The Lowdown
G’day, Rusty here. We’ve got a real mixed bag coming up over the next couple of weeks along this stretch, so let’s break it down.
The early part of the window is pretty flat. Wednesday the 19th and Thursday the 20th are basically write-offs – tiny bumps in the 1ft to 2ft range with poor conditions. Friday the 21st morning shows a glimmer with a 3ft south swell and glassy winds at Akabane Long Beach, but it’s still a bit ordinary, just surfable. That’s really the only flicker of hope in the first week.
Now, things start to build from Monday the 24th with the swell pushing up to 3ft from the south-southwest, but the winds are still messy – cross-onshore and choppy, not doing us any favours. The real change comes Tuesday the 25th. That morning we see a solid jump to 7ft from the SSE with a very long 15-second period – proper groundswell energy. The combined swell energy is strong at 1991. Winds are light cross-shore, so it’s rideable for an experienced surfer, but watch out – waves over 5ft and approaching 7ft are getting into the zone where beginners might struggle, and 7ft that afternoon with onshore winds makes it even tougher. This is a standout for the more skilled crew, but crowds are often a factor here, so get in early.
Wednesday the 26th is where it gets serious – and honestly, too big for most. Swell hits 12ft to 13ft from the SSE with a very long 17-second period, and combined energy is through the roof at 6698 to 7562. Winds are light cross-shore and cross-onshore, but frankly, at this size it’s expert-only territory. Same story Thursday the 27th – 18ft bombs with heavy rain and strong winds, 10363 energy – that’s a beast of a day, only for the brave and experienced. Friday the 28th morning sees glassy conditions and a still-massive 13ft swell from the SSE, but again, this is a big-wave session only.
The second week settles down a bit. Saturday the 29th drops to 7ft from the south with 11-second period, marginal conditions, and then we’re back into a run of poor surf through to Tuesday the 3rd of September. The one real highlight in that later stretch is Thursday the 3rd of September morning – a 4ft swell from the SSE with clean offshore winds out of the NNW, good wave quality expected. That’s your best bet if you’re looking for something manageable and clean, though it’s still only a moderate-sized swell.
Best of the whole window? Tuesday the 25th morning for the experienced crew, and Thursday the 3rd of September morning for a cleaner, more manageable session.
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. 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.
