Matanuck surf guide

Matanuck is a popular surf spot located in Rhode Island, known for its variety of waves that cater to different skill levels. This place can get pretty crowded, given its reputation, and you'll often find surfers, kayakers, and even jetskis sharing the water. It's easily accessible with a year-round free parking lot, making it a convenient choice for both locals and visitors.

The surf here is quite diverse. Starting from the east, you'll find Deep Hole, which primarily offers fast and sectiony lefts, especially at low tide. Moving towards the center, Trestles has a nice shape with hollower rights and down-the-line lefts that work best on lower tides. Then there’s The Point on the west side—featuring a short, bowly right and a longer left that can connect to The Bar at higher tides for some extended rides. The spot handles swell sizes starting from about 2 ft (0.6 m) and can take on bigger waves, breaking over boulders and reef structures. Wind from the north tends to work best, and you can catch decent waves at low, mid, and high tide, although high tide may slow down the pace a bit.

Keep in mind that while Matanuck offers good waves, it can also be tricky. The rip currents can be strong, and paddling out gets tough when the swell picks up. Being aware of these factors will help you enjoy your surf session. So, if you're looking for a spot that has a bit of everything, Matanuck is worth checking out.

"Great Forecasts. Nothing more, nothing less."

Readme

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.

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. 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"

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.
