The Lowdown

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

Right off the bat, I gotta be straight with you – the next week and a half is looking pretty grim. We’re staring down a long stretch of poor conditions with only a few barely rideable windows. The water is sitting at a warm 80°, which is about average for this time of year, so at least you won't need a thick wetsuit.

The first real chance to get wet comes on Saturday morning, July 18th. We’ve got a tiny 2ft swell from the SSW, but it’s a long-period groundswell at 14 seconds, which is nice. The wind is light from the West, blowing straight offshore, so the surface should be clean. The combined energy is moderate (350), but the wave comment says "marginal surf forecast," so don't expect much. It’s a picky little window.

The next few days are a write-off. Sunday the 19th through to Tuesday the 22nd are all "poor surf conditions" with either cross-onshore winds or tiny, messy swell. Not worth your time.

Things start to tick up a bit around Wednesday morning, July 22nd. The swell jumps to 2ft but the period goes massive – 24 seconds! That's a proper long-period groundswell. The energy is strong (474), and with a light offshore wind, it could be clean. The score is still low, but this is the most interesting day in the first week. Wednesday afternoon gets a bit bigger with 2ft and a 23-second period, energy hitting 584. The wind switches to a light cross-onshore, but it's still a possibility.

The real standout, and the one I’d circle on your calendar, is Saturday, August 1st. The morning is calling for glassy conditions with a light offshore wind from the WNW. Swell is a tiny 2ft from the SSW with a 15-second period, so the energy is moderate (302). The comment says "expect good surf conditions." For a spot that's been struggling, this is your best bet. It’s a reef break, so that long-period groundswell will wrap in nicely. Crowds are listed as "sometimes," so you might have a few others out, but nothing crazy.

The second week is pretty quiet. Sunday, August 2nd has a small 3ft swell from the West, but the wind is a light cross-onshore, so it'll be a bit bumpy. Everything else in the second week is either poor or marginal.

So, to wrap it up: don't hold your breath for the next week. If you're desperate, try the Wednesday morning, July 22nd session for the novelty of that 24-second swell. But the real winner is the Saturday, August 1st morning. Mark it. Expect clean, glassy conditions on a small but long-period groundswell.

Rusty.

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.
