The Lowdown
G’day, Rusty here.
Alright, I’m not gonna sugarcoat it—this 16-day stretch for Little Austi and Main Beach is pretty bleak. The swell is tiny for the whole run, and most days aren’t even worth looking at. Let’s break it down.
Overall Pattern
The forecast starts with a small opportunity this morning, Monday the 7th of September, but then we hit a long, flat patch that lasts over a week. The waves are small and wind is a problem for most of the period. It’s not until the middle of the second week that we get a couple of clean windows, but even those are weak.
Monday 7th September – The Only Near-Term Shot
This morning is your best bet for a paddle. We’ve got a clean 1ft SSE swell with a long 11-second period giving it a bit of shape, and a light cross-offshore breeze from the NNW at 6 mph. The combined swell energy is low at only (53), so it’s not powerful, but the conditions are glassy and clean. It’s a small wave day for sure, but if you’re after a quiet session, this is it.
By Monday afternoon, the wind swings onshore from the SSE at 12 mph, and the swell jumps to a messy 5ft with a short 9-second period. The energy bumps up to (339), but it’s cross-onshore and choppy. Not worth your time.
Tuesday 8th September to Sunday 20th September – The Big Flat Spot
From Tuesday morning right through to the weekend, it’s mostly close to flat. Swell heights are often 0.7ft to 1ft, and when there is a bit of size—like Tuesday afternoon’s 7ft SSE swell—the period is a weak 9 seconds and it’s cross-onshore. That’s the kind of mess that’s more interesting for a kite than a paddle. Winds are generally cross-onshore or onshore, with only a few clean morning moments on the 13th, 14th, and 16th of September, but those come with barely any swell.
There’s a brief uplift on the 14th of September (Monday afternoon) when we get a clean, glassy 4ft NE swell with light offshore wind from the NW at 3 mph. The energy is moderate at (112), and the waves are surfable. It’s the best of a bad bunch, but still only a so-so session.
Mid-to-Late Second Week (18th – 20th September)
Friday the 18th of September afternoon shows a bit of hope, with a clean 3ft S swell, glassy conditions (calm wind), and a short 5-second period. Combined energy is only (66), so it’s weak but clean. Again, it’s small and not punchy.
Saturday the 19th and Sunday the 20th of September have clean cross-offshore winds, but the swell drops to 1ft or less. Not enough to get excited about.
Summary
Truth is, there’s no standout session in this forecast. The best on offer is Monday 7th September (this morning), with clean, tiny waves and a nice offshore breeze. After that, Monday 14th September afternoon is the next best call if you’re desperate—clean and glassy with a bit more push. But both are very average. It’s mostly flat and messy, with a long gap between any reasonable swell. If you need to get wet, stick to the first Monday morning, or you’ll be waiting nearly a week and a half for the next clean window.
