The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the menu for Honokohau Harbour over the next couple of weeks.

It’s going to be a slow start for the first few days, with nothing really worth paddling out for. The water temp is sitting at 82°F, which is about 1°F warmer than usual for this time of year – nothing too wild, just a touch of tropical warmth. The first real chance of anything decent comes on Monday the 7th of September, and that’s the standout window. Glassy conditions in the morning with a solid 8 ft swell from the SW at a long 14-second period – that’s a proper groundswell. The energy is pumping in at 3349 (moderate to strong). This is excellent for experienced surfers, but at that size, beginners should sit this one out. The swell direction (SW) is a good match for the optimum WNW direction, and with the reef bottom, those long-period lines should hold up nicely. It’s a consistent spot, but crowds are possible, so get in early.

The run-up to that Monday is pretty ordinary. Thursday the 3rd is glassy with a tiny 3 ft swell from the NNE, but only 7-second period – weak energy (96) and very average. Friday morning and Saturday see some small onshore junk, not worth your time. Saturday afternoon and Sunday get a bit more size (5 ft to 6 ft) from the SSW/SW with a better 12-second period, but the wind is cross-on or onshore, and the energy is moderate (up to 1289), so it’s a marginal call at best.

After the Monday morning highlight, the Monday afternoon turns into a mess – cross-shore wind at 16 mph and 10 ft swell from the WSW. That’s too big for most, and the wind will tear it up. For the rest of the week, the size drops back to 3 ft to 3 ft. Tuesday morning the 8th is cross-onshore and choppy, but Tuesday afternoon goes glassy with a 3 ft SW swell (14 seconds) and energy of 976 – a small but clean option for a quick session. Wednesday the 9th is just small and a bit bumpy again.

The second week, from the 10th of September onward, is a real letdown. Swell stays tiny, between 1.0 ft and 3 ft, with periods mostly between 15 and 24 seconds – long period, but no height to work with. The best of a bad bunch is Wednesday the 16th afternoon, when it goes glassy again with a 3 ft SSW swell at 18 seconds (energy 596). That’s surfable, but it’s a long stretch of small, weak waves. From the 11th to the 14th is a real dry spell with mostly poor conditions. The 15th and 16th show a slight flicker of life, but it’s still marginal.

So, to sum it up: the one standout is Monday morning the 7th of September at Honokohau Harbour. If you’re experienced and can handle 8 ft, that’s your window. The rest of the 16 days is mostly small, weak, or wind-affected. A few glassy moments in the second week, but don’t get your hopes up.

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.
