The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for the next couple of weeks at Honokohau Harbour.
First up, the water is sitting at a warm 81°F right now, which is about 2°F above the norm for this time of year – a touch toastier than usual, but nothing wild.
The overall pattern is pretty flat and disappointing for the first week. There’s a lot of small, weak, short-period windswell, and the wind is mostly cross-on or onshore, chopping things up. The combined energy is all over the place, but even when it bumps up to moderate levels on Monday the 10th, the wave quality is still marginal at best. Honestly, the first few days are a write-off.
We finally get a glimmer of hope on Wednesday morning, August 12th. The wind goes glassy, light, from the WNW, which is perfectly offshore for this reef. The swell is a tiny 3ft from the SSW, but with a period of 13 seconds it’s got a bit of groundswell in it. The energy is moderate. It’s a small, clean day for the patient surfer on an intermediate board. The crowds are *sometimes* an issue here, so you might have a few others in the water, but on a Wednesday morning it could be just you and a couple of mates.
After that, the window slams shut again. The rest of the 12th and the 13th are back to tiny, weak, or poor conditions. There’s a pulse of bigger swell around the 15th and 16th, with heights hitting 5ft to 6ft from the NNE, but the period is a rubbish 7 seconds – that’s pure windswell, fat and bumpy. The wind is mostly cross-on, so it’s not going to be pretty. It’s a pass.
The next real standout is a long way off. Saturday, August 22nd looks promising, but it’s over a week away so keep your expectations in check. The morning shows a 2ft swell from the SSW with a very long 19-second period. That’s proper groundswell energy, and the combined energy is solid. The wind is light and onshore from the west, which is okay for this spot. This sort of long-period groundswell is usually better for a point or a reef, and Honokohau is a reef, so that’s a good match. The afternoon gets a bit choppier with the cross-on wind, but the morning session could be the best of the whole 16 days.
The bottom line: The first week is a gutter. The only real, clean-inside chance is Wednesday morning, August 12th for a glassy, small wave. The bigger, longer-period groundswell that shows up on Saturday, August 22nd is the one to circle on the calendar, but it’s a long way out and the wind could change.
Stay patient, keep your eyes on the horizon.
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.
