The Main Beach surf guide

The Main Beach, located in the charming town of Hampton Beach, is a sand-bottom beachbreak that attracts surfers with its mellow vibe and decent waves. It’s generally less crowded compared to other spots, especially outside the summer months when tourists flood in. With no major bends or unique features in the coastline, though, it can get a bit messy when the swell picks up. The winter months can be tough here, with icy conditions alongside waves that can close out quickly.

Surfing at Main Beach really shines from late fall to early spring when the conditions align nicely. It can handle swell sizes between about 2 feet (0.6 meters) to 10 feet (3 meters) and picks up swells coming from the east, east-southeast, and southeast. The waves can break both right and left, making it a decent choice for all levels, from beginners to experts. During the right wind conditions, particularly from the southwest to northwest, the surf can be pretty fun. Tides also play a role, with low, mid, and high tides offering different opportunities depending on the day. Board options here vary widely, catering to shortboarders, funboarders, longboarders, fish riders, and bodyboarders alike.

Access to Main Beach is straightforward during the off-season, but if you’re planning to go in summer, it’s best to look elsewhere as surfing is generally frowned upon then. Crowds can be moderate, but the local vibe remains mellow, making it a great spot to relax and enjoy some time in the water. Just keep an eye out for clean-up sets, as they can sweep you unexpectedly closer to the seawall.

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.

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.

On the map, click a metric label to bring that arrow to the front — handy when arrows overlap.

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"
