Piedras Blancas surf guide

Piedras Blancas is located just north of downtown San Simeon. Accessible via Highway 1, this surf spot features a mix of beach and reef breaks that can deliver varied conditions. The area is known for its mix of surfers, from beginners to more experienced riders. The scenery is nice, with the backdrop of coastal cliffs and the infamous elephant seals that hang around nearby.

The surf here can range from a thick right-hand reef break during clean conditions to a peaky, rocky beach break on smaller days. It generally handles swells from 4ft to 8ft (1.2m to 2.4m) well, with preferable swell directions being south, southwest, and west-northwest. The waves break over a combination of sand and rock, with rights being more common, though there are lefts to be found too. Ideal conditions usually require a low to mid tide and winds from the northeast to east, making for a somewhat reliable session when the swell is in the chest-high to overhead range (around 1.2m to 2.4m). Intermediate and expert surfers will find it more enjoyable, especially during summer and winter months.

Access to Piedras Blancas is straightforward. Park at the tiny cul-de-sac on Pico Avenue and take the staircase down to the beach. Crowds can be moderate, with around 10-15 surfers being a typical occupancy, so it's good to be chill and respectful to the locals. Keep in mind that the local vibe is present, partly due to the elephant seals and even some invisible white sharks in the area. It's best to be aware of your surroundings while enjoying the surf.

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.

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"

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.
