Port O'Connor Jetties Surf Forecast Guide

Overview

Port O'Connor Jetties is a remote jetty setup off the Central Texas coast, with beach and jetty waves breaking over sand. The โ€œbig jettiesโ€ cut through the Matagorda Peninsula, and either side can work depending on swell and wind.

It can be fun on days with swell, but really comes to life when hurricane swell moves through the Gulf toward a landfall farther east. The jetties help reduce drift and can handle larger swells than many nearby spots.

When It Works

The spot works on east-southeast to south swell, with south and southeast swells especially noted for the sandbars. It is usable from 0.3 m / 1 ft to 1.8 m / 6 ft.

Spring and autumn are the main seasons, with late summer to fall and late winter to mid-spring also noted as productive windows.

Wind and Tide

The offshore wind direction is northwest. North, northwest, or west winds with swell are also a useful window here.

Low, mid, and high tide can all be in play, and a rising tide is better.

Local Tips

This is more suited to intermediate and expert surfers. Shortboards, funboards, longboards, and fish all make sense depending on the conditions.

Crowds are usually quiet to empty, though a few surfers may show up on major hurricane swells. The lineup can feel reserved.

Access

Access is difficult and requires a boat. The jetties are more than a 20-minute boat ride from town, and it is best to check the channel before looking for a safe place to land on the bay side of the island.

Bring sunscreen and water, and make sure the boat is securely anchored. The spot is isolated, and the pass outflow can still make the water dirty even though it feels far from the city.

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"
