The Lowdown

Alright, my friends, Rusty here. Let's break down the surf situation for the next couple of weeks at Honokohau Harbour. It's a bit of a tale of one great session and a whole lot of waiting.

The first chance to get out is this Monday afternoon. The morning is a bum steer with light, crummy onshore wind. But Monday afternoon, the wind goes totally glassy. That's your window. We've got a solid 6ft groundswell coming from the SW with a long 14-second period, packing some serious energy (2169). The water is about 82°, which is a touch warmer than average for this time of year—nice and comfortable. The glassy wind means the surface will be like a mirror. This is the real highlight. But look, it's a reef break, and 6ft is pushing into expert territory. This is for the crew who know the reef, not the beginners.

After that, the outlook gets stale fast. Tuesday morning, September 8th, the wind howls out of the south at 15 mph, trashing the surface on a 8ft swell. It’s a mess. Then we hit a long dry spell. From Tuesday afternoon all the way into the middle of the month, the swell drops under 3ft, and the energy readings are low, mostly under 400. The wind is a mix of light, onshore breezes, leaving the ocean textured and small. There’s a long gap of days where you’re better off doing something else.

We get a small reprieve on Thursday the 17th. The afternoon goes glassy again with a clean 3ft SSW swell. It's small, but the combined energy pops to 544, so there's a bit of life. It’s a fun, small-wave day. The 19th and 20th also show glassy afternoons, but the swell is a tiny 3ft and 2ft. Surfable, but nothing to write home about.

So here’s the call: the one standout is Monday the 7th, with a solid 6ft SW groundswell and perfect glassy conditions. Get it while it’s good. After that, keep an eye on the 17th, 19th, and 20th for small, clean waves. Crowds are something to watch for here. Make the most of that first window.

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.
