The Lowdown
Alright, this is Rusty. Let's have a look at what's on the cards for Honokohau Harbour.
Truth be told, the next week and a half is a bit of a struggle. The pattern is flat, small, and messy. We’re looking at a long stretch of poor surf conditions from Friday, July 31st, all the way through to the first week of August. There’s a real gap here with nothing worth paddling out for. The waves are tiny, mostly around 1ft to 3ft, and the wind is either on it or cross-onshore, just making a mess of things. The combined energy readings are all over the place, from weak numbers like 13 (moderate) up to a few hundred, but that doesn't mean quality – it's just a lot of weak, short-period chop. The swell is too short, often under 8 seconds, and just doesn't have any push.
The water temperature at Honokohau Harbour is sitting at 81°, which is about average for this time of year, so no surprises there.
The only real flicker of hope comes on Tuesday, August 11th. The afternoon session at Honokohau Harbour is looking like a proper standout. The combined energy of all swells at that point is a strong 485 (moderate), coming from the SSW at 3ft with a 14-second period. That’s a decent groundswell that’ll have some shape. The real kicker is the wind – it’s glassy. That’s a massive plus. You’ll get clean, lined-up waves with no wind chop. The water will be smooth. It’s a reef break that’s consistent and fairly exposed, so it can handle a bit of energy. The crowds are sometimes a factor, so you might have a few others out, but for that quality, it’s no surprise. The direction from the SSW is a good match for the optimum swell direction here. This is the one to circle on the calendar.
After that, the long-range forecast towards the middle of August shows some larger, longer-period energy coming in from the west, with combined energy readings pushing into the 500s and 600s. The swell heights are around 3ft to 4ft with periods of 12-17 seconds. That’s promising, but it gets a bit more uncertain. The wind remains a problem, mostly cross-onshore and light, which will keep the surface textured. The morning of Monday, August 10th, has a 4ft SSW swell with a 16-second period and light onshore winds – it’s a marginal call, but it's the next best thing after the 11th. The good news is the reef here can handle a longer period swell, so those sets will have some punch, but the wind won't be doing you any favours.
For now, the plan is simple: wait for that Tuesday, August 11th afternoon glass-off. That’s your best bet. Everything else is a flat, windy 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.
