The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s shaping up for Honokohau Harbour over the next couple of weeks.

We’re looking at a pretty slow start, but there’s a serious window of opportunity coming up if you’re willing to wait for it. The early days are flat, choppy, or just plain messy, so don’t bother rushing out just yet. Patience is the name of the game.

The first real chance to get wet comes Friday afternoon, 4 September. It’s tiny—only 3 ft from the NNE with a short, 6-second period, and the wind goes glassy. It’s surfable, but honestly, it’s pretty ordinary. You’ll scratch around for something fun, but it’s better than a kick in the teeth.

Saturday, 5 September, sees a bump in size. We get 6 ft from the SSW, with a proper 12-second groundswell. The combined energy is moderate (924). The wind is cross-on both morning and afternoon though, so it’ll be a bit choppy. It’s a marginal call, but if you’re desperate, there’s some juice there.

Sunday, 6 September, holds similar size—6 ft to 6 ft from the SW, period stretching to 13 seconds. Energy is picking up to 1580. Still, light cross-on winds keep it from being clean. It’s a bit of a tease.

Now, here’s the standout. Monday, 7 September afternoon. The swell climbs to 10 ft from the WSW with a 14-second period, pumping out a combined energy of 3973. That’s a serious amount of grunt. And the wind? Glassy, just glassy, with a SSW breeze of 3 mph. This is prime for experienced surfers only—anything over 8 ft is expert territory, and this one’s got plenty of power. A long-period groundswell like this works best at a reef setup like Honokohau Harbour, so expect well-shaped, clean lines with long lulls between sets. Crowds are sometimes an issue here, so keep that in mind. This is the best on offer, no question.

Tuesday, 8 September afternoon, settles down to 3 ft from the SSW but with a long 14-second period and glassy conditions. Energy is still solid at 1011. Expect very good, clean surf for a smaller day. Great for intermediates.

After that, the rest of the window drops off hard. From Wednesday, 9 September, all the way through to Saturday, 19 September, it’s mostly small, weak, and onshore. Swells hover around 1.0 ft to 4 ft, periods are all over the place, and the wind is mostly cross-on or onshore. There are a few glassy moments, but the wave heights are pitiful—nothing worth chasing. A long, flat spell settles in.

Water temperature is sitting at 82°F, which is about 1°F warmer than normal for this time of year—nothing to write home about, just a touch above average.

So, to sum it up: Monday afternoon, 7 September is the big one. Get on it if you’re experienced. Other than that, it’s a whole lot of nothing.

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.
