The Lowdown
Alright crew, Rusty here. Let’s chew the fat on what’s coming up.
It’s a quiet spell overall. We’ve got a steady little groundswell at Honokohau Harbour, but the wind’s been a bit of a pain for most of it. The energy levels are low to moderate, with the combined energy mostly in the low hundreds. The water temp is about normal for this time of year.
The pick of the bunch is Wednesday the 26th in the afternoon. The wind goes glassy, dead flat, and that’s a big deal. You’ll have 2ft waves from the SSW, with a very long 17 second period. That’s proper groundswell, and it’ll wrap nicely into the reef. The combined energy is 331 (moderate), so there’s a touch of power. It’s small, but it’ll be the cleanest you’ll find.
The rest of the time, it’s a struggle. Cross-onshore winds and rain showers keep things messy. Sunday the 23rd morning has a similar 2ft, 16 second swell, but the cross-on breeze kills the quality. From the 28th onward, it’s mostly tiny waves and poor wind, day after day.
There’s a long dry spell from the end of August into the first week of September. The waves are tiny, and the wind is nearly always cross-shore or cross-onshore. The only chance for a surf is the 6th of September afternoon, with 2ft from the SSW and an 18 second period, but even then it’s a gentle cross-shore breeze, so it’s only a maybe.
Bottom line: Wednesday afternoon is the one. Don’t miss it.
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.
