The Lowdown

Alright, let’s talk about Honokohau Harbour for the next couple of weeks. This is a reef break that’s fairly exposed to the swell and likes a good west-northwest groundswell. The water temp is about normal for this time of year.

Right now, on Monday the 31st of August, it’s looking rough. The morning has a tiny 2ft swell from the southwest with a long 15-second period, but the energy is weak (217) and the conditions are poor. The afternoon glass-off brings a 3ft north-northeast swell, but the period drops to 8 seconds and the energy is low (91). It’s surfable, but nothing special.

Tuesday the 1st of September is more of the same: small, short-period swell and onshore or cross-shore winds. Wednesday the 2nd and Thursday the 3rd don’t offer much, though Thursday afternoon goes glassy with a 4ft north-northeast swell, but it’s short-period and messy. Energy is still low (110).

Friday the 4th and Saturday the 5th are poor, with onshore winds and small, confused swell. Then Sunday the 6th of September has a real standout in the afternoon: glassy conditions with a 2ft swell from the south-southwest, but the period is a massive 19 seconds. The combined energy jumps to moderate (530), and it’s “expect good surf conditions.” That long-period groundswell will wrap in nicely at this reef, giving clean, well-shaped waves. Crowds are sometimes here, so you might have a few others, but this is the session to target.

Monday the 7th of September morning is messy with a cross-shore breeze, but the afternoon is a beauty—cross-offshore wind, 4ft south-southwest swell at 16 seconds, and strong energy (886). This is another top pick: clean, powerful, and the swell direction is dialed in for the reef. After that, it fades. Tuesday the 8th and Wednesday the 9th are poor, with onshore and cross-onshore winds. Energy drops into the moderate range (654 and 426), but the wind ruins it.

For the second week, from the 10th of September onward, it’s a long dry spell. Thursday the 10th is small and choppy, and through the 11th to the 15th of September, the swell drops right off. The 11th afternoon goes glassy with a 2ft southwest swell at 15 seconds, but it’s weak (189) and just ordinary. The rest of the period is consistently poor, with tiny swells and onshore winds. Nothing worth chasing—just a long stretch of flat to small, messy conditions.

The best bets are the afternoon of Sunday the 6th of September with that glassy, long-period swell, and Monday the 7th afternoon with clean, strong waves. Those are the ones to circle on the calendar.

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.
