The Lowdown
G’day, I’m Rusty. Let’s look at Honokohau Harbour. First things first – the first ten days or so are a write-off. From Thursday the 27th of August through to about the 5th of September, there’s just nothing worth your time. It’s tiny, weak windswell, with onshores and cross-onshores making a mess of things. There’s a gap of over a week with no good options.
Things finally get interesting in the second week. Around Sunday the 6th of September, a long-period SSW groundswell shows up – periods of 15 to 18 seconds – and the combined energy starts climbing into the hundreds, like 394 on Sunday morning, then over 500 on Monday and Tuesday. Swell heights are around 2ft to 4ft, not huge, but that long period gives it some grunt.
The real standout is Tuesday the 8th of September afternoon. Honokohau Harbour (Big Island) gets a 4ft SSW swell with a 14-second period, and the wind goes glassy – dead calm. That’s gold. The combined energy is 557, so there’s plenty of push. This is a reef break that’s consistent and fairly exposed to the WNW optimum direction, and that SSW swell will wrap in clean. It’s an intermediate spot, and with glassy conditions, the surface will be perfect. Water temp is about 82°, a touch warmer than normal – feels like a warm bath. Crowds are possible, so expect company.
The Wednesday morning still has some swell but the wind turns cross-onshore from the NW, and by the afternoon it’s a moderate cross-shore with chop. So, don’t mess around – aim for that Tuesday afternoon session.
Overall, it’s a long wait, but that Tuesday the 8th of September is your one true standout. Otherwise, keep the board in the car.
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.
