J-Bay Surf Forecast Guide

Overview

J-Bay is a right-hand pointbreak, widely regarded as one of the longest and most perfect on the planet. It runs through a series of linked sections, Kitchen Windows, Magnatubes, Boneyards, Supertubes, Impossibles, Salad Bowls, Coins, Tubes, The Point and Albatross, with fingers of basalt holding the sand in place to create remarkably uniform bathymetry. When the swell is the right size and perfectly lined up, that setup can deliver rides close to a kilometre long between Boneyards and The Point.

When It Works

The point draws swell from southwest through southeast, with southwest the best match, breaking over boulders and sand. It works from 0.6 m / 2 ft to 3.7 m / 12 ft, and it is a consistent spot. Supertubes is the standout section and where the pro competitions run. Threading the multiple tube sections rewards speed and a high line, and cutting back is rarely a good idea.

Wind and Tide

Look for southwest offshore wind, which grooms most of the sections. Northwest to northeast Berg (or Devil) winds pour down off the mountains and blow straight into the barrels, throwing up a nasty chop that is hard to handle where speed is everything. It can work across low, mid and high tide, with a rising tide generally the better call.

Local Tips

This is an expert-level wave, where maintaining high speed and a high line is critical through the sections. That said, The Point and Albatross are slower, more manageable walls that suit intermediates and longboarders. Expect a very busy lineup when it is on, and Supertubes in particular draws the most competitive crew.

Access

Facilities include restrooms, showers, camping, a surf school and a surf shop, with free parking both in a lot and roadside. Currents can be unrelenting and sweep you down the point, so walking back up is part of the routine, then finding the keyhole through the sharp, mussel-coated boulders known locally as bricks. Booties and a strong board help you avoid damage and cope with cold, upwelling-fed water in the 15-19ยบC (59-66ยบF) range.

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.

๐ŸŽฏ 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.

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"
