The Lowdown
Alright, Rusty here. Let’s talk about what’s on offer for the next couple of weeks. First up, we’re at Honokohau Harbour (Big Island). Water temp is 80°F – that’s just about average for the season, nothing out of the ordinary.
The first week is a write-off, to be honest. From Thursday the 23rd through the end of July, we’ve got a constant feed of SSW swell, but it’s tiny – between 2ft and 4ft. The problem is nearly every session has that cross-onshore breeze, ruining the surface. There’s some long-period groundswell in there, with periods up to 20 seconds on the 23rd and 24th, which usually means good shape, but the wind direction just doesn’t work for this spot. The Thursday afternoon on the 23rd had a 3ft wave with a light onshore, but the comment says it’s marginal. Not worth it.
From Monday the 27th afternoon, things go downhill fast. Wind picks up, swell stays in the 2ft to 3ft range, and the energy drops. We’re in a poor stretch. The Harbour is consistent, but with those conditions, it’s just choppy and messy.
The one true standout, and honestly the only surf you should consider, is Sunday the 2nd of August. That morning is looking sweet – glassy conditions, no wind, with a small 1ft swell from the SW and a 14-second period. The combined energy is low at 100, but it’s clean. The report calls it “surfable but very ordinary” – but in this quiet stretch, that’s your best bet. The afternoon is also glassy. For a beginner, that’s perfect. For anyone else, grab a longboard.
After that, from Monday the 3rd of August, it’s back to junk. Tiny wind swell from the NNE on the 3rd with a 6-second period – that’s just wind chop. Then it’s weak SW and SSW pulses in the 1ft to 2ft range, all with some kind of onshore or cross-breeze. Energy stays in the 100-200 range.
So what do we have? A big gap from the 23rd to the 2nd of August with nothing good. That Sunday the 2nd is your only play. The forecasts after that show a little more energy on the 5th to 7th, but the wind still looks iffy. It’s a slow spell, but forecasts can change.
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. 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.
