The Lowdown
Alright crew, Rusty here. Let's cut to the chase – Honokohau Harbour is looking pretty flat for a while, so don't go getting your hopes up.
The run starts on Thursday, August 27th, and for the first week and a half it's nothing but "poor surf conditions." We're talking tiny swell, mostly between 1ft and 3ft, with cross-onshore breezes ruining any chance of clean waves. The water's sitting at 82°, which is a touch warmer than normal for this time of year, but that's the only highlight. From Thursday the 27th all the way through to Monday the 7th of September, it's pretty much a dead zone. The combined wave energy is barely registering in spots (27 to 93), just weak little windswells not worth paddling for.
Around the 7th of September we get a little pulse. Monday the 7th morning shows a 3ft SSW swell with combined energy of 349, but it's still "marginal" and the wind is cross-onshore. Not exactly a green light.
The one period that's the best on offer – and I'm being honest here – is the morning of Tuesday the 8th of September. We've got a 4ft SSW swell with combined energy of 726, and offshore wind from the West. That means clean conditions for this reef break that's fairly exposed to WNW swell. The swell period is a solid 16 seconds, so there's proper groundswell energy, though it might run a bit straight on the outside. It's for the intermediate crowd – 4ft is fun, not huge.
After that, the afternoon of Wednesday the 9th of September gives us a brief glassy window with a 3ft SSW swell and combined energy of 331. "Expect good surf conditions" it says, but it's still a small wave. Could be a fun log session.
Bottom line: if you're keen, aim for Tuesday the 8th of September morning for the cleanest, most energetic swell of the whole run. The rest is either flat, choppy, or too weak to bother with. This is a quiet stretch for Honokohau Harbour, so don't stress it.
Rusty.

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.
