The Lowdown
Alright folks, Rusty here. Let’s get straight into it. We’ve got a real mixed bag of a forecast for the next couple of weeks at Honokohau Harbour. The honest truth is, for the next ten days, it’s looking pretty grim – mostly small, messy, and not worth paddling out for. The first real chance for a decent wave doesn’t show up until the end of the month, so we’re looking at a long stretch of flat-to-poor conditions. The water’s sitting at 80°, which is about average for this time of year, nothing wild there.
The only bright spot in this whole outlook is on Sunday, July 26th. That afternoon, we get a nice little pulse of swell from the SSW pushing 4ft, and the wind swings around to a light NNE cross-off at just 3 mph. That’s clean, groomed surf. The combined energy is strong at 1035, so there’s some proper oomph behind it. The period is 17 seconds, a real groundswell, which will make for some well-shaped, powerful lines. Given it’s a reef break, this long period will be a blessing, not a curse. This is the standout window. The morning of the 26th is also a looker with a 4ft SSW swell and light cross-on winds, but the afternoon is the true winner.
The rest of the run is a write-off. There’s a tiny window on the morning of Saturday, July 25th, with a 4ft SSW swell, but the wind is a cross-on, and the forecast is only marginal. It’s not enough to get excited about. The long period swells we see around the 22nd and 23rd of July (up to 24 seconds) are huge, but the wave heights are under 3ft, and the wind is messy. That’s a lot of deep-water energy that just won’t stand up properly on the reef.
So, to sum it up: you’re waiting for that Sunday afternoon, July 26th. That’s your session. Everything else is a skunk. The first week-plus is a dead zone, so don’t bother checking the cam until we get close to that date.

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.
