The Lowdown

Alright, Rusty here again. Let’s talk about Honokohau Harbour in feet and miles per hour.

So, the start of the 16-day window is pretty quiet. A lot of poor surf conditions through the first few days of September. Not much to get excited about until the 5th.

That Saturday, September 5th, we finally see something worth paddling for. Swell comes up to about 5 ft from the SSW with a 12-second period. The combined wave energy is moderate (626). Light onshore wind keeps it rideable for the intermediate surfer. The water temp is about average for this time of year. The swell direction matches the optimum for the break, which is always a plus. Crowds can show up sometimes, so you might have company.

Sunday the 6th keeps it going with 5 ft to 5 ft swells from the SW, periods around 11 seconds. The energy builds to 952 by the afternoon – a solid moderate push. Light cross-onshore wind puts a bit of ripple on the face, but it’s still surfable.

The highlight of the whole outlook is Monday, September 7th. Swell hits 5 ft to 6 ft from the SW with a 13–14 second period – that’s real groundswell energy. The combined energy jumps to 1616 and then 1840, which is strong. The wind is light and onshore, keeping the surface clean for a reef break. This break is consistent, so you’ll get waves. The size is manageable for a confident intermediate. Crowds are possible, so get there early.

Tuesday the 8th sees the biggest swell of the window – 8 ft from the WSW in the morning. That’s expert-only size, especially with a 14-second period and energy at 3760. Light cross-onshore wind early, but a moderate cross-shore breeze and chop kick up in the afternoon. If you’re experienced, the morning could be your window.

After that, it drops off quickly. From the 9th on, it’s mostly poor to marginal conditions with small, weak swell. Friday the 11th afternoon has a little 2 ft clean wave with a 15-second period, but the energy is low (139) – just not enough push for a good session.

From the 12th through to the 17th, it’s poor conditions, small swell, and cross-onshore winds. A long stretch of flatness with no real recommendations.

Best bet: Monday, September 7th at Honokohau Harbour. That’s your standout – solid SW groundswell, clean, strong energy. The 5th and 6th are decent seconds. The rest is a waiting game.

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.
