The Lowdown
G’day, I’m Rusty. Let’s talk about the surf outlook for the next two weeks. We’re looking at Honokohau Harbour (Hawaii) – a reef break that’s consistent and fairly exposed to WNW swells. Right now, the water’s sitting at 82°, which is about a degree warmer than usual for this time of year – a nice surprise for the skin.
The first week is a bit of a struggle. There’s a long gap of nothing worth paddling out for from Tuesday the 11th right through to the end of the following week. The first few days are all marginal or poor, with small swell and only a few moments of glassy or clean conditions, but the wave heights are just too small – mostly 2ft to 3ft – and the combined energy is weak. Monday the 17th afternoon has a spike to 4ft from the NNE with a cross-shore wind, but it’s still a marginal call. Honestly, you’re better off waiting.
The real standout comes in the second week, around Monday the 24th and Tuesday the 25th. On Monday morning, we’ve got a solid 3ft SSW groundswell with a very long period of 18 seconds, combined energy climbing to 685 (moderate), and the wind is light offshore from the WSW. That’s clean, glassy-ish conditions with a long-period swell that’s best for a reef like Honokohau. By Tuesday the 25th morning, the swell nudges up to 4ft from the SSW, period 15 seconds, and energy at 856 (strong). Again, offshore wind from the WNW keeps it tidy. Keep in mind, this is a long-range call – promising but not locked in yet. The tide might be a factor, so keep an eye on that.
The rest of the second week drops off again, with small, weak swells and poor conditions. For now, the window is narrow but worth a shot if you’re keen.
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.
