The Lowdown
Alright, surf fans, Rusty here. Let’s get straight into it. The next couple of weeks look pretty challenging, with only a couple of windows that are truly worth getting wet for. We’ve got a long stretch of nothing at the start, then a few flashes of quality before things get messy again. Let’s break it down.
The run starts out flat and poor. Through the end of August and the first couple of days of September, there’s just nothing happening at Akabane Long Beach. On Monday afternoon, we're looking at a messy 4ft of wind-blown ESE slop with a fresh cross-onshore breeze. That’s a no-go. Tuesday and Wednesday stay poor, with weak, choppy conditions. The swell is there, but it’s short-period and junky, and the wind is just ruining any chance of a clean wave. You’ll be fighting it the whole time.
Finally, there’s a change on Thursday the 3rd. A light offshore wind kicks in by the afternoon, cleaning up a small, 3ft south swell. It’s not big, but the period is a bit longer and that offshore wind will be a big positive. It’s surfable, but very ordinary. This is the kind of day you go out just to get wet, not for the waves of the year. Then, Friday the 4th brings a bit more size, but the wind swings around and it gets messy. A solid 6ft of east swell shows up with heavy rain and a fresh breeze. Not worth it.
Now, Saturday the 5th is interesting. There’s a jump in energy, and by the afternoon that swell is pushing 7ft from the east, with 9-second period. The combined energy is strong, just over a thousand. But the wind is cross-onshore, making it lumpy and choppy. It’s powerful, but it’s a wrestling match. That trend continues into Sunday the 6th, with the swell building to a solid 10ft by the afternoon. That’s big. The combined energy is up over 1600, and the period has stretched out. The wind is light, which helps, but 10ft at this beach is starting to close out and just becomes a washing machine. It’s too big for most, and even for the experienced guys, it’s a handful.
Monday the 7th is the day. This is your standout. We’ve got a 7ft ESE groundswell with a longer 10-second period, light offshore north wind, and the water is glassy clean. The combined energy is over a thousand, and it’s all working. This is the best conditions we see all week. It's still a decent size, 7ft, so that’s for the advanced crew, but it will be clean and powerful. The afternoon, though, jumps back up to 10ft with an onshore south wind, which ruins it.
After that, it seems to fade. Tuesday the 8th offers a brief, clean, glassy morning with a small 3ft swell. That would be a fun little session if it wasn't for the drop in size. By the afternoon, it’s junky again. Wednesday the 9th is another marginal day, with a bit more size but a cross-onshore wind.
Then the bottom falls out. From Thursday the 10th, the wind howls. We're talking near gale-force winds on Thursday morning, with a cross-shore blow and a massive 12ft, long-period swell. The combined energy is well over 3000. It’s a full-on storm scene, with heavy rain and lightning risk. That’s not surfing, that’s a survival mission. This continues into Friday and the weekend. The swell stays big, but the wind is relentless and onshore. It’s a total washout. The energy stays high through to the end of the forecast, but the winds just absolutely kill it. The 14th and 15th are more of the same: fresh cross-onshore breeze, big messy lumps. We’re looking at a proper blank run after that Monday.
So, your options are limited. The standout is definitely the morning of Monday, September 7th. If you're an experienced surfer looking for a proper, powerful left or right, that’s your window. The other small window is Thursday the 3rd afternoon, but it’s a much smaller, more average day. For the second week, don't get your hopes up, the wind just doesn't let up. The setup looks more interesting for kite surfing than paddle surfing, to be honest. With that much swell and that much wind, the beach will be a mess.
Keep an eye on that forecast for the 7th, because that’s the one that has some real potential. But be aware that anything that far out is promising but less certain. Stay safe out there.
