The Lowdown
G'day, Rusty here. Looks like we're staring down a pretty flat run for a while, so don't be in a hurry to grab your board just yet. For the first week, there's barely a ripple to get excited about at Little Austi and Main Beach, but things do start to look up in the second week if you're patient enough to wait.
Right off the bat, Tuesday afternoon the 1st of September offers up tiny 1ft waves from the ENE with a light offshore breeze. It's clean, but with combined energy sitting at a measly 64, it's more of a splash than a surf. That sets the tone for a long, frustrating stretch. There's nothing worth paddling out for from Wednesday the 2nd right through until Monday the 8th of September. Mostly clean, but just no push behind it.
Now, Tuesday morning the 8th of September that's a different story. The swell jumps up to 3ft from the SSE with a moderate energy reading of 361. The wind is clean off the land, so the face should be nice. This is your first real chance, and it's the better of the two mornings that day, before a bit of light rain and a drop in energy on Tuesday afternoon.
The real standout, though, is Monday morning the 14th of September. This is the pick of the whole forecast. We've got 5ft of clean swell from the ESE, period around 11 seconds, and combined energy roaring at 431. The wind is glassy – dead calm. That's as good as it gets. With those conditions, it'll be clean, with some proper energy behind it. The water temp is a pretty average 64°F for this time of year, nothing unusual.
Just a heads-up, keep an eye on Wednesday morning the 9th of September. There's a 5ft SSE swell on the cards with a short, choppy 6-second period and moderate energy of 271. The cross-offshore wind might keep it tidy, but that short period means it could be a bit of a close-out mess. Probably more for the experienced crew that morning. After that, the surf fades right out again through the middle of the month before that Monday glass-off.
So, if you can hold out, Monday the 14th is your day. Glassy 5ft from the ESE. Everything else is a big gamble or a flat wait.
Rusty.
