The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer for Honokohau Harbour over the next couple of weeks.

Right off the bat, I gotta tell ya, it’s a pretty slow start. We’ve got a long stretch of small, weak, and messy waves ahead. The first solid week is mostly a write-off. The water temperature is sitting at a touch warmer than normal for this time of year, about 82°, so at least it’ll feel nice floating around.

The first proper session that’s worth getting excited about doesn’t roll in until Tuesday the 25th. That’s a good eight days away. Tuesday afternoon, Honokohau Harbour looks like it might fire up for a bit. The wind goes glassy – that’s a big positive – and the combined swell energy is pumping at a solid 305. It’s a small wave though, around 2ft coming from the SSW with a period of 15 seconds. That’s a long-period groundswell, which means it’ll have some nice shape and energy, but for a reef setup like this, it might be a little weak to really get the barrels going. Still, glassy conditions and a bit of swell is the best we’ve seen all forecast. The crowds are listed as “sometimes”, so it’s not a guarantee you’ll have it to yourself, but you should find a few.

After that, it’s back to meh. The next best look is Sunday morning the 30th. The wind goes totally calm, glassy conditions again, but the wave is tiny at 1ft with a combined energy of 129. It’s barely surfable, but you might get a couple of fun little rides on a log.

Late in the run, there’s a total blank. From Tuesday the 1st of September onward, it’s just flat or junk. The combined energy drops to almost nothing – a reading of just 2 on the 1st – and the swell is tiny or from the wrong direction. Not much hope there.

Overall, it’s a lean couple of weeks. The standout is definitely that Tuesday afternoon on the 25th if the glassy winds hold. Don’t get your hopes up for much else.

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.
