Diamond Head surf guide

Diamond Head is a well-known surf spot in Hawaii, famous for its scenic views and consistent waves. Located near Honolulu, it features several breaks, with Lighthouse and Cliffs being the most popular. The area offers easy access down trails from Diamond Head Road, making it a go-to for surfers looking for a range of waves. The beach vibe here is chill, and crowds can vary throughout the day, with early weekends being the busiest.

The surf at Diamond Head works best with swells from the southeast to southwest, handling sizes between 5 to 10 feet (about 1.5 to 3 meters). The bottom is made up of reef, lava, rock, and coral. At Cliffs, you can expect smooth takeoffs and easier rides, while Lighthouse tends to offer a more high-performance experience with both right and left breaks. Keep in mind that currents can be tricky, and on larger swells, you might deal with cross currents, especially at Cliffs. Optimal conditions include low to mid tides and winds from the northwest to northeast.

The spot has a good local vibe, where surfers appreciate humility and respect out in the water. It’s a pretty pristine environment, so keep an eye out for reef hazards and ensure you're mindful of the local wildlife. Ideal for intermediate to expert surfers, Diamond Head can accommodate various board types, including shortboards, funboards, and kiteboards. The best season for surfing here is from spring through summer, particularly from April to October when the waves are more consistent.

Readme

Welcome! If you’re new to surf forecasting, check out this quick guide.

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.

Log your surf sessions to compare forecasts with real sessions and sharpen future predictions.

On the map, click a metric label to bring that arrow to the front — handy when arrows overlap.

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"

Wind certainty

Wind certainty tells you how much the weather models agree on the forecast.

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

We calculate this by comparing wind speed, gust and direction from multiple models (like GFS, ECMWF, Arome, and Harmonie) and seeing how closely they match. They are weighted, meaning that some models count more than others, depending on how good they are for a certain spot.
