The Lowdown
Alright folks, Rusty here. Let’s break down the surf outlook for Honokohau Harbour over the next couple of weeks. Right off the bat, we’ve got a long stretch of nothing much – the waves are flat, winds are messy, and you won’t be stoked. Patience is the name of the game.
The first real glimmer shows up way down the line. That Saturday the 25th of July morning session has a clean offshore wind from the W at about 6 mph and moderate energy, but it’s still marginal. The absolute standout is Saturday the 25th of July afternoon. That’s the one.
At Honokohau Harbour (Kona), Saturday afternoon serves up a glassy, clean 4 ft SSW swell. The wind goes totally calm – glass – out of the NNW at just 3 mph. That’s the kind of surface you dream about. The swell period is 18 seconds, so we’re talking proper long-period groundswell with plenty of push and shape, and the combined swell energy is a strong 926. This is a reef break, fairly exposed to the WNW, so the SSW direction matches up well. The wave is consistent here, but crowds can show up sometimes, so expect company. Water temp is about 80°, which is 1° warmer than average – a little warmer than usual, nothing crazy.
Before that? From now through most of July, the pickings are slim. Tiny waves, cross-onshore winds, and low quality. There’s a gap of more than a week with nothing good to chase.
Monday the 27th of July afternoon also turns glassy with a 3 ft SSW swell, but that’s really only longboard or funboard territory.
After the 25th, it drops off fast. By the end of July and into early August, the swell shrinks and the winds get messy again. The 1st of August morning shows a little lift (2 ft, 321 energy), but the wind is onshore and the quality just isn’t there.
So keep your eyes on Saturday the 25th of July afternoon – that’s your best shot. Glassy, clean, proper groundswell. The rest of the two weeks? Not much to write home about.
Rusty.

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.
