The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for the next couple of weeks. Honestly, it's a bit of a flat spell to start with, so don't rush to grab your board just yet.
The first real hint of anything is not until Friday the 7th. The whole first week of August is a write-off for any decent waves. We're looking at a long gap with nothing but small, weak junk. Friday morning finally sees a tiny pulse of energy, but it's barely a ripple.
So, let's talk about the one spot we've got to work with: Honokohau Harbour. It's a reef setup, consistent, and takes a WNW swell best. The water is sitting at 81°F, which is about 2°F warmer than usual for this time of year – nothing crazy, just a touch on the balmy side.
That first glimpse of hope comes early Friday morning the 7th. We're talking a tiny 1.0ft swell from the SW, but with a period of 21 seconds. That is a very long period groundswell, which packs a punch for its height. The combined energy is moderate at best (139), but the real story is the glassy conditions. Clean as a whistle. It'll be small, and that long period might make it a bit tricky at a beach break, but on a reef like Honokohau, it could offer up a few nice, lined-up waves. This is a real window for the patient surfer.
The following Saturday and Sunday see similar tiny glassy moments, but the swell stays stubbornly small. We get a few afternoons with glassy conditions on the 8th (1ft, 18-second period, 204 energy) and the 9th (2ft, 12-second period, 137 energy), but these are very much "grab the log and go for a paddle" sessions, not a proper surf.
As we move into the second week, the swell picks up a little, but the wind turns cross-onshore and ruins it. From Monday the 10th through to Saturday the 15th, we see swell heights between 2ft and 3ft with moderate combined energy (up to 454), but it's nearly always choppy or blown out. There's a glimmer on the afternoon of Sunday the 16th, when a 2ft W swell with 14-second period meets glassy conditions. The combined energy is a solid 287 and the report says "expect good surf conditions." That's the standout, right there. It's a long way out, so don't bank on it, but if that holds, Honokohau Harbour with clean conditions and a bit of west in the swell will be the one to watch. After that, it drops right back off into the small stuff again.
The highlight is definitely the glassy, long-period windows on the 7th, and the promising forecast for the afternoon of the 16th. The rest is a waiting game.
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.
