Belongas surf guide

Belongas is a relatively isolated surf spot that offers a unique experience for surfers looking to escape the crowds. Located in a remote area, it’s not the easiest place to get to, but it can be rewarding when conditions are right. It’s definitely a spot for those who like adventure and don’t mind a little extra travel to find some decent waves.

The surf here can be pretty fun when the SSW swell hits just right, especially with E or NE winds. You’ll find a decent left that works well at mid tide, suitable for intermediate surfers. The wave is a bit racy, featuring some tuck sections that keep things interesting. The right-hander across the bay also gets good but needs a lot of south swell and northwest winds during the wet season to be worthwhile. If you explore deeper into the bay, you might come across more options, including the Meang reef which can have some slower lefts and rights under the right wind and tide conditions.

Belongas handles swell sizes around 3 ft (about 1 meter) and prefers a swell direction from the South, Southeast, or Southwest. It's a reef break, so keep that in mind when paddling out. This spot can be a bit sharky, so always stay aware of your surroundings while you’re out there.

Readme

Welcome! If you’re new to surf forecasting, check out this quick guide.

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"

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.
