Playa Hermosa South surf guide

Playa Hermosa South is known as one of the more consistent beach breaks in Costa Rica. It features about four miles of stunning black sand and has a pretty deep offshore area. This spot picks up swell from various directions, including the South, South-Southwest, and West. While it can get pretty crowded at the best peaks, there's plenty of room to find your own wave along its stretch. Access is straightforward, just a two-hour drive from the airport, with parking available near several local spots.

The surf here can range in size from about 5 to 9 feet (1.5 to 2.7 meters) and is best for intermediate and expert surfers. The waves tend to break over sand, forming lefts and rights that can get fun. The beach is most favorable during mid to high tide, and when the swells are firing, it can be quite powerful. On solid south swells, you may encounter heavy A-frames that offer challenging rides. Keep in mind that once the size goes beyond double overhead, it can often close out, leading to some tough paddling and possible board breaks.

The wind typically blows in from the northeast, which is ideal for optimal conditions. Surfers often use shortboards, fish, or guns depending on the swell and their own skill level. While the north end of Playa Hermosa has the best sandbanks, moving south toward Tulin, there's a popular sandbar that works well on lower tides with more exposure to west swells. It’s a good idea to be aware of your surroundings and respect the local vibe, as it can be a bit intense sometimes.

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.

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.

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"
