The Lowdown
Alright, let's talk it through in feet.
Honokohau Harbour. It's a slow start overall, and we're in for a long, drawn-out period of small surf. The water's sitting at about 81°, which is a bit warmer than normal, maybe a degree above average.
The clear winner in the whole 16 days is Sunday afternoon, August 9th. You’ve got glassy conditions, a light WSW wind at 3 mph, and a tiny but clean 2ft SSW swell with a 12-second period. The energy is weak, but that glassy surface is perfect. It'll be a fun, mellow session with no crowds.
After that, things get messy. Monday the 10th and Tuesday the 11th bring a little more size, around 3ft, and a solid 15-second period, but the wind turns onshore or cross-onshore, making it marginal at best. Not worth pushing for.
The rest of the first week is just small, messy, or both. A few glassy windows on Thursday the 13th and Friday the 14th, but those are with tiny 2-3ft swells at a short 6-second period – just not enough push.
Saturday the 15th afternoon sees a jump to nearly 6ft, but at a terrible 6 seconds. That’s just short-period bump, and with a light cross-shore wind, it’ll be choppy and sectiony. Better suited for a kite than a surfboard.
From the 16th through the 23rd, it’s mostly poor conditions with onshore winds and very low energy. There's a small glimmer on Thursday the 20th morning – a 2ft SW groundswell at a very long 18 seconds, but with a cross-onshore wind. It could wrap in nicely but it's small and far off.
The last call is Monday the 24th afternoon, with 3ft SSW swell at 14 seconds and fair energy, but with that onshore wind, it’s just another marginal day.
Bottom line: Sunday afternoon, August 9th, is your session. Small and clean, that’s the one. Otherwise, it’s a waiting game.

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.
