Rio Sierpe Rivermouth surf guide

Rio Sierpe Rivermouth is located near Drake’s Bay and can only be accessed by boat or a bit of travel on land. This spot is pretty remote, so you won't find many crowds here. The area is known for its natural beauty, but getting to the waves involves a bit of an adventure.

The surf is best during the incoming tide, where you can catch long, powerful lefts and rights. The ideal swell direction is from the Southwest, but it also works with swells coming from the South and Northwest. This spot can handle swell sizes from about 2 feet (0.6 meters) up, making it suitable for intermediate surfers. The waves break over sand, creating a rivermouth style that can be fun for those looking to mix up their sessions. Mid to high tides are preferable here, and when the wind comes from the east, conditions are generally better.

While you’re out there, keep in mind that the wildlife can be intense as this is a remote area. It's not uncommon to spot crocodiles and sharks in the vicinity, so always be aware of your surroundings. This spot can offer a different surfing experience compared to more popular locations, making it a unique option for adventurous surfers.

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"
