The Lowdown
Alright folks, Rusty here. Let's get into it.
This is a strange one for Akabane Long Beach. We're looking at a classic case of "wait for it." The first week and a half is a real mixed bag of small, weak, and mostly messy conditions. The first proper surf worth getting excited about doesn't show up until Tuesday the 11th.
Monday the 10th starts things off flat and choppy with a weak 4.3ft swell from the ESE, period around 12 seconds, and a cross-on breeze that just chops it up. Forget it. Then, Tuesday morning the 11th offers a glimmer with a cleaner 3.6ft E swell (10-second period) and a solid offshore NW wind at 15 mph. The water is sitting at a warm 81°F, which is pretty normal for this time of year. It's a small window, but those offshore conditions will make it clean. The energy is moderate (506). Wednesday and Thursday are write-offs with building onshore winds and dropping swell. Friday the 14th morning looks okay with a clean 3ft E swell (11-second period) under light offshore winds, but don't expect much.
The real standout hits on Saturday the 22nd of August. After a long, dull run, we finally get some proper size. The morning session looks prime: a 5.6ft S swell (13-second period) with glassy, no wind conditions. The combined energy is strong (991). This is a long-period groundswell, so it'll be better shaped with good power, but at a beach break like this, it might be a bit straight. Still, glassy conditions and decent swell are hard to argue with. This is the one to circle.
Sunday the 23rd holds a similar 5.9ft S swell (12-second period) under clean cross-offshore winds, keeping it manageable. Monday the 24th morning sees the swell drop slightly to 4.9ft S (11-second period) with light cross-shore winds and very high energy (1179). It's a good run of surf to end the forecast, though the winds are not quite as perfect as that glassy Saturday.
Overall, this spot has a long dry spell before a powerful finish. The first week is a write-off, but the final week from the 22nd onward offers the best chance of a proper session. Keep an eye on that Saturday the 22nd.
