Seabrook Beach surf guide

Seabrook Beach is the last stop in New Hampshire for surfers looking to catch some waves. This beach offers a mix of sandbars and peaks that can provide decent surf along its entire stretch. While parking can be a hassle in the summer, the beach isn't overly crowded, making it a pretty chill spot to hit the water. Just keep in mind, there are signs around that say no surfing, so be aware of local regulations.

The surf here can be quite variable. Beachbreak peaks work with swells from the East, ESE, and Southeast and can handle sizes from about 2 feet (0.6 meters) to 10 feet (3 meters). The waves can be fun with good shape, especially on a nice day with the right wind from the west. Youโ€™ll find left and right waves, which can be great for intermediate and expert surfers. However, it can get tricky to paddle out when the swell is pumping, especially in winter when youโ€™ll need to gear up in full wetsuits due to the freezing temperatures. The tide plays a big role in how the waves break, so pay close attention to that as you plan your session. The beach breaks over sand, so it can either deliver powerful hollow waves or slower, mushy shoulders depending on conditions.

Seabrook is best surfed between September and March, making it a solid autumn and winter spot. The crowd factor is low, giving you plenty of room to maneuver out there. Just be prepared for tougher paddling conditions in the winter, while summertime is usually more mellow. If you're all about surfing on a shortboard or funboard, Seabrook Beach can be a decent pick, especially if you catch it on a good day.

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"

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.
