The Lowdown

Right, folks, Rusty here. Let's have a look at what the next few weeks are shaping up like for Little Austi and Main Beach (Little-Austi-and-Main-Beach). Gotta be straight with you, it's a tough outlook. We're looking at a long, dry spell with barely a ripple worth paddling for.

The water temp is sitting around 64°F at the start, which is pretty much what you'd expect for this time of year, so that's one thing that's not weird.

The first real chance, and I mean *chance*, doesn't pop up until Tuesday the 8th of September in the afternoon. Even then, it's a marginal call. We'll see a 8ft swell coming from the SSE, but with a short 10-second period. The wind is light from the east, but it's cross-onshore, so it'll be a bit bumpy. The combined energy is moderate at 909. Honestly, it's a tough one to get excited about.

Then things go quiet again. A whole lot of nothing until the morning of Saturday the 12th of September. That morning brings a bit of a tease: glassy conditions with an easterly wind of 3 mph, and a 1ft SSE swell. The period is a very long 18 seconds, which gives it a combined energy of 128 (moderate). That long period at a beach and reef setup? It could be a bit too straight for a quality wave, but if you're patient, there might be a clean little runner.

The next one to watch, and this is the standout of the whole period, is Monday the 14th of September. The morning is looking proper. We've got a clean 4ft swell from the SSE, with a 12-second period pushing a combined energy of 448 (moderate). The wind is offshore from the NNW at 9 mph, so it’ll be clean and lined up. For an intermediate, that's a solid session. That afternoon stays clean with a 4ft swell, but the wind swings WSW and picks up a bit.

After that, it's back to the doldrums. The rest of the run into the third week is just tiny, weak swells and mostly onshore or cross-off winds that won't do much. There's a morning on Saturday the 19th of September with a clean 1.0ft SSE swell off a 14-second period, but it's just too small to get excited about.

So, to be honest, if you're after a surf, keep your eyes on the morning of Monday the 14th of September. That's the one bright spot. The rest of the 16-day window is a write-off for most of us. The swell is just too small and inconsistent for anything more than a float.

Rusty.
