The Lowdown
Alright, Rusty here again. Let’s break it down.
First few days are a total dud. Wednesday 2nd through Friday 4th September – tiny, weak swell, poor conditions. Don’t bother.
Saturday 5th September morning brings a change. A new SSW groundswell shows up at 6ft with a 12-second period, moderate energy (880). Still a bit cross-onshore, but it’s a start. The afternoon cleans up a little.
Sunday 6th September holds 6ft from the SW, same period, and the energy jumps to strong (907 in the morning, 1262 in the afternoon). Wind is still a little cross-onshore.
Now, Monday 7th September afternoon is the real deal. Swell is 6ft from the SW, period 13 seconds, and the wind goes glassy – dead calm. That’s gold. The energy is very strong (1684), and the wave report says excellent for experienced surfers. Honokohau Harbour (Big Island) is a reef break, so that long-period swell will wrap in clean. Crowds are sometimes a factor, so be ready. This is the best of the first week.
Tuesday 8th September is a monster, but only for experts. We’re talking 12ft from the WSW with a 15-second period, and energy is massive (5224). But the wind is a strong cross-shore at 15 mph, making it choppy and rough. Kite surfers might love it, but paddle surfers will struggle. The afternoon is still 12ft with a 13-second period and cross-wind.
Wednesday 9th September drops to 5ft from the SW, but the afternoon has a clean cross-offshore wind. Decent, but not the highlight.
After that, from Thursday 10th September onward, the swell fades to 1ft to 2ft, with long periods (15-24 seconds) but very weak energy (mostly under 500). Conditions are poor with light onshore winds. The second week is a snooze.
So the standout is Monday 7th September afternoon at Honokohau Harbour – glassy, 6ft SW groundswell, long period. That’s your session. Tuesday 8th is for the big-wave crew only.
Water temp is 82°F, about 1°F warmer than average – just a little on the warm side.
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.
