The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for Honokohau Harbour.
Honestly, we've got a bit of a sleepy start. For the first few days, from Friday the 28th right through to the start of September, the surf is just not happening. Small, weak, and messy. You're looking at a lot of "poor surf conditions" with tiny ripples and cross-onshore breezes. It's a waiting game. The only thing worth noting right now is the water, which is sitting at a balmy 82°, about a degree and a half warmer than usual for this time of year.
But then, things get interesting. The standout session, the one to circle on your calendar, is Tuesday morning, September 1st. We’ve got a nice pulse of long-period groundswell rolling in from the SSW at about 3 ft, with a period of 18 seconds. The winds go glassy, dead calm. The combined energy reading is a solid 671 – that’s moderate to strong energy – and the report says "expect very good surf conditions." That’s the pick of the first week, right there. That long period will shape up nicely at this reef break, with plenty of time between sets.
After that, it gets quiet again for a good long stretch. There’s another glimmer of hope on Monday, September 7th. The morning looks good with glassy 2 ft SSW swell, but the standout that day is definitely the afternoon. You’ve got the same clean, glassy conditions, but the swell bumps up to about 3 ft from the SSW with an 18-second period, and the energy is pumping at 807. The report is calling for "very good surf conditions" that afternoon.
Into the second week, there are some other pulses to keep an eye on. Tuesday, September 8th afternoon looks clean again – glassy winds, 3 ft SSW swell, and that same strong energy reading of 671. And then Thursday morning, September 11th brings a slightly bigger push of 4 ft from the SSW, but the wind is cross-onshore and the period is shorter at 10 seconds, so it’s going to be a bit messier. The energy is still there at 597, but it won't be as clean as the other windows. For the rest of the run into mid-September, it’s mostly small and marginal.
So, to sum it up: the true standouts are Tuesday morning, September 1st, and Monday afternoon, September 7th. Both have that magic combo of clean, glassy conditions and solid, long-period groundswell. The 1st is the more reliable near-term call, while the 7th is a promising long-range target.
Keep your eyes on the horizon, and stay stoked.
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.
