The Lowdown
Alright folks, Rusty here. Let’s take a look at what we’ve got cooking for Honokohau Harbour over the next couple of weeks. The truth is, we’re in for a long, slow stretch. The first solid, recommendable surf doesn’t show up until mid-week, so don’t be in a rush.
Right now, starting Sunday the 13th, it’s flat and pretty hopeless. We’ve got tiny 1ft swell with poor conditions and barely any energy (161). That carries right through Monday and into Tuesday morning. The swell does start to bump up a little on Tuesday the 15th, with 2ft from the SW and moderate wave energy building (385 to 402), but it’s still marginal and the wind is on it. Nothing to get excited about yet.
Wednesday the 16th afternoon is the first real glimmer of hope. The swell picks up to 3ft from the SSW, and here’s the kicker – the wind goes glassy. That’s a beautiful thing. The energy is solid (459), and the forecast says expect good surf conditions. This is your first real chance to get a clean wave at Honokohau Harbour. The swell direction from the SSW is right in that sweet spot for this reef break, which is fairly exposed to the WNW. Water temps are about average for this time of year, so no surprises there.
We get another tease on Saturday the 19th afternoon. Again, 3ft from the SSW, glassy wind, and strong energy (573). If you missed Wednesday, this is your second shot. But honestly, for the size, the best bet is the Wednesday afternoon window.
After that, things get a little messy. There’s another glassy window on Monday the 21st afternoon with 3ft from the SSW and moderate energy (338), but it’s not as punchy. The following week is a real mixed bag of onshore wind and tiny surf, with only a few flickers of cleaner conditions. The 24th of September afternoon shows a clean, cross-off wind with 2ft from the SW and decent energy (286), but that’s a week and a half out – promising but less certain.
Overall, the standout session is Wednesday the 16th afternoon. Clean glass, small but rideable SSW swell, and enough energy to make it fun for an intermediate. If you can’t make that, the Saturday the 19th afternoon is your backup. The rest of the 16-day window is mostly a waiting game with marginal to poor conditions. It’s a quiet run, but that’s how it goes sometimes.
Rusty.

A general guide to surfing at Honokohau Harbour can be found by selecting the local surf guide option on the grey menu.

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.
