The Lowdown
Alright folks, Rusty here, checkin’ in. It’s one of those outlooks where patience is the name of the game. Things are looking mighty quiet for a good stretch, so let’s break it down.
Right now, we’re looking at a dry spell at Honokohau Harbour. This reef setup is fairly exposed to the swell, but the energy is just not getting in here properly. The first few days, starting Friday the 11th, the conditions are pretty grim with poor surf, wind ripples, and tiny 1ft to 2ft swell. The water is sittin' at a comfortable 82°, which feels a touch warmer than normal for this time of year.
There’s a long gap here with no real surf to get excited about. From the 11th all the way through the 14th, you’re lookin’ at waves so weak they’re barely registering. The combined swell energy is low (between 86 and 261), which tells the story – not much push. The wind is mostly light and either onshore or cross-onshore, which kills the shape on a reef.
Things start to show a tiny pulse of life from Monday the 15th to Thursday the 18th. It’s still only marginal, but the swell height creeps up to 3ft, and the combined energy starts to climb into the mid-400s and hits 503 on the 18th. The period is nice and long though, between 17 and 22 seconds – that’s proper groundswell energy, which means longer waits between sets and cleaner lines if it holds. The wind stays light, mostly offshore or cross-on, so the face could have some potential, but the size is just too small for the reef to really be worth paddling out for.
After that, it fades out again. Around the 22nd, the energy drops completely – 42 and 19 combined energy on Tuesday – so that’s a dead zone. The one little glimmer comes on the 23rd, Wednesday morning: glassy conditions with a 2ft, 17-second swell pushing in from the SW, and a combined energy of 176. It’s surfable, but you’re scratchin’ for tiny waves. It’s just too inconsistent to call it a goer.
Further into the last week, from the 24th to the 26th, the energy comes back to the 250–475 range, but the wave comment keeps sayin’ marginal or poor. The swell direction is all over the shop, and the wind is back to cross-on or onshore. Not the kinda rollin’ that gets the heart pumpin’.
If you are an absolute die-hard longboarder who just wants a glide, maybe that Wednesday morning 23rd is your only window. But honestly, this setup looks more interesting for a kite surfer than a paddle surfer for most of the forecast. There ain’t enough power in these small, slow pulses to do much on a shortboard.
So, the honest truth? There’s no real standout here. That 23rd morning is the only date that pops up with glassy wind, but the wave itself is tiny. For the rest, it’s a whole lot of waiting. Sometimes it be like that in this region. Forecasts can change, but for now, keep the stick in the car and maybe bring a towel for a swim.

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.
