The Lowdown
Alright, Rusty here again. Let’s break down what’s coming in feet and miles per hour.
The first few days are a total washout. From Monday the 20th to Wednesday morning the 22nd, we’re looking at tiny, weak swell and cross-onshore wind. The energy is super low, so don’t bother getting wet.
Things start to perk up from Wednesday afternoon the 22nd into the next week. A long-period SSW groundswell moves in, with swell periods of 20 to 24 seconds. That’s the kind of energy that pushes proper waves, but it also means longer waits between sets. The wind stays light but mostly cross-onshore, so the surface won’t be perfect.
The best window – and I mean the *only* real standout – is Sunday the 26th. By the afternoon, the wind goes glassy, dead flat. That 1.0m (3ft) SSW swell with a 16-second period will be clean and organized. For a reef like Honokohau Harbour, that’s a dreamy setup. The water is a warm 27°, right where it should be for this time of year, and the crowd is only “sometimes” an issue.
After that, the swell fades quickly. Tuesday the 28th has another glassy afternoon, but the waves are small and the period is dropping. The 29th sees a switch to a weak northerly swell with a pathetic 7-second period – energy is near zero, so don’t even think about it.
The first week of August is mostly flat or weak, with tiny SW pulses and often bumpy wind. There’s nothing that screams “go.”
So, circle Sunday the 26th. That’s your day. The rest is for the patient or the sunbathers.
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.
