The Lowdown
Alright, this is Rusty with a look at the next two weeks of surf here at Honokohau Harbour.
Right off the bat, I gotta be straight with you: the next week and a half is looking pretty flat and uninspiring. We’ve got a long stretch of tiny, weak swell with poor conditions. The water is a touch warmer than usual for this time of year, sitting at 82°, but that’s about the only thing going for us.
The first real chance to wet a line comes on Saturday, the 22nd of August. In the afternoon, the wind is gonna go glassy, and we’ll see a tiny 2ft swell from the SW. It’s not much, but that glassy, clean surface will make it super fun on a longboard. The combined wave energy is moderate at 276. Then on Sunday, the 23rd, the morning’s a bit of a write-off, but the afternoon shows another window of glassy conditions with the same tiny 2ft SSW swell, though the conditions are just ordinary.
Honestly, the standout moment in this whole forecast is the afternoon of Saturday, the 22nd. That’s your best bet for a clean, glassy session, even if the waves are knee-high.
After that, we’ve got a real dry spell of poor surf from the 24th of August all the way through the end of the month. The swell is tiny and the wind is mostly onshore or cross-onshore, so it’s just not worth paddling out for.
The end of the forecast period, around the 1st and 2nd of September, shows a bit more energy in the water, with some long-period groundswell from the SSW. We’re talking about 3ft waves with a period of 18 seconds, which is nice and long, and combined energy climbing into the strong range (761). The wind looks clean on the morning of the 1st (Tuesday) and the 2nd (Wednesday), being cross-offshore. But don’t get too amped—the forecast is far out and the scores are still just marginal. It’s promising, but keep your expectations in check for that one.
So, to sum it up: grab the log for a glassy, tiny session on Saturday the 22nd. Otherwise, it’s a waiting game for a potential groundswell pulse in the first few days of September.
Stay safe, keep your eyes on the horizon, and I’ll catch you down the line.
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.
