Coxos Surf Forecast Guide

Overview

Coxos is a powerful right-hand reef and pointbreak that peels along a series of rocky shelves and outcrops into a small bay on the Portuguese coast. Swells muscle in from deep water and unload onto the shallow lava reef, forming fast-moving, symmetrical walls that concentrate their power into the base of the wave rather than the lip, much like many Hawaiian waves. When it hits the slabs just right the ride is long, fast and hollow, and on its day it ranks among the best waves in the country.

When It Works

Coxos draws swell from southwest through north (SW-N), with northwest (NW) swell the best match. It works from 1.2 m / 4 ft to 3.7 m / 12 ft and can handle serious size when the swell is clean and from the northwest. Autumn and winter are the seasons to watch, and expect some real paddling on the bigger, better days.

Wind and Tide

Look for east (E) offshore wind, though the inside section can handle a light onshore. Low to mid tide suits the wave best, with a rising tide generally the better call — from just past low pushing towards mid is the window to aim for.

Local Tips

This is a wave for expert surfers only. There is no easy entry at Coxos: you have to paddle hard, get to your feet quickly and start driving, or you risk getting sucked over onto the reef. Getting in and out of the water is tricky, being caught inside is harrowing, the rips are brutal and urchins are common on the reef. A shortboard covers regular days, and a gun earns its place when it gets big. The lineup gets very busy, the takeoff zone is tight, and the locals know the spot inside out and can be protective of their diamond — the atmosphere stays friendly when you bring humility and respect.

Access

There is a dirt parking lot on the side of the hill, along with free roadside parking. You will also find camping, a surf school and a surf shop.

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 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.

🎯 Model agreement

The small letter in the wind and wave cells shows how closely the weather models we blend agree for that hour.

  • H, the models line up closely.
  • M, the models differ somewhat, so conditions may still shift.
  • L, the models disagree, so check again closer to your session.
  • A dash means only one model covered this hour, so there was nothing to compare.

For wind we compare each model's wind vector, plus gusts where every model reports them. For waves we compare height, period and direction of the matched swell systems.

It is a measure of model agreement, not a probability that the forecast is right.

🌒 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.

With Surfnerd, no more "you should have been here yesterday"
