Jocko's surf guide

Jocko's is named after the legendary North Shore surfer, Jock Sutherland. This spot is a left reef pointbreak located along the North Shore. Itโ€™s pretty easy to catch a wave here compared to some of the more famous spots up the coast, but don't get too comfy. When the WNW to NW swells roll in, Jocko's can deliver heavy barrels that challenge even experienced surfers. The spot is known for its relatively laid-back vibe, especially when compared to the hustle and bustle of nearby breaks.

The waves at Jocko's are best when swell sizes range from about 6 to 14 feet (1.8 to 4.3 meters) and come from the Northwest. You can expect steep take-offs that lead into solid left barrels, with the potential for some fast rides linking to an inside bowl section. The current can be pretty rough, especially on bigger days, so it's smart to watch for a while to figure out the take-off zone and where the channel is. The optimal wind directions are from the east, and all tide heights (low, mid, and high) work here, making it versatile for different conditions.

Access to Jocko's is straightforward; just park along Kam Highway where itโ€™s permitted, and the spot is visible from the road. It's usually crowded, but you'll still have a decent chance to score your own pit when the conditions are right. Most visitors here appreciate a friendly local vibe, and humility in the water goes a long way. Just be careful of the reef and rocks, particularly on the inside, and expect some cleanup sets on bigger days.

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.

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.

Log your surf sessions to compare forecasts with real sessions and sharpen future predictions.

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"
