The Lowdown
Alright folks, Rusty here. Let’s see what’s happening in our corner of the Pacific.
Honokohau Harbour is a reef set-up, and honestly, it’s a bit of a slow starter. We’ve got a long gap of poor conditions right through the opening weekend and into the start of next week. The water is sitting at 81.3°, which is about average for this time of year, so nothing weird there.
The first real glimmer of hope shows up on Thursday afternoon, the 13th. The swell is only 3.6ft from the NNE, but the wind goes glassy. That’s a major positive. The wave energy is low though, at (133), so it’s not going to be pumping. It’s just a small, clean window.
But the standout, without a doubt, is Friday afternoon, the 14th of August. The swell jumps to 9.8ft from the NNE, and the wind is glassy. That’s a big one. The combined energy hits (993) – that’s strong stuff. This is a proper groundswell with a short period of 7 seconds, so it’s going to be a bit dumpy and fast. For a reef break, that can be a handful, but for experts, this is where it’s at. The water is still glassy, so expect clean, powerful, and challenging waves. Crowds are possible here, so get in early if you’ve got the skill.
After that, the swell drops off a cliff. The rest of the run looks poor again, with small, weak swells and onshore winds ruining the shape. There’s a tiny, glassy window on Monday morning, the 17th, with a 1.3ft WNW swell, but you’d be scratching for a ride.
So, call it. Friday afternoon, the 14th, is the one. Big, powerful, glassy. The rest of the window is a write-off.

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.
