The Lowdown
Alright, this is Rusty, and I'm gonna give it to you straight about Little Austi and Main Beach.
Alright folks, for the next couple of weeks we’re really up against it here at Little Austi and Main Beach. The water temp is sitting at 64° right now, which is pretty much dead average for this time of year, so nothing to write home about that. But the surf? Man, it’s a tough stretch. We’re looking at a gap that runs for more than a week with nothing worth paddling out for. From Wednesday the 2nd right through to Friday the 11th, it is a real struggle. The swells are tiny, mostly under 3 ft, and the period is short and weak – we’re talking combined energy readings under 100 for the most part, just minimal pulse after minimal pulse. The wind is cross-off or cross-on, but even when it’s clean the waves just aren't there. It’s the kind of run that will have you checking the forecast twice and putting your board back in the truck.
The first real glimmer of hope arrives on Saturday the 12th of September. The morning session is the only standout in the whole outlook. We finally get a pulse of south-southeast swell pushing in at 4 ft with an 11-second period. You can feel the difference in the numbers – that combined energy jumps right up to 391, a proper moderate pulse. The wind is a gentle northerly cross-off, and the call is for clean waves. For a spot that can be good on its day, this is the time to be out there. The swell direction is from the SSE, which is about as good as it gets for this exposed spot that likes it from the ENE.
Other than that, the afternoon on the 12th gets chopped up by a stronger north-easterly. Monday the 14th has a bit of size in the afternoon with 5 ft of SSE swell, and a decent 302 combined energy, but that north-easterly wind is blowing cross-shore and making a mess of it. That’s a session for the windsurfers and kites, not for a clean paddle. The rest of the window into the second week is small, weak, and messy. There’s nothing else out there worth chasing. It’s a long blank run, so don’t hold your breath. Forecasts can always change, but right now, this is a lean period.
Rusty.
