The Lowdown

Alright, Rusty here. Let’s get into what’s brewing for the next couple weeks.

First up, we’re looking at a slow start. There’s no real swell to speak of until the middle of the week. The surf through Thursday the 18th is mostly small, with cross-onshore winds making it feel even worse. Swell heights are usually under 3ft, with periods all over the place and combined energy readings in the hundreds, but the wind is just not your friend. It’s a bit of a flat spell to start.

The first decent window shows up Wednesday afternoon the 16th. Honokohau Harbour (Big Island) sees 0.8m (about 3ft) of SSW swell with an 18-second period, and the wind turns glassy. That’s clean, even if the size is small. Combined energy is 474, which is fair for the size. It’s a reef, so you need to be on your game, but the glassy surface is a huge plus. Water temperature is 28°C (82°F), a touch warmer than usual.

After that, we go through another patch of average conditions for several days. Not much to write home about until Friday the 25th afternoon. Swell from the WNW at 0.6m (2ft), 21-second period – that’s a proper long-period groundswell – and it’s glassy again. Combined energy hits 491. The long period will push through nicely on the reef, giving clean, long lines. Not big, but quality.

But the real standout is Saturday the 26th afternoon. Again Honokohau Harbour. Swell 0.8m (3ft) from the WNW, 17-second period, and glassy. Combined energy jumps to 795 – strong for the size. The waves will have real push and shape. This is your best bet for the entire run. It’s an intermediate reef, so crowds are possible, but for anyone looking for clean, well-formed waves, this is the session. It’s a promising call, over a week out, but the signs are good.

So, bottom line: don’t rush out before the 16th. Wednesday the 16th afternoon is a small but glassy option. Friday the 25th afternoon is a nice, long-period glass-off. Saturday the 26th afternoon is the clear standout – mark 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.
