The Lowdown
Alright, Rusty here. Let’s have a look what’s cookin’ for Little Austi and Main Beach over the next couple weeks, in feet and miles.
Honestly, it’s gonna be a long haul with not much to get excited about for most of the period. We’ve got a big gap of flat, poor conditions sitting right in front of us. The first real sniff of anything half-decent doesn’t show up until Tuesday the 8th of September. Before that? Nada. Just small, weak dribble with ripples and choppy wind – that’s from Friday arvo the 4th right through to Monday the 7th. A real tease on Monday morning with glassy surface but only 0.7ft, and no energy to push it. Forget it.
Now, Tuesday the 8th of September morning – that’s where we get a little spike. The swell jumps to 7ft from the SSE with a period of 11 seconds (1071 energy). That's moderate to strong energy. But here’s the kicker: the wind is cross-onshore from the SSE, light, but not clean. The rating only calls it marginal. It’s a bit of a messy beast – not beginner-friendly at that size (over 5ft) and a bit lumpy. The water temp is 64°F, which is bang-on average for this time of year, no surprises there.
Wednesday the 9th of September morning shapes up nicer. Swell drops to a clean 5ft from the SSE (9 seconds, moderate energy at 326) with light offshore cross-off wind from the W. Conditions are clean. That is about the best on offer in the first week – a solid, clean, intermediate-sized wave. But arvo it turns to rubbish with a fresh onshore.
Then we hit another flat spell through to Monday the 14th. There’s an interesting window on Monday the 14th September – both morning and afternoon show 6ft from the SSE with period 7–8 seconds, energy climbing to 418–470. That’s moderate energy. Wind is cross-off from the N-NNE, gentle, keeping it clean. That’s a standout. Solid chest-to-head-high surf and clean conditions. For intermediates, this is the pick of the whole run. The swell direction is from the SSE, matching the optimum ENE direction? No, it’s off, but the size and clean wind still make it workable for the beach-and-reef setup here. Crowds are “sometimes” at this break, so you might get a few mates out, but nothing like a circus.
The rest of the second week is a whole lotta nothing. From the 15th, it’s choppy, lumpy, cross-onshore slop. Energy values drop, swell gets smaller. By the 19th of September – Saturday morning – there’s tiny 2ft from the SSE with long period 11 seconds (128 energy) and clean cross-off wind, but it’s barely a wave. Ordinary at best.
One true standout: Monday the 14th of September is the go, morning or arvo. 6ft clean, cross-off wind, decent energy. After that? Close the lid and wait for the next system.
Rusty.
