The Lowdown
Alright, Rusty here. It’s a quiet stretch for Honokohau Harbour. We’re looking at a run of flat, onshore days right through the end of the week. The water is a warm 80°, which is pretty normal for this time of year, so no surprises there.
The first few days – from Sunday the 19th through to Thursday the 24th – are a total bust. The swell is tiny, around 1ft to 3ft, and the wind is mostly cross-onshore. It’s just messy, weak, and not worth paddling out. The combined energy is low, barely cracking 28 (28) on Sunday morning, so you’re just burning energy.
Friday the 24th morning is where things get interesting. We’ve got a glassy clean start, with a light 2ft SSW swell and a period of 18 seconds. That’s a nice long groundswell, and the combined energy jumps to 376 (376) – a solid moderate push. The wind is almost nothing, just a slight air, so the surface is smooth. It’s not huge, but for a reef that’s consistent, this is the best on offer. The swell direction is SSW, which is right in the pocket for optimum WNW exposure at Honokohau Harbour. Crowds are sometimes a thing here, so keep your eyes peeled.
The real standout, though, is Saturday the 25th morning. Another glassy start, clear skies, and the swell bumps up to 2ft at 20 seconds – that’s proper groundswell. The combined energy hits 866 (866) – a strong, powerful push for that size. The conditions are pristine: glassy, clean, and that long period will wrap beautifully around the reef. This is the pick of the entire forecast. The caveat is that long period can make it break a bit straight on a beach, but at a reef like this, it’s a dream. This is the one to circle if you’re an intermediate.
After Saturday, the swell sticks around in the 2ft to 3ft range through the end of the month, but the wind turns more onshore or cross-on, and the quality drops. There’s a brief window of glassy conditions again on Wednesday the 29th afternoon, but with only 2ft at 13 seconds, it’s just ordinary. Not worth a special trip.
The first week of August looks like more of the same: small, onshore, and marginal. The combined energy sits around 200 to 400 (200-400), but without clean wind, it’s a slog. The best bet is to wait for that Saturday the 25th morning window. It’s a glassy, long-period groundswell that’s going to make Honokohau Harbour look like a proper reef break. Get on it.
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.
