Ranch surf guide

The Ranch is a chill surf spot located by a reef across a wide, cliff-fringed bay. It's got two main passes and offers four different waves for surfers to enjoy. If you head to the north side, there's a decent left that works well when the swell is small and easterly. The main break is just across the pass, featuring a long, heavy right that barrels over the shallow reef. Depending on the conditions, you can catch rides that stretch up to 100 yards. On the south side of the peak, there's another left that kicks in when there’s more north in the swell, especially when the right starts to close out in spots.

The surf here can handle swell sizes from about 1.2 meters (4 ft) to 4.6 meters (15 ft). Tides can vary, but low to mid tides are usually preferred. The waves break over a reef, delivering some fun rides that cater to intermediate and expert surfers. When the winds come from the west or northwest, it typically creates a nice environment for catching waves. However, paddling can be pretty easy overall, yet it might get tricky with hurricane swells, so be prepared for that. Crowds are generally low key, making it a good spot to enjoy the surf without feeling overwhelmed.

The water here is nice and warm, typical of the Caribbean vibe. The best season for surfing at Ranch is from November to March and again in August to September. Just keep an eye out for the reef while you're out there; it can be a hazard, so stay alert. Overall, it's a solid big wave spot that’s best suited for advanced surfers.

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"

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.
