The Lowdown
Alright folks, Rusty here with a look at the next couple of weeks at Honokohau Harbour. To be straight up with ya, it’s a pretty flat and frustrating start. We’ve got a solid gap of several days with basically nothing worth paddling out for.
The first chance of a surf comes on Wednesday the 12th, but it’s a real marginal one. We’re looking at a small 3ft swell from the SSW, with a period of 13 seconds. The real issue is it’s blowing cross-on at 3 mph, which is putting light ripples on the surface. The combined wave energy is pretty weak at 316, and the water is sitting at a touch warmer than normal, 82°, about 2° above average for this time of year. Honestly, it’s just about surfable but nothing to get excited about.
Thursday afternoon the 13th, the wind goes glassy, which is a major positive. The swell from the NNE is tiny at 3ft and a short period of 6 seconds, meaning weak, crumbly waves. The combined energy drops to just 99. It’s surfable but very ordinary.
Friday the 14th and Saturday the 15th are pretty much the same story. Small, weak swells in the 4ft to 4ft range, mostly from the NNE with a short period. The winds are mostly cross or cross-onshore, killing any real quality. Saturday afternoon the 15th turns glassy again, but we’re still dealing with a weak 4ft (232) swell. Still, it’s clean enough for a longboard if you’re desperate.
Sunday morning the 16th has glassy conditions on a tiny 3ft NNE swell (82). Then a big gap of poor, tiny conditions hits from Monday the 17th right through the second week. There’s a bit of a long-period SSW groundswell trying to fill in around the 23rd of August, with the combined energy climbing to 375 on Sunday morning. But the winds are light cross-on, and it’s still only 3ft. The energy builds nicely into the Monday the 24th and Tuesday the 25th, reaching a moderate 937. We’re seeing 4ft SSW swells with a 14-second period, which is a good long-period groundswell. But for a reef break like this, that long period can make the waves pitchy. The problem is, the winds are mostly onshore or cross-on, which will chop it up. It’s still a marginal call at best.
There’s no real standout session in this whole window. It’s a tough run for Honokohau. The consistency is there on the calendar, but the quality just isn't. Keep an eye on it, because forecasts can change, but for now, it’s a waiting game.
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.
Honokohau Harbour is 99 km (61 miles) from Hilo. If you plan a vacation in Big Island, look for hotels and other accommodation in Hilo. Hilo has rooms for a wide range of budgets as well as car hire and transport links.
