Laniakea Surf Forecast Guide

Overview

Laniakea, known locally as Lani's, is a broad right-breaking reef about two and a half miles north of Haleiwa on Oahu's North Shore. The main takeoff sits roughly 400 yards offshore, over one half of a massive lava hammerhead; the other half forms the left known as Jocko's, a quarter-mile to the northeast. A channel running out beside the point cuts partway through the reef, giving a fast paddler a way across the thinnest section between closeouts. On its day it ranks among the North Shore's finest waves, a long ride that offers a bit of everything.

When It Works

Laniakea draws swell from west through north to northeast (W-N-NE), and northeast (NE) is the direction to look for. The more northerly angled swells wrap down the line in long, bowling sections, and a straight north swell brings out the best of the wave: outrageously fast, with hollow, cylindrical sections, especially on the inside wedge. On most winter days it breaks smaller northwest swells into a series of more manageable peaks. It works from 0.9 m / 3 ft to 3 m / 10 ft, holding size from head high to a couple of feet overhead. Consistency is only medium, so it can be inconsistent, but the windows are worth waiting for. The season runs autumn through spring, with winter the prime time. Some lefts show up on west swells as the lineup breaks up, though going against the grain means paying a price over the reef.

Wind and Tide

Look for an east (E) offshore wind; the workable wind window runs from calm through light to moderate ENE to S. It can work across most of the tide, from low through high, with a rising tide generally the better call.

Local Tips

This is an intermediate wave that suits everything from shortboards and fish to longboards, bodyboards, and SUPs. Expect a busy lineup when it turns on, though the crowd tends to spread out across the peaks, and the atmosphere is somewhat reserved. Wide-swinging sets can pick you off and send you back to the paddle-out point, and shallow spots on the inside reef demand attention. Watch for strong currents, especially on big north swells when a rip swings off the end of the break to the west, and stay mindful of the reef and occasional shark sightings.

Access

Getting in is easy. Park in the dirt lot on the inland side of Kam Highway, just across from Laniakea beach.

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 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.

๐ŸŽฏ 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.

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.

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"
