The Lowdown
Right folks, Rusty here. Let’s have a look at what’s coming up for Honokohau Harbour.
Honestly, it’s a flat spell. The next week and a half is total non-starter. From Friday the 31st of July right through to Saturday the 8th of August, there’s nothing doing. The combined swell energy is weak, barely hitting three digits most days, and the swell height is tiny – we’re talking 1ft to 2ft rubbish. The wind is mostly cross-on, not helping, and every single session is flagged as "poor surf conditions." This harbour is a reef break that’s fairly exposed to the swell, but a WNW optimum doesn’t match the tiny, short-period junk we’re seeing. Even the periods that are long (16 seconds) are wasted on this tiny swell. It’s a brutal stretch of flatness, about nine days of nothing worth paddling for.
Now, things start to shift around Sunday the 9th of August. We get a bit of a pulse coming through – a long-period groundswell from the SSW at 18 seconds, pushing the height up to 2ft to 3ft. The combined energy jumps to 587 (moderate), and climbs to 737 by the afternoon. The wind stays light, which is a positive, but the swell direction is cross-on, so it’s still not clean. The forecast calls it "marginal," and honestly, it’s just a glimmer. The water temperature is about average for the time of year, nothing wild.
The standout window, if you can call it that, rolls into Monday the 10th of August. That morning, we get a 3ft SSW swell with a 16-second period, and the combined energy hits 863. The wind is offshore from the W, which is a major positive – clean faces. The score is a 2 out of 10, which is the best we’ll see across the whole 16 days. The swell is still small, but that offshore wind is going to make it glassy and rideable for an intermediate. The afternoon sees a risk of thunderstorms, but the swell nudges 4ft with 925 energy (moderate-strong). It’s still marginal, but it’s the pick of a very poor run. After that, it’s back to small, weak, onshore junk through to Saturday the 15th of August.
So, the only real standout is Monday the 10th of August, morning session at Honokohau Harbour. Clean offshore wind, a bit of long-period SSW groundswell. It won’t be big, but it’ll be the most fun you’ll have in this otherwise dead outlook. The rest is a write-off. Don’t get your hopes up for anything else.
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.
