The Lowdown
Alright, let’s get into it.
The next couple of weeks are looking pretty flat and pretty uninspiring for Honokohau Harbour. We’ve got a long stretch of small, weak surf ahead, and honestly, for the first week or so, you’re not going to want to paddle out. It’s a real waiting game. We’re looking at a good week plus of nothing worth getting wet for, so don’t rush to charge your batteries just yet.
Starting Tuesday afternoon, there is a little bump of 5ft from the west, but it’s coming with a cross-on wind that’s making it messy. This one’s got some energy behind it, but it's going to be a junky sort of surf, not worth your time.
Then we go into a real quiet spell. Through Wednesday, Thursday, Friday and right through the weekend, it’s tiny, with waves down around 1ft to 3ft. The winds are mostly light but often onshore or cross, so the little waves we do have are going to be chopped up. There’s a bit of a long period swell showing on Monday with 23 seconds, but the size is just not there.
After that first week of flatness, we finally start to see a little pulse of energy. Monday afternoon brings some glassy conditions with a small 1ft swell, and Tuesday the swell bumps up to a tiny 2ft with the same glassy wind. It’s not going to be epic, but it will be rideable on a longboard. That Tuesday afternoon is probably your first real chance to get a few clean little waves.
From the 16th onwards, we see a slight uptick in size, with waves in the 2ft to 3ft range, and these come with a better period and a bit more energy. It’s still small, but it’s more promising. The winds are mostly light, and there are a few windows of glassy conditions to be had.
The standout in this run, if you can call it that, is probably the 14th of September Monday afternoon. It’s glassy, with a clean 1ft wave and a long period. Another one to keep an eye on is the 15th Tuesday afternoon, also with glassy conditions and a bit more size at 2ft. These are your best bets, but don't expect much. It’s going to be a longboard kind of week.
Later on, around the 18th and 19th, there are signs of a bit more energy with the swell getting up to 3ft. But we need the winds to play nice, and they’re a bit iffy.
Overall, it’s a lean period. We have almost a week of flatness at the start. It’s the kind of stretch where you might be better off fixing a ding or just enjoying the beach, because the surf isn’t cooperating. The water temp is sitting right around the average for this time of year. For this spot, it’s pretty consistent, and there’s always some energy to be found when it builds, so I wouldn’t write it off completely, but for now, I’d be patient.
Alright, that's the word for now.

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.
