San Clemente State Park surf guide

San Clemente State Park is a popular surfing spot located about half a mile up the coast from the Trestles area, providing a nice escape from the hustle and bustle at Lowers. It's pretty accessible, with a parking lot at the foot of Avenue Calafia, making it easy to get in the water. The beach break here has a decent but not overpowering lineup, so you can often find a wave to ride without battling for space. This spot is known for its mellow vibe, which stands in contrast to the more intense scene at nearby breaks.

The surf here offers both lefts and rights, primarily breaking over a sandy bottom. It handles swell sizes from about 3ft (0.9m) to 8ft (2.4m), making it suitable for various skill levels from beginners to more experienced surfers. Summer and autumn are the best times to catch some fun waves, especially with southwest swells rolling in. For the most part, the waves are pretty sectiony, so keep an eye out for those good moments. The optimal swell directions are south and northwest, and you'll want to aim for the periods of low to mid tide to get the best conditions. Winds from the northeast are preferable for a cleaner ride.

Access to the spot is straightforward, with direct access from the parking lot where you'll find bathrooms for convenience. When it comes to board types, you can use anything from shortboards and fish to funboards, longboards, and even bodyboards. You'll find that the crowd factor is manageable, so you can enjoy your surf without the chaos typical of more popular spots like Trestles. Just watch out for groms and the occasional mid-morning onshore breeze that can chop things up a bit.

Readme

Welcome! If youโ€™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:

๐Ÿ”ฎ 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.

๐Ÿ’จ Wind section

The first row on the table (with the ๐Ÿ’จ icon) shows wind speed, direction and gust. The more the wind speed the more aggressive the color (from blue, green, orange to red).

๐ŸŒŠ 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.

๐ŸŒ’ 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 โ€” handy when arrows overlap.

Forecast Cheat Sheet

Short on time? Focus on wave energy. Itโ€™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. Hereโ€™s the scale:

Perfect
Good
Average
Bad or No Data

Session logs also feed the algorithm โ€” 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.
