The Lowdown
Alright, let’s get into it. Over the next 16 days, Honokohau Harbour is serving up a pretty mixed bag. There’s no standout stretch of amazing surf, but there are a couple of brief windows where conditions line up. For the most part, you’ll be waiting for those rare moments of glassy, clean water.
The first few days are a write-off. Monday August 31st and Tuesday afternoon are choppy and cross-onshore, with small, weak energy. Monday morning has a mere 2 ft of swell from the SW with a very long 15-second period, but it’s messy and only 210 combined energy – that’s weak, honestly. Not worth paddling out.
Then, on Tuesday morning, September 1st, we get a real glimmer. The wind goes glassy, with a 3 ft SSW swell and a super long 18-second period. The combined energy jumps to 646 (moderate), and the water temp is a comfortable 82° – about average for this time of year. That long-period groundswell will wrap in nicely at this reef break, offering clean, lined-up waves. It’s a consistent spot, so you can expect a few waves. This is the best session of the whole forecast, hands down. But be aware, with that long period, the sets might be a little inconsistent, and it could be a bit fat on the inside. Still, for a Tuesday morning, it’s a winner.
The rest of the first week? Not great. Wednesday through to the following Monday are plagued by onshore and cross-onshore winds, with small, short-period NNE swell. The energy is mostly weak to moderate (between 88 and 377), and the wave comments are all “poor surf conditions.” There’s a slight uptick on Saturday, September 5th, with a 4 ft SSW swell and 10-second period, but the wind is onshore or cross-onshore, and it’s rated as marginal at best. On top of that, Saturday afternoon has rain showers.
The second week is a bit of a grind. Sunday, September 6th, through to Tuesday, September 15th, sees mostly small SSW swell (1 ft to 4 ft), with moderate to strong combined energy values (up to 762) but the wind is almost always cross-onshore or onshore. There are a couple of near-glassy moments on Thursday, September 10th afternoon, and Monday, September 14th morning, but with swell under 2 ft, it’s barely surfable. The energy is moderate (144-312), but the waves will be small and weak. Not really worth getting excited about.
Overall, the only real standout is Tuesday morning, September 1st. After that, it’s a long wait for clean conditions that just don’t arrive. If you’re desperate, check the marginal windows on September 5th morning or September 7th afternoon, but keep your expectations low. This is a reef break, so it can handle bigger swell, but the wind is the enemy here.

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.
