The Lowdown

G'day, Rusty here. Alright, let's have a look at what's on the cards for the coming days. Honestly, it’s a pretty quiet run for the foreseeable future, so don't be in a rush to wax up.

We're looking at Honokohau Harbour, a reef setup that's fairly exposed to the WNW. The water's sitting at a touch warmer than normal for this time of year, about 82°F.

The pattern for the next couple of weeks is mostly small, weak swell with crummy wind angles. The combined swell energy kicks off around 234, which is moderate, but it's paired with poor conditions. For Friday the 21st and through the weekend, we're seeing small 2ft to 2ft SSW swell with a long 16-second period, but the wind is cross-onshore, so it's messy. Not worth paddling out.

We get a minor glimmer of hope on Sunday the 23rd morning. The wind goes light offshore from the WNW, and the combined energy lifts a bit to 329, but it’s still only 2ft of swell. It's marginal at best. That pattern hangs around for days – just tiny, weak swell and a cross-onshore breeze. Wednesday the 26th morning offers a rare glassy moment with 2ft SSW swell and a 14-second period, but the energy is weak at 206. It's surfable, but ordinary.

There's a long gap of nothing promising until we get to Tuesday the 1st of September. That afternoon looks like the standout of the whole forecast period. The wind goes glassy, and we get 3ft of long-period SSW groundswell (18 seconds) with a combined energy of 510 – that's moderate to strong energy for this spot. The conditions are expected to be good. This is your best chance, but it's over a week away, so treat it as promising but keep one eye on the updates.

The rest of the first week of September is a mix of small, onshore junk and glassy but tiny waves. Nothing else comes close to that Tuesday afternoon window. If you're a beginner, the swell never tops 5ft, so it's fine for learning, but the conditions are pretty average most days. For the few times it goes glassy, it might be worth a paddle, just don't expect much.

All in all, it's a long, quiet spell. Save your energy for that Tuesday the 1st session if it holds.

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.
