The Lowdown
Alright folks, Rusty here. Let's have a look at what's cooking for the next couple of weeks.
Honestly, it's a pretty quiet stretch ahead. We're looking at a long run of very small surf, with a lot of poor conditions in the mix. The first real chance of anything surfable doesn't show up until late in the window, so be prepared for a lot of flat days.
The one spot we've got to talk about is Honokohau Harbour. This is a consistent reef break that's fairly exposed to the swell, and it likes the swell coming from the west-northwest. The water temp is sitting right around 82°, which is a touch warmer than usual for this time of year.
For the first week and a half, it's a real struggle. From Saturday the 22nd of August right through to around Monday the 31st of August, the swell is tiny – mostly 1ft to 3ft. The combined wave energy is weak, hanging in the low 100s to mid-300s, which is just not enough to get anything decent going. The wind is mostly onshore or cross-onshore, and the forecasts are calling it either "poor surf conditions" or "marginal" at best. There's a bit of glass on Sunday the 23rd afternoon and again on Monday the 31st afternoon, but with such small waves, it's more of a float than a surf.
The only standout, and I mean the only one worth keeping an eye on, is on Tuesday the 1st of September. We get a pulse of longer-period groundswell, with a 19-second period from the SSW. The swell height is still only 2ft, but the combined energy jumps to 443 – that's moderate energy and a sign of some real quality lurking in that deep water. The morning looks clear with a light offshore wind from the west. This is a long-period swell for a reef, so it could actually shape up nicely. It's the best on offer, but it's a long way out, so keep those expectations in check for now.
Beyond that, the surf stays small and messy through to the end of the 16-day window. The 6th of September sees some serious wind, which is a no-go for paddle surfing, but might be interesting for the kite crew.
So, in a nutshell: a whole lot of waiting for one promising morning on the 1st of September. Temper those expectations.
Rusty.

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.
