La Islilla (Piura) surf guide

La Islilla is a small fishing village in Piura, Peru, that’s known for its laid-back vibe and picturesque scenery. The spot isn’t exactly buzzing with tourists, which means it can offer some peace and quiet for surfers looking to catch some waves. The village life is simple, and local kids often ride the waves using wooden boards made from old fishing boats. The surf scene here is pretty low-key, making it a nice escape for those who want to surf without all the crowds.

When it comes to surfing at La Islilla, the main wave setup features a right-hand point break that works best with a southwest swell. The surf can get hollow, especially during summer swells coming from the north and the east winds. This spot tends to break over uneven reef and can handle swell sizes starting at about 2 ft (0.6 m). The wave is generally suited for intermediate surfers looking to ride a mixture of right point breaks and some decent beachbreak peaks north of town. However, keep in mind that the consistency is just low to medium, so don't expect it to be firing often.

For the best conditions, aim for low to mid or even high tide, as the waves tend to perform better during these times. There are not many surfers out here due to the erratic nature of the breaks, which gives you plenty of space when the waves do come in. Remember, if you’re hoping to score some epic sessions, it might take a bit of patience since the waves can be hit or miss. Overall, La Islilla offers a chill experience for surfers looking for something different.

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.

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"

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.
