The Lowdown

Alright folks, Rusty here. Let's take a look at what's cookin' for Honokohau Harbour over the next couple of weeks. Straight up, it's a bit of a mixed bag, and the first few days are gonna require a little patience.

We start off with some moderate energy in the water, but conditions are just a touch off. Saturday afternoon, the 5th, we've got a 5ft SSW swell with a 12-second period pushing in. The combined energy is sitting at 671 (moderate), and while the wind is light and offshore from the West, the report calls it marginal. The water temp is a balmy 82°F, which is about 2°F warmer than usual for this time of year, so it's a little warmer than average – nice for a long session.

Sunday and Monday offer some size, but the wind angles aren't doing us any favours, keeping things bumpy. The real tease is Monday afternoon, the 7th. That's when we see the swell bump up to 8ft from the WSW, with a 14-second period, giving us a strong 2922 combined energy. The wind is light offshore from the West again, which is promising, but the forecast still rates it as marginal, so keep expectations in check.

After that little pulse, things drop right off. From the 9th of September through to the middle of the month, we're looking at a real flat spell. Swell heights drop below 3ft and the combined energy figures are in the low hundreds or below – really weak. There's a stretch of about a week with nothing worth paddling out for. A few of those days even have clean-ish winds, but there's just no push in the ocean.

We finally see a flicker of life towards the end of the run. Thursday the 17th is the one to circle on the calendar. The swell is still small at 2ft from the SW, but the period stretches out to 16 seconds (a nice long groundswell). The combined energy is 557 (moderate). But the real kicker is the wind: glassy. That's right, dead calm. For a reef break like Honokohau Harbour, that is pure gold. The forecast even says "expect good surf conditions." This is the standout of the entire forecast. The crowds are listed as "sometimes," so you might have a few buddies out, but with that glass, it'll be worth the paddle. It's a long-period swell on a reef, so the sets will be clean and lined up.

The following Friday, the 18th, sees a slight bump in size to 4ft from the SSW, but the wind turns cross-onshore, so the quality drops off again. After that, it looks like we drift back into smaller, marginal conditions for the rest of the outlook.

So, to sum it up: the first week is mostly about waiting out some bumpy, mediocre conditions, followed by a flat spell. The clear winner is Thursday the 17th with that glassy morning and long-period groundswell. Don't sleep on it.

Rusty, signing off.

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.
