North Bar surf guide

North Bar is a surf spot located on the north side of Montauk Point in Long Island, New York. This place offers surfers a chance to catch waves in a medium-consistency environment. It's a popular spot, especially when conditions are favorable, so expect a bit of crowding during those times. The area is pretty scenic but do keep in mind that parking at Montauk Point State Park comes with a fee, except during winter weekdays. You'll find some nice heated restrooms here to change into your wetsuit comfortably.

The surf at North Bar works best with an East swell or a solid Southeast swell that wraps around the point. It tends to be a good option when other spots are blown out, thanks to the offshore winds from the southwest. The waves mainly break to the right over a mix of boulders and sand, and they can handle swell sizes from about 2 feet (0.6 meters) and up. Most surfers here are at an intermediate level and can look forward to fast, down-the-line sections, though the waves donโ€™t really get hollow or link up well. A low, mid, or high tide is suitable for riding there.

Although the variety of conditions can be appealing, be prepared for the currents to get strong, which is typical for Long Island surf breaks. Always keep an eye out for jellyfish in the summer months. Knowing the local behavior of the waves and the currents can definitely make your session more enjoyable.

"Great Forecasts. Nothing more, nothing less."
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"
