The LineUp at Wai Kai Surf Forecast Guide

The LineUp at Wai Kai is built around the Wai Kai Wave, a 100-foot-wide deep-water standing wave in the Wai Kai community of Ewa Beach. Created by citywave in partnership with Shane Beschen and run by Surf Park Management, it is as much a social hub as a surf spot, with a 52-acre recreational lagoon, a restaurant, a café, and retail sitting alongside the wave. The pool is well managed and the water clean, and it draws everyone from first-timers to competitors.

When It Works

Being a surf park, it runs year-round, and there is no paddle out to deal with. The wave is endless and fully adjustable, holding glassy shape anywhere from two feet up to head-high, so it suits every skill level on a standard board with fins. There is plenty of room to carve and surf top to bottom, and it peels both left and right over the rock base. It is a genuinely fun wave, great for progression and a serious workout in its own right.

Wind and Tide

The wave works best at high tide, with a rising tide the better call.

Local Tips

The lineup pulls a good mix of beginners, intermediates, and experts, and works for shortboards, fish, funboards, bodyboards, and bodysurfing. Expect a moderately busy lineup that can feel a little reserved; it is lightest on weekdays and picks up through the afternoon and on weekends, with the more advanced crew often turning up in the evening. The surf ops team is quick to help everyone get comfortable with the wave. It pays to ride the boards provided rather than bring your own, and to wear the helmet on offer, since boards can shoot back quickly after a bail.

Access

You will find it in Ewa Beach, about 22 miles from Honolulu. There is a big parking lot, plus two bars, two restaurants, and a range of other activities to round out the day.

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 chooses the "dominant wave" using spot-adjusted surf energy (depth + directional fit). This is usually the first swell partition, but during local storms it can switch to wind waves. If that happens, values are shown in gray and italic.

🎯 Model agreement

The small letter in the wind and wave cells shows how closely the weather models we blend agree for that hour.

  • H, the models line up closely.
  • M, the models differ somewhat, so conditions may still shift.
  • L, the models disagree, so check again closer to your session.
  • A dash means only one model covered this hour, so there was nothing to compare.

For wind we compare each model's wind vector, plus gusts where every model reports them. For waves we compare height, period and direction of the matched swell systems.

It is a measure of model agreement, not a probability that the forecast is right.

🌒 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"
