The Lowdown
Alright folks, Rusty here. Let's have a look at what's on offer for the coming stretch at Honokohau Harbour.
Right off the bat, I gotta be straight with you—the first week is a bit of a struggle. We're looking at some small, marginal waves and the early outlook isn't calling for anything to get too excited about. For the first few days, from September 9th through the 12th, we've got tiny swell—around 1ft to 3ft—and mostly cross-onshore winds making things choppy. The wave energy is weak, sitting under 350 (319). Water temp here is sitting at 82°, which is about a degree and a half warmer than usual for this time of year—nothing crazy, but nice for a quick session. The real standout in this whole window doesn't come until mid-month.
Let's talk about the real bright spot. Tuesday September 15th is the one to circle. That afternoon is looking clean and glassy with the wind going light. The swell is coming from the SW at 2ft, with a period around 19 seconds—that's a nice long-period groundswell that will wrap into this reef setup nicely. The wave energy is moderate at 380, enough to give it some push. This is a consistent break, so you can usually count on it, but with a swell like this, the shape should be there for the intermediate crew. Keep in mind it can get a bit crowded around here sometimes, so you might have some company. The swell direction is SW, which isn't a perfect match for the optimum WNW, but it's working.
Things stay quiet through the rest of the month, with a couple more promising glassy windows on the 17th (Thursday afternoon) and a few other moments. But honestly, nothing else really jumps out to compete with that Tuesday session. The second week's swell picks up a little in energy, hitting over 650 (658) around the 18th, but the wave heights stay small and conditions are just "marginal" for the most part. By the end of the window, from the 21st onward, it fades right back to almost nothing.
So, if you're keen, pencil in Tuesday September 15th afternoon. It's the best we've got.

Information about the Honokohau Harbour Surf forecast
The above surf forecast table for Honokohau Harbour provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Honokohau Harbour can be found by selecting the local surf guide option on the grey menu. Our Honokohau Harbour surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Honokohau Harbour) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Honokohau Harbour may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
