Roca Puta Surf Forecast Guide

Overview

Roca Puta is an extremely dangerous right-hand reef on the east side of Orrua beach. It breaks over uneven reef and rocky boulders at the end of the headland, running beside a rock-lined sea wall.

This is a serious big-wave spot with a take-off dangerously close to the rocks, a critical first section, very strong rips, nasty rocks, and heavy wave power. It is for expert big-wave surfers only.

When It Works

Roca Puta needs a very large, clean swell and is not ridden many times a year. It works with swell from northwest to north, with north as the optimal swell direction.

The spot is usable from 1.2 m / 4 ft to 3.7 m / 12 ft. On swells over ten feet it becomes a serious proposition, and it begins to close out around 18โ€“20 foot.

Autumn is the main season, with the peak winter months also noted for the biggest, cleanest days.

Wind and Tide

The offshore wind direction is south.

A rising tide is better, and high tide is optimal.

Local Tips

Expect a busy, tight lineup when it is on, often with a strong local crew and spectators watching from the road. Humility and respect matter here, and inexperienced surfers are not tolerated.

Shortboards and guns fit the wave, but this is strictly an expert-only spot.

Water quality can get dirty after rain.

Access

Access is by a well-timed paddle off the rocks, with difficult entry and exit.

There is limited parking overlooking the break, plus free car-park and roadside parking, but it is normally packed when the wave is on. There are no beach facilities here.

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 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 chooses the "dominant wave" using spot-adjusted surf energy (depth + directional fit). This is usually the first swell partition, but during local storms it can switch to wind waves. If that happens, values are shown in gray and italic.

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"
