The Lowdown
Alright folks, Rusty here. Let’s get into it for Honokohau Harbour.
First up, we’re looking at a pretty quiet stretch overall. The water temp is sitting around 80°, which is pretty normal for the time of year, nothing wild there.
The first few days aren't really worth paddling out for. Monday the 20th and Tuesday the 21st are a write-off – tiny 1ft swell from the SW with a cross-on breeze, just poor surf. It’s basically flat and bumpy. The combined energy is weak (127). Wednesday the 22nd through Friday the 24th shows a bit more push in the water, with swell climbing to 2ft-3ft, but the quality is still shot because of that constant cross-on wind. The energy picks up into the moderate range (512 to 753), but the conditions are just marginal at best, with a "questionable tide" note.
The first real glimmer of hope comes on Saturday the 25th. The swell bumps up to 4ft from the SSW, and the wind swings to a clean cross-shore. Combined energy is a solid 913, which is strong. Still, it’s only rated as marginal. That’s the best of the first week, but it’s not a standout.
Now, Sunday the 26th morning is where it’s at. The wind goes glassy, light offshore from the WNW, and you’ve got a 3ft SSW groundswell with a decent period (16 seconds). That’s the best window in the whole 16-day run. The reef setup at Honokohau Harbour should handle that long-period swell well, giving you clean, lined-up waves. It’s a bit of a window, though – the afternoon goes back to marginal.
After that, it’s a slow downhill slide. The swell drops and the winds stay messy, with lots of cross-on conditions. You’ll see a few 2ft-3ft days, but nothing with the same quality. The energy drops off a cliff, back below 100 after the 1st of August. The last few days, from the 1st to the 4th of August, are almost flat with weak energy (41-85), so you can put the board away.
The only standout worth mentioning is the Sunday 26th July morning session. 3ft of clean, glassy SSW groundswell. That’s your best bet. After that, the forecast is a long gap of poor conditions, with a couple of very marginal mornings on the 2nd of August that are barely surfable. It’s a classic case of a short, sharp window of goodness, then a long wait.
Rusty out.

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.
