Table - best surf conditions forecast for Hakalau over the next 16 days.
Alright, this is a tough one to call. Look, I'm looking at the whole 16-day window for Hakalau, and honestly, it's a bit of a bummer. The data shows a long stretch of poor conditions. There's a gap from now all the way through to the end of the month with no real standout sessions. The only time the score even nudges up is on Sunday the 12th in the morning, and even then, it's just a marginal call.
The main issue is the wind. It's almost constantly onshore or cross-onshore, which is going to make for choppy, crumbly waves. The swell direction is mostly from the ENE, which is the optimum for this spot, but the quality just isn't there. The water temp is sitting at 80°F, which is about 1°F warmer than normal for this time of year, so it's a touch on the warm side.
Let's break it down. Friday the 10th and Saturday the 11th are a write-off. The swell is there, around 4ft to 6ft, but the wind is on it, and the energy in the water is weak. It's just messy.
On Sunday the 12th, the morning actually shows a bit of a pulse. The swell jumps to 8ft from the ENE, with a period of 8 seconds. The combined energy is a solid 1245, which is a lot of power. But here's the kicker: the wind is still onshore at 12 mph. For a river break, onshore wind and a beach-break setup can mean it's more interesting for kite surfing than for a clean paddle session. It's going to be a bumpy, drifty mess. That 8ft is also getting into the size that's only for the experienced crew.
The rest of the week and into the second week is more of the same. The swell drops, the wind stays shifty from the ESE and ENE, and the scores stay at zero. The wave energy is mostly moderate, but it’s never clean. Even on the 23rd, when the wind is light and the swell is small, it's still only a marginal call.
To be honest, there's no standout here. If you're desperate, the Sunday morning of the 12th offers the most size, but you'll be fighting the wind. For the rest of the period, you're better off waiting for the next system. It's a rough run, but forecasts can change, so don't lose all hope.

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.
