The Lowdown
Alright mate, Rusty here. Let’s have a look at what’s on the cards for our little patch of reef.
Right off the bat, I gotta be straight with you – the next few weeks are looking pretty grim. We’ve got a long stretch of nothing special, with mostly small, messy swell and dodgy wind. The water temp is sitting about average for the time of year, nothing wild there.
The only real standout in the whole 16-day window arrives towards the end. We’re looking at Saturday the 5th of September into the following few days. The afternoon of the 5th is the pick of the bunch. We’ve got a 2ft swell from the SSW, with a long period of 19 seconds. That’s proper groundswell energy, and the combined energy is a solid 432 (moderate), so there’s some grunt behind it. The wind goes glassy for that afternoon, which is a major bonus – it’ll be clean as a whistle. This is a proper reef break, so that long-period swell will wrap in nicely.
Now, the 6th of September Sunday morning will still have some size and long period, but the wind is going onshore, so it’s a bit of a gamble. Then the 8th of September Tuesday sees the biggest swell of the run, with 8ft from the SSW. That’s a serious size, only for the experienced crew. The wind is a cross-shore at 16 mph, which will chop it up, and the combined energy is a whopping 1619 (strong). It’s a lot of water moving, but not pretty.
The rest of the time is a write-off. Small, short-period windswell, cross-onshore breezes, and scores that don’t give you much to get excited about. There’s a big gap of nothing useful from the start all the way through to the end of August. If you’re a kiter, the bigger, choppier days on the 8th might be more your scene than a surfer’s.
So, save your energy for that Saturday the 5th. It’s a long way off, so keep an eye on the charts, but it’s the only real window we’ve got.
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.

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.
