Pipeline & Backdoor surf guide

Pipeline & Backdoor is one of the most famous surf spots in the world, located on the North Shore of Oahu. It's known for its stunning waves and lively surfing scene. The spot explodes off a rocky, uneven reef about 80 meters offshore, attracting surfers from all over. While it can offer some incredible rides, itโ€™s not always a guaranteed swell. During summer months, the waves can disappear, and you wouldn't even know it's there unless youโ€™re in the know. When the right swell hits, though, Pipeline comes alive and draws in surfers looking to test their skills.

Pipeline works best with a WNW to NW swell and is known to handle sizes from 1 meter (3 feet) all the way up to 4.5 meters (15 feet). The left at Pipe provides a hollow, barreling wave, while Backdoor, the right, offers a different experience but can be equally as challenging. The waves usually break over a reef, demanding skill and respect. The best tide to surf is usually around low, mid, or high, and conditions are optimal with light E to SE winds. Make sure you're aware that this spot is for experts only, as it requires a good understanding of reef breaks and the local vibes, which can get pretty intense.

Access is pretty straightforward with Ehukai Beach Park right there offering parking, but be ready for heavy crowds when the surf is firing. The dynamic of the place changes quickly, and having humility and respect for the locals is a must. Surfboards like shortboards, bodyboards, and guns are preferred here. Keep in mind that when conditions arenโ€™t ideal, like when sand builds up, Pipeline can turn into a gnarly closeout, so timing your visits is key. This spot truly showcases the raw power of nature and is definitely a must-ride for serious surfers.

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 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.

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"
