The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Little Austi and Main Beach over the next couple of weeks. Gotta be honest with you, this stretch is gonna take some patience.
The first real chance to get wet doesn’t show up until Monday the 7th of September, and even then it’s not much to write home about. We’ve got a small 1ft swell from the SSE, with a long 11-second period, crossed by a light N wind. It’s clean, but the energy is weak (53). It’s surfable, but you’ll be scratching for scraps. The water is sitting at 64°, which is about average for the time of year, so no surprises there.
The next few days are honestly a write-off. Tuesday the 8th brings a messy 7ft from the SSE, but with a short 8-second period and onshore wind, it’s just a lumpy, borderline mess. Wednesday the 9th is a total no-go with 25 mph winds from the South. Thursday and Friday look equally grim, with onshore winds and tiny, gutless swell. We’re looking at a solid gap of poor conditions right through until the end of the first week.
Now, there’s a glimmer on the horizon. If you’re a patient surfer, mark your calendar for Friday the 18th of September. The morning shows a moderate 4ft from the SSE, with a 10-second period and a clean offshore wind from the NNW. The energy is moderate (316), and the wave comment says “expect good surf conditions.” This is the real standout of the whole outlook. The afternoon holds up similar with 4ft and still offshore, albeit a bit stronger wind. It’s not huge, but it’ll be clean and lined up.
The weekend after that, the 19th and 20th, drops back off into the doldrums. Small, weak swells and onshore winds take over. The 16-day window finishes up with very little to get excited about.
So, to sum it up: don’t hold your breath for the first week or so. The one true date to aim for is Friday the 18th of September. That’s your best shot at some clean, fun waves. It’s a long way out, so keep an eye on it, but the signals are there.
Rusty, signing off.
