The Lowdown
Alright folks, Rusty here. Let's have a look at what's cooking for this stretch of coast.
Honestly, it's a tale of two halves. We're looking at a pretty quiet start with a lot of small, messy days. The first week is gonna be a struggle, but if you can wait, the second week, especially around the 7th of September, shapes up as the real deal. The water temp is about average for this time of year, so nothing unusual there.
Let's start with Honokohau Harbour, which is a reef break. The first few days, from the 30th of August right through the start of September, are looking pretty grim. We're talking tiny waves, cross-onshore winds, and the combined energy is just weak, often under 100 (90). It's not worth paddling out for.
Things stay small through Thursday the 3rd and Friday the 4th. The swell is tiny, but we do get a few moments of glassy conditions. Friday afternoon, the swell is a weak 3ft from the NNE with a short period of 6 seconds, and the combined energy is moderate at 132. It's surfable, but it's not going to get your heart racing.
The weekend of the 5th and 6th gets blown out with strong cross-onshore winds and choppy conditions. The energy picks up a bit, but it's all messy. Not good for a paddle.
Now, here's the standout. Mark your calendar for Monday the 7th of September. This is the best on offer. We’ve got a 3ft groundswell from the SSW, with a long period of 17 seconds, and it's glassy. The combined energy is strong, hitting 697. The reef at Honokohau Harbour should handle that long-period energy well, offering clean, lined-up waves. Tuesday the 8th morning is still good, with glassy conditions and a 3ft SSW swell, though the period drops to 15 seconds (energy at 488).
After that, the swell drops off again. The second week fades into mushier, cross-onshore conditions and smaller swells, with the odd glassy moment but nothing to write home about. The 14th of September has a tiny 1ft swell with a very long 21-second period, but it's straight onshore and the energy is moderate (393), so it's a long wait for a weak wave.
So, to sum it up: the first week is a write-off for most. The real window is Monday the 7th of September. That's your best bet for a proper session.
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.
