Raijua surf guide

Raijua is a remote and desolate island located between Sumba and Rote. It offers a unique surfing experience with its classic left-hand waves found on the SW tip of the island. This area is generally consistent and often goes uncrowded, making it a cool spot for surfers looking to escape the masses.

The surf here features some impressive lefts that can really crank up at lower tides. You can expect to catch fast and powerful waves, with some sections even offering barrels. The outside bombie adds a wild touch, especially during higher swells, and there's a steep, cliff-hugging wedge that can be a fun ride. The optimal swell direction is from the west, and it tends to handle swell sizes around 4ft (1.2m). If you're planning to surf here, it's best to aim for mid to low tides, and southeast winds work well to create decent conditions. Keep in mind that this spot suits intermediate surfers as the waves can get quite intense.

Since Raijua is not typically on the mainstream surf map, most of its waves are only surfed by passing charters. When the conditions align with the southwest to west swells, you can find some great rides here. Overall, it's a good idea to check the forecasts and tide charts before heading out to make the most of what Raijua has to offer.

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"
