The Lowdown
Alright, this is Rusty, and I’m looking at the next couple of weeks here at Honokohau Harbour. We’ve got a classic little run of very clean, small, long-period groundswell coming in right off the bat, but the rest of the window is a grind. The water is sitting at 82°, which is a touch warmer than normal for this time of year.
The standout is this Sunday morning, August 23rd. We’ve got a glassy 2 ft swell from the SSW with a very long period of 16 seconds. The energy is moderate (327), and with the wind dead calm, it’s going to be ultra clean. This is a proper reef setup, so that long period will wrap in nicely. Afternoon sees the same conditions with the wind dropping to zero – glassy again. That’s the pick of the whole forecast.
Monday morning, the 24th, gets a little bump to 3 ft, but the wind swings around to a light cross-onshore, so it’s not as clean. The energy drops a bit (234). The rest of the week through the 25th to the 28th is mostly poor surf with cross-on or onshore winds and very small swell. Not worth paddling out for.
We get a brief reprieve on the afternoon of Saturday the 29th with glassy conditions again, but the swell is tiny at 1 ft and the energy is low (126). It’s surfable but very ordinary. That’s the story for the 30th as well.
Then we hit a real flat spell. From the 31st of August all the way through the 4th of September, the waves are virtually non-existent, with energy readings dropping below 100 and winds mostly cross-on or onshore. There’s nothing to recommend.
Way out at the end of the window, we see a promising but less certain sign. On the morning of September 5th, we get a 1 ft swell from the SSW with a very long period of 21 seconds. The energy is moderate (199) but the conditions are poor. The afternoon of the 5th and the 6th look a little better, but still marginal. The 7th of September has a 3 ft SSW swell with a 16-second period and moderate energy (427), but the wind is onshore. It’s a long way off, so keep an eye on it, but it’s not looking like a sure thing.
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.
