The Lowdown
Alright crew, Rusty here, checking the charts for Honokohau Harbour.
Honestly, the first part of this run is a slow one. A lot of days with tiny, weak surf and the wind coming from the wrong direction. It’s not looking like much fun for a while.
The one day that really stands out, and the one you should be aiming for, is Monday morning, September 7th. We’ve got a 4ft SSW swell with a super long 17 second period. That’s real groundswell energy, and the combined energy is sitting at 925 (moderate), which is the best we’ll see. The wind is a light offshore from the WNW, meaning the surface will be glassy and clean. For a reef break like this, that long period is going to make for some nice, lined-up waves. Don’t sleep on this one.
The 8th also has some push in the afternoon, with a 5ft SSW swell and 14 second period, hitting 1160 (moderate) on the energy scale. But the wind is cross-on, so it’ll be a bit messier. Still worth a look if you miss the 7th.
After the 10th, the surf really drops out. We’re talking tiny waves, around 2ft or less, and the wind isn’t helping. The 15th of September afternoon goes glassy, but the swell is only 1ft – not much to work with there.
Water temp is about normal for the season, so no shocks there. And Honokohau Harbour can see a few heads in the water sometimes, so don’t expect it to be empty.
Bottom line: mark the 7th of September. That’s the session to aim for.
Rusty.

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.
