Peahi - Jaws surf forecast guide

Peahi, commonly known as Jaws, is a legendary surf spot located on the north shore of Maui. It's famous for its massive waves and is considered one of the most challenging locations in the surfing world. While it draws experienced surfers and spectators alike when a significant swell hits, the reality is that most surfers will likely never ride these extreme waves due to their sheer size and powerful nature.

The waves at Jaws primarily handle swells from the Northwest and Northeast, with the ideal swell size starting at around 12 feet (approximately 3.6 meters). Surfers can expect both lefts and rights breaking over an uneven reef, making it crucial for those who want to surf here to have expert-level skills. The best conditions are often found with a southeast wind and can work during low, mid, or high tides, but everything comes with risks due to the powerful impact zone and heavy chop. The waves at Jaws can deliver some incredible, house-sized right tubes, but not everything here is perfect – it can be unpredictable, and you'll want to know what you're doing before paddling out.

If you’re not planning to surf, the best way to enjoy Jaws is to find a good spot on the cliffs with a parking area on the western headland. Grab some binoculars or a camera with a long lens, and you'll have a front-row seat to witness the skill and bravery of the surfers taking on this beast of a wave. Just remember that this is for expert surfers only, and it’s not a place for the casual paddle-out.

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.

Welcome! If you’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:

🔮 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.

💨 Wind section

The first row on the table (with the 💨 icon) shows wind speed, direction and gust. The more the wind speed the more aggressive the color (from blue, green, orange to red).

🌊 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.

🌒 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 — handy when arrows overlap.

Forecast Cheat Sheet

Short on time? Focus on wave energy. It’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. Here’s the scale:

Perfect
Good
Average
Bad or No Data

Session logs also feed the algorithm — the more you log, the smarter your forecasts get.

With Surfnerd, no more "you should have been here yesterday"
