The Lowdown
Alright, Rusty here, checking in on Honokohau Harbour. Gonna be honest with you, the next couple of weeks are looking pretty slim.
The water’s sitting at about 82°, which is a touch warmer than average, nothing to write home about. This is a consistent reef break that handles a WNW swell best, but we’re mostly seeing short-period NNE stuff coming through, which just doesn’t work here.
We start off with a bit of a pulse on Saturday the 15th, with a 6ft swell from the NNE, a short 8-second period, and a combined energy of 396 (moderate). The morning has a cross-on wind, making it messy. The afternoon cleans up with a cross-off, but the wind is a fresh 22 mph breeze, and the swell pushes to 8ft. That’s a big, short-period wave, only for the experts. Not a friendly start.
Then it’s basically a desert. From Sunday the 16th right through the end of the month, we’re looking at tiny, weak surf. Swell heights are mostly in the 1ft to 3ft range, with combined energy often under 100 (weak) or just barely into the low hundreds. There are a few glassy afternoons, like on the 18th and 19th, but with waves only 1ft and a very long 18-second period, it’s dead flat. That long period at a reef break makes for slow, fat lines that barely break.
The only thing that even looks like a pulse comes on the 30th of August, a Sunday morning. We see a 4ft swell from the NNE, with a combined energy of 330 (moderate), but it’s still a short 6-second period, and the wind is blowing onshore. Still marginal.
So, there’s no real standout session here. The spot is consistent, so it can turn around, but for this 16-day run, you’re probably better off doing something else. The best bet is a tiny, glassy, flat wave if you’re desperate, but don’t expect any real punch.
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. 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.
