The Lowdown
Ah, Hakalau. Look, I’m gonna be straight with you. The next week and a half is a bust. Just flat, weak, and onshore. We’ve got a long stretch of poor surf starting Tuesday the 4th and running all the way through to the 14th. The swell is tiny, mostly under 5ft, and the wind is coming from the east, which is cross-on or onshore for this spot. It’s not gonna be pretty. The water temp is sitting at 80°, which is about normal for this time of year, so at least you won’t need a hood.
The energy is weak, with combined swell energy in the low hundreds for most of that first week. It’s just not doing anything. You’re looking at light breezes and small, ripply conditions. Not worth the paddle.
Then, around the 15th of August, things start to rumble. The swell finally pushes up, but it’s coming with a lot of east in it, and that’s still putting us in a cross-onshore position. The wave energy starts to climb big time – we’re talking 1049 on the 15th, then 1309 on the 16th, and by the 17th it’s over 2000. That’s proper energy, but the wind is still messing it up. It’s gonna be a choppy, bumpy mess. And the period is short, around 8-10 seconds, so it’s not going to have any real push or shape to it. This is more for the kite crew than us paddle surfers.
Honestly, the only faint glimmer of hope is the 18th. We see the swell drop to 7ft, the wind eases to a light onshore, and the energy is still strong at 1345. But even then, it’s got that east in it, and the period is still short. It’s marginal at best. The 19th continues to fade. So, there’s nothing here that’s a standout. It’s a long, blank run. But hey, that's Hakalau for you. It’s fairly consistent, so this kind of flat spell isn’t the norm. Forecasts can change. Keep an eye on it.

Information about the Hakalau Surf forecast
The above surf forecast table for Hakalau provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Hakalau can be found by selecting the local surf guide option on the grey menu. Our Hakalau 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 (Hakalau) 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 Hakalau 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.
