The Lowdown
Right, Rusty here from Akabane Long Beach. Gotta be straight with ya: the first week and a half is a write-off. Small, weak windswell, and that lumpy onshore wind has the place looking like a washing machine.
The one real moment to get excited about is Tuesday the 25th of August first thing. We've got glassy, flat-calm conditions and a chunky 10ft swell rolling in from the SSE with a long 15-second period. That's big, powerful groundswell (combined energy of 3840). For this beach, 10ft is expert-only territory. The waves will be thick and heavy. If you're not a seasoned pro, stay on the sand. The same swell hangs around into the afternoon, but the wind swings onshore and takes the shine off.
There’s a minor window the morning of Sunday the 23rd—glassy conditions on a tiny 3ft SSW swell (combined energy of 199). It’ll be clean but small. Good for a log or a slow morning, nothing more.
Everything else is small, choppy, cross-onshore, and not worth suiting up for. A couple of bigger swells show up in the second week (like 6ft on the 24th) but the wind is all wrong and it just gets messy.
If you’re experienced, set the alarm for the 25th. That’s the real deal. Everything else is a pass.
