to be ready for some strong currents and rip tides, particularly when it's big. Autumn is generally the best time to surf here, especially from September to November when the conditions can be pretty clean. Don't forget to bring your shortboard, funboard, or even a longboard, depending on what you're into!

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"

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.
