The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Honokohau Harbour.
To be straight with you, the next 16 days are looking pretty bleak for a proper paddle. The swell energy is almost entirely weak to moderate, with combined energy values mostly under 300, and the wind and conditions rarely line up. There’s a small window of glassy surf on the morning of Tuesday, August 25th, but the swell is tiny at 2 ft from the SSW. That said, the glassy wind (6 mph from the WSW) will make it look pretty as a picture. The water temperature is sitting at 82°, which is a touch warmer than normal for this time of year.
After that, we hit a long, frustrating gap. From Tuesday afternoon all the way through to the start of September, nearly every session is marked as poor surf conditions. Winds are mostly cross-onshore or onshore, and the swell stays small and messy. There’s a brief uptick in energy around the morning of September 1st, where the combined swell energy jumps to 534, but the wind is onshore from the west at 6 mph, the break is described as marginal, and the swell height is only 3 ft. Not worth paddling out for.
The next real spike in energy comes on September 5th and 6th, with combined energy values hitting 528, 673, and even 807. That’s moderate to strong energy, and the swell direction is from the SSW with a long period up to 20 seconds. That’s proper groundswell. But the catch is that the wind is cross-onshore or onshore for most of those sessions, and the comments still call it marginal at best. For a reef break, that long-period swell could actually be quite special if the wind cooperates, but the forecast keeps it dirty. The swell heights are still only 3 ft to 3 ft, so nothing huge.
Honestly, there’s no standout session here. The morning of August 25th is the cleanest surf, but it’s small. If you’re desperate for a glassy, knee-high wave and no one else around, that’s your moment. Otherwise, this is one of those quiet stretches where you’re better off waiting for the next South Pacific pulse to line up with some offshore wind.
Rusty.

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.
