The Lowdown
Alright, Rusty here. Let’s talk about what’s happening at Honokohau Harbour.
First off, the water’s running a touch warmer than normal for this time of year, sitting at 81°, so that’s a nice bonus if you’re paddling out.
Honestly, the next week and a half is pretty flat and frustrating. From Monday 3rd August right through to the weekend, we’re looking at tiny, weak swell. The waves are small, under 2ft, and the energy is minimal (24–100). The winds are mostly cross-onshore or onshore, which doesn’t help. There’s a brief moment on Tuesday afternoon (4th August) where it goes glassy with a tiny 2ft SSW swell, but it’s still very ordinary. Don’t get your hopes up.
There’s a gap of several days with no real recommendations. The surf is just too small and weak to bother.
The first real glimmer comes on Saturday 8th August afternoon. The wind drops to glassy, calm conditions, and the swell bumps up a touch with a long period SSW groundswell at 18 seconds. The energy jumps to 204 (moderate). It’s still only 1ft, so it’s small, but that long period means the shape could be there for a reef setup like Honokohau. It’s a reef break, consistent, and exposed to the WNW – the swell is from the SSW, so it’s not the optimum direction, but with glass, it might offer a few fun ones. Crowds are possible here sometimes.
The standout window is the second week. From around Monday 10th August, the swell starts to build. By Friday 14th August morning, we’ve got a solid 3ft WNW groundswell with a period of 16 seconds, and the energy is strong at 518. That’s decent energy. The catch? The wind is cross-onshore, so it’s not clean. But the swell direction is lining up much better with the break’s optimum WNW direction.
The best single session looks to be Sunday 16th August afternoon. The swell holds at 3ft from the WNW with a period of 14 seconds, the energy is 351 (moderate to strong), and more importantly, the wind goes glassy. That’s the one to circle. Clean, lined-up waves on a reef that holds consistent swell. For a reef break, that long period (14 seconds) will give you some nice, pushy sets. It’s not huge, but it’ll be clean and fun for intermediates.
If you want a bit more size, the Thursday 13th and Friday 14th have bigger swell (2–3ft) and stronger energy (408–542), but the wind is onshore or cross-onshore, so expect some chop. Still, the energy is there.
Overall, don’t expect much in the first week. The second week has promise, but it’s a patience game. The standout is definitely Sunday 16th August afternoon for the glassy, clean conditions.

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.
