Indicators surf guide

Just down the beach from Domes and near the Lighthouse, you'll find Indicators. It's named after the rock in the middle of the lineup, which serves as a cue for sets heading towards The Point and Maria's. This spot can get tricky when it's on, so you need to be ready. To catch a wave, youโ€™ll want to take off almost directly in front of that rock. If youโ€™re feeling brave, you might even want to take on the Deadman's peak right in front of it. As you ride the wave, youโ€™ll notice it starts to get better right around the rock, especially when the tide is high. The rock does help spread the crowd out a bit, so it's not too overcrowded, which is a plus.

When it comes to the waves at Indicators, you're looking at head-high to double overhead swells (about 1.2 to 2.4 meters). It handles swells from 4ft to 8ft (1.2 to 2.4 meters) and works best with NW, N, or even NNW swells. The wave type here is a mix of reef and point, breaking to the right. Youโ€™ll want the wind coming from the NNE, NE, ENE, E, or even SE for the best conditions. Generally, lower tides are better, specifically low to mid. Keep in mind, the paddle out can be a workout, depending on the swell.

As for access, you can park just before the lighthouse and make your way through the brush to get to the spot. Donโ€™t expect a bustling crowd; youโ€™ll mainly see a few locals, and the vibe is pretty chill. The best time to hit up Indicators is during late summer and fall for the tropical cyclone swells, or from late fall through early spring for some consistency. Itโ€™s a solid alternative to Mariaโ€™s when the conditions are right, and it works well for both shortboards and bodyboards, but youโ€™ll need to have some experience to handle this break.

Confidence

Confidence tells you how much the weather models agree on the forecast.

  • High confidence: Models agree closely; forecast is reliable.
  • Medium confidence: Some disagreement; conditions may shift slightly.
  • Low confidence: Models diverge; treat forecast with caution.

We calculate the wind confidence by comparing wind speed, gust and direction from multiple models (like GFS, ECMWF, Arome, and Harmonie) and seeing how closely they match. For wave certainty we compare height, period and direction, also on multiple models. They are weighted, meaning that some models count more than others, depending on how good they are for a certain spot.

Readme

Welcome! If youโ€™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:

๐Ÿ”ฎ 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.

๐Ÿ’จ Wind section

The first row on the table (with the ๐Ÿ’จ icon) shows wind speed, direction and gust. The more the wind speed the more aggressive the color (from blue, green, orange to red).

๐ŸŒŠ 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.

๐ŸŒ’ 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 โ€” handy when arrows overlap.

Forecast Cheat Sheet

Short on time? Focus on wave energy. Itโ€™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. Hereโ€™s the scale:

Perfect
Good
Average
Bad or No Data

Session logs also feed the algorithm โ€” the more you log, the smarter your forecasts get.

With Surfnerd, no more "you should have been here yesterday"
