The Lowdown
G’day, Rusty here. Lookin’ at the next 16 days for Honokohau Harbour, and I gotta be straight with ya – it’s a bit of a mixed bag, not a lot to get truly stoked about. The reef setup here is fairly exposed to the swell, but the conditions are gonna be a real fight for most of the run.
The first few days, from Saturday the 5th through to Tuesday the 8th, we’ve got some size in the water, but the wind is a problem. It’s mostly cross-onshore or onshore, which is gonna leave it fairly choppy and messy. The combined swell energy is moderate to strong, sittin’ around 902 to 2041, so there’s definitely power there. Swell heights are between 6 ft and 7 ft from the SSW, then swingin’ to the WSW and W, with a period of 11 to 13 seconds – that’s mid-range groundswell, so some shape but the wind is just gonna butcher it. The water temp is about average for this time of year, so nothin’ to write home about there.
Honestly, the best of the lot is lookin’ like Sunday the 7th. The morning has a 6 ft swell from the SW with a 13-second period, and light onshore wind. The afternoon is a bit bigger at 7 ft from the WSW, but the wind goes cross-onshore from the NNW. It’s still our best shot, but it’s a “best of a bad bunch” situation – not a standout by any stretch. The surf quality is always gonna be marginal, and the break is consistent, so it’ll be breakin’, but it ain’t gonna be pretty. Crowds are possible here, so expect a few heads out.
Then after the 8th, it takes a real nosedive. From Wednesday the 9th right through to Sunday the 20th, the swell drops right off. We’re down to 1 ft to 4 ft, with combined energy droppin’ to under 600 – weak, weak stuff. The period is all over the place, from a short 6 seconds up to a very long 21 seconds, but with no size, that long period just means lines with no push. The wind is a mix of onshore and cross-onshore, makin’ it even less appealing. There are a few glassy moments on the 13th and 14th, but the swell is tiny (3 ft to 3 ft) and short period, so it’s just ankle-biters. This is a long gap of poor surf that stretches from the 9th all the way to the end of the forecast.
So, to sum it up: the window is open for a few days at the start, but it’s gonna be a messy, choppy grind. Don’t expect any magic. If you’ve got an itch to paddle, maybe Sunday the 7th is worth a look, but leave the expectations at home. The rest of the run is a write-off.
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.
