Riomar Reef surf guide

Riomar Reef is a surf spot located a bit off the beaten path, mainly surfed by a few locals in the know. It’s somewhat remote, requiring a bit of effort to access, and you won’t find much in terms of parking unless you’re a local resident. The spot offers a mixed bag when it comes to waves, with the inside breaks being less impressive compared to other shorepounds in Vero. However, when the conditions align, it can provide a unique experience for those willing to put in the time.

The optimal conditions here include a strong North swell, particularly between 2ft (0.6m) to 10ft (3m), with low tide often being the best time to go. When the outer reef is firing, typically over rock/reef, both left and right waves can produce some decent rides. The best wind directions are from the west, and although it can handle swell from the NorthEast as well, it really thrives when the stronger swells come in, especially during hurricane season. For the more experienced surfers, this spot can be an enjoyable challenge, but it's not suitable for beginners. When it’s small, the better option might be nearby spots.

Even though there aren’t many crowds, you should still approach with caution as this area is known to have bull sharks. The vibe is generally pretty chill among the locals, making it a laid-back place to catch some waves—provided you know what you're doing. Just keep an eye on the conditions, and if anything feels off, it might be best to take a break. The surf season here runs mostly through the fall, winter, and spring, so if you're looking to ride at Riomar Reef, that's the best time to head out.

"Great Forecasts. Nothing more, nothing less."
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.

Readme

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

Forecast Table

The forecast table (the section on the page with all the numbers) is designed to pack as much information in the screen as possible. Although intimidating at first, it will help you make informed decisions about the waves faster, trust me :D. The table consists of roughly four sections, time and predictions, wind, waves, and tides:

🔮 Time and predictions section

Here we show the forecast thour and the overall surf quality prediction. This is determined based on the wave, wind and tide quality prediction. These individual predictions can be found on the forecast map.

💨 Wind section

The first row on the table (with the 💨 icon) shows wind speed, direction and gust. The more the wind speed the more aggressive the color (from blue, green, orange to red).

🌊 Wave section

The waves section consists of three rows, one for wave height and direction, one for period and one for wave energy. Our algorithm choices the "dominant wave". This is normally the first swell partition, but with heavy local storms it displays the wind waves. If that's the case, we display the numbers in italic and in gray.

🌒 Tide section

The tide section consists of a row with the actual heights per hour (measured at the half hour) and a table that displays the flow of the tide and the extremes (lows and highs).

Forecast map

The forecast map consists of arrows. These arrows represent all wave partitions (swell partitions and wind wave partition) and the wind. This allows you to see things like: a secondary swell or wind waves messes up the surf, or the wind is just a tick offshore so very surfable. Click a metric label in the bottom left to bring that arrow to the front — handy when arrows overlap.

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.

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"
