The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on offer for the next couple of weeks.
We’re looking at a bit of a slow start here at Honokohau Harbour. The first few days have some small swell rolling in, but it’s pretty marginal for a proper paddle session. The water is sitting at 82°, which is a touch warmer than average for this time of year, nothing too wild.
Sunday morning the 6th has a 4ft SW swell with a 12-second period. The wind is light and offshore, but there’s a risk of thunderstorms, and the energy is moderate (597). It’s surfable, but it’s hardly going to get the heart racing. The afternoon sees the swell bump up to 5ft, though the wind swings cross-onshore, so it’ll get a bit lumpy.
Monday the 7th is a bit more promising. The swell drops back to 4ft, but the period stretches out to 17 seconds, which is a proper long-period groundswell. The wind stays offshore and light, so the face should be clean. The energy is strong (1282), so there’s some push behind it. This is the best of the early window, but it’s still not huge. Tuesday the 8th sees a bigger 6ft swell, but the period drops to 10 seconds and the wind is moderate cross-shore, making it choppy and messy. Not great for a good time.
After that, we hit a long dry spell. From Wednesday the 9th right through to early in the second week, the swell drops off significantly, with heights under 3ft and poor wind conditions. There’s a whole lot of nothing happening for days. The energy is weak, mostly under 300, and the winds are cross-onshore or choppy. It’s a real flat patch.
There’s a tiny glimmer on Sunday the 13th afternoon. It’s a tiny 3ft swell from the NNE with a short 8-second period, but the wind goes glassy, making it dead clean. The energy is still low (150), so it’s more of a longboard or SUP session if you’re desperate.
The second week stays pretty quiet. Monday the 14th has a tiny 1ft swell with a 22-second period, which is a very long-period groundswell, but it’s just not enough size to do anything with. The wind is cross-onshore, so it’s a no-go. A few days later, around the 19th and 20th, we see the swell trying to push up to 3ft with a 15-second period, but the wind is bad, either cross-onshore or onshore, keeping conditions poor.
Honestly, the only standout here is Monday morning, the 7th of September. That 4ft, 17-second groundswell from the SSW with light offshore wind is the cleanest window of the whole forecast. The energy is strong (1282), and that long period will give you some nice, lined-up waves at this reef break. The rest of the time is a real struggle. The crowds are listed as “sometimes” here, so when it’s good, you might see a few others out, but with this forecast, I doubt it’ll be packed.
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.
