The Lowdown

Alright folks, Rusty here. Let's have a look at what Akabane Long Beach has in store for us over the next couple of weeks. It's a bit of a slow grind for a while, but there's a serious payoff coming if you can be patient.

Right now, we're looking at a pretty grim run. For the first week, from Thursday the 13th right through to Wednesday the 20th, the conditions are just not cooperating. We've got a lot of onshore and cross-onshore wind, and the wave quality is pretty poor. The swell energy is weak to moderate for most of this time, with readings like 211 (moderate energy) popping up on Thursday morning, but it's all wind-affected and choppy. You'll see small waves around 3 ft to 4 ft, but it's not the kind of surf you want to paddle out into unless you're desperate. That's a solid week of nothing special.

The water temp is sitting at 82°, which is bang on average for this time of year, so no surprises there in terms of needing a spring suit.

Finally, things start to turn around on Thursday the 20th. Thursday morning we get a real surprise – glassy conditions with a light NNW breeze. The swell picks up to 4 ft from the S, with a period of 8 seconds and moderate energy (212). It's not going to be world-class, but after a week of rubbish, a clean, glassy wave is a welcome sight. This would be your best bet for a quick surf before the wind swings around again in the afternoon.

We then have a bit of a quiet spell until the real standout event arrives. On Saturday the 22nd, the afternoon session looks promising again – glassy conditions with a 3 ft SSW swell and a 10-second period, energy at 214. Nice and clean.

But the real gold is on Sunday the 23rd, Monday the 24th, and Tuesday the 25th. This is the big one. Sunday morning the 23rd, we’ve got glassy conditions with a solid 5 ft swell from the SSE, a very long period of 15 seconds, and a whopping combined energy of 1136 – that’s powerful, strong energy. This is excellent for experienced surfers. The long period will make for some proper groundswell lines, so the reef and river setups would handle it beautifully, but at a beach break it might close out a bit.

Monday the 24th looks even bigger. Morning is glassy again with a 8 ft SSE swell, a 15-second period, and 2588 energy. This is getting into expert-only territory. The afternoon holds 8 ft with a 16-second period and 3296 energy – massive. By Tuesday the 25th, it's predicted to be 10 ft from the SE, with 14-second periods and 3142 energy, but the forecasts are calling it too big for this break (wind and tide favorable, but the swell is predicted to be too big for this break). That's a bit of a caveat – at that size, Akabane might be maxed out and dangerous.

So, for the standouts: Sunday morning, August 23rd and Monday morning, August 24th. These are your windows. Glassy offshore winds, powerful groundswell, and serious size. Sunday is the sweet spot for advanced surfers, while Monday is pure big-wave territory. Just be aware that with this much energy, Akabane Long Beach can get a bit of a crowd, as we know it can get "often" busy.

After that, the swell drops back down through the 26th and 27th, and we're back to poor conditions with nothing worth chasing.

That's the long and short of it for Akabane. A long wait, but a couple of really special days on the horizon.

Rusty.
