Mainside surf guide

Mainside is a surf spot located at scenic Cape Zanpa, known for its unique waves and beautiful surroundings. This area attracts bodyboarders and surfers alike, thanks to its range of breaks. To access Mainside, you'll need to park at the lighthouse and take a bit of a walk, so be prepared for a trek before you hit the water.

The surf at Mainside is best with a north swell direction, although it can also work with northwest swells. It typically handles swell sizes from around 2 feet (0.6 meters) up. The waves break over live coral, creating both left and right reef breaks. For the best experience, it's advisable to surf around mid to high tide. The spot tends to favor east winds, making for cleaner conditions. However, this spot is definitely for experts, as the waves can be challenging.

Aside from the surfing, it's a great spot for taking in the views while you wait for your next set. Just keep in mind that this place can get crowded with experienced surfers looking to score those tubey rights. So, if you're up for a challenge and some quality waves, Mainside might just be the place for you.

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"
