The Lowdown
Alright folks, Rusty here. Let's have a look at what's cooking for the stretch ahead.
Right off the bat, this is a tough outlook. We're looking at a solid run of poor conditions through the first week before things finally start to look up. Akabane Long Beach is our only option in the data, and for a good long while it's just not gonna be worth paddling out.
The first proper window where you might even consider it isn't until Thursday the 20th in the morning. There’s a small 2 ft southerly swell sneaking in with a period of 10 seconds. The wave energy is weak, sitting at just 85 (moderate energy). The big positive here is the wind is glassy, so the surface will be clean. But honestly, it's just "surfable waves but very ordinary conditions". Don't expect much.
Then we go through another dry spell of poor surf until a real glimmer of hope appears on Sunday the 23rd. The morning session sees a 4 ft SSW swell with a period of 9 seconds and glassy conditions due to light westerly winds. The energy is solid at 299 (moderate energy), and the text says to expect good surf conditions. This is the first time it feels worth getting wet.
But the real standout, the one you're marking on your calendar, is Monday the 24th. The morning is shaping up to be the best on offer for a while. A 4 ft SSE groundswell is rolling in with a very long 16-second period. This is quality stuff, with a combined energy of 946 (moderate to strong). The winds are light northwesterlies, making it cross-offshore and clean. This is the one. This will be a proper session with well-shaped, powerful lines, especially if you can find a peak that handles that long-period swell. The afternoon does get a bit bigger at 6 ft with the same period, but the wind goes cross and the text flags it as marginal – so the morning is the call.
Things get bigger and more serious after that. Tuesday the 25th through to the 27th sees solid groundswell in the 7 ft to 12 ft range, with that long 16-second period and massive energy (over 2000 and climbing to 6000+). For the experienced crew only. The standout here is Wednesday morning the 26th: an 8 ft SSE groundswell with glassy winds. The text says "excellent surf conditions for experienced surfers" with a high internal score. That’s huge, but it's big and powerful, so leave the soft-top at home. By Wednesday afternoon and into Thursday, it gets too big for this break, and then the wind turns nasty on Friday the 28th with a strong breeze up to 34 mph, making it completely blown out.
So, to sum it up: the first week is a write-off. Sunday the 23rd morning gives you a small, clean session to get your fix. The best bet is Monday the 24th morning for clean, powerful, long-period waves. For the big crew, Wednesday the 26th morning has the potential to be absolutely pumping with giant, glassy 8 ft groundswell.
Stay patient, wait for that Sunday-Monday window.
Rusty.

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 Akabane Long Beach 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.
