The Lowdown

Alright, Rusty here again, let’s break this down in feet and Fahrenheit so you don’t have to do the math.

First off, the water’s sitting around 82°F, which is about 2°F warmer than average for this time of year – feels real nice and tropical.

The start of the period is a total bust. From Wednesday 9th September right through the weekend, the swell is tiny, the wind is mostly cross-onshore, and the wave energy, while moderate in numbers, isn’t giving us anything rideable. Everything is marked as “poor surf conditions.” You’re looking at at least four or five days of flat, bumpy ocean. A slight flicker on Sunday the 13th afternoon – glassy conditions with a light breeze, a tiny 1ft swell from the southwest. The report calls it “surfable but very ordinary.” That’s a 1 out of 10. Not much more than a pool session.

Monday the 14th and Tuesday the 15th don’t bring any real change. The swell stays small, wind is light but not helpful. The wave energy bumps up a bit on Tuesday afternoon, but with a 2ft swell, it’s all just push and no shape.

The highlight of the entire 16-day run is Saturday 19th September in the afternoon. The wind goes glassy, dead calm, and we’ve got a 2ft southwest swell with a 16-second period. That’s a proper groundswell. The combined energy is moderate (339), and the report says “expect good surf conditions.” For a reef break like Honokohau Harbour, that long period will make it line up nicely. The direction isn’t a perfect match for the optimum (WNW), but the clean conditions more than make up for it. It’s small enough for everyone, but the spot has a reputation for being consistent, so you should get a few. Just remember, it can get a bit crowded there.

That Saturday arvo window is your best shot. After that, it’s back to small, onshore slop right through to the 24th. Not much else worth paddling for, but that one session could be worth the wait.

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.

Honokohau Harbour is 99 km (61 miles) from Hilo. If you plan a vacation in Big Island, look for hotels and other accommodation in Hilo. Hilo has rooms for a wide range of budgets as well as car hire and transport links.
