The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Honokohau Harbour over the next couple of weeks.
Right off the bat, we’ve got a long slow start. The first few days are pretty much a write-off for a proper paddle session. Wednesday the 26th and Thursday the 27th have some small swell, but the conditions are poor, with cross or cross-onshore winds making it messy. The best we see early on is Thursday morning the 27th – that’s a glassy window with a 3ft SSW swell and a period of 16 seconds, which is a nice long groundswell. The combined energy is moderate (428), and with that glassy wind, it’ll be clean. But this is a reef break, so that long period will make it suck a bit straighter, but it should still offer some fun lines for an intermediate. Water temp is sitting at 82°, which is a touch warmer than normal for this time of year.
After that brief moment, it’s back to the doldrums. From Friday the 28th right through to the end of August, it’s mostly tiny, weak, or onshore junk. The swell drops to 1ft to 2ft, the energy is low (under 100), and the wind is rarely in our favour. There’s a glassy session on Monday morning the 31st with a 2ft SW swell and 15-second period, but it’s just ordinary, surfable but nothing to get excited about.
The first week of September looks more promising but still inconsistent. Tuesday the 1st has a 3ft SSW swell with a long 18-second period, and the combined energy jumps to 664, which is solid moderate. But the wind is cross-onshore, so it’s marginal. Then we go through a stretch of nothing much until the 7th and 8th of September. Monday the 7th has a 3ft to 4ft SSW swell, 15-second period, and energy over 500, but the wind is onshore or cross-onshore, making it only marginal. The real standout comes on Tuesday afternoon the 8th of September – glassy conditions, 3ft SSW swell, 14-second period, and energy of 411. That’s a clean, fun-sized wave for the reef. That’s your best bet in the whole 16-day window, but it’s over a week away, so keep an eye on it.
Overall, this is a quiet run for Honokohau. There’s a couple of half-decent mornings, but nothing that’ll have you calling in sick. The reef will offer some shape when the swell direction is right, but the wind is the real spoiler most days. It’s not a complete blank, but it’s close.
Rusty.

Information about the Honokohau Harbour Surf forecast
The above surf forecast table for Honokohau Harbour provides essential information for determining whether the surfing conditions will be good over the next 16 days. 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.
