The Lowdown
Alright folks, Rusty here. Let's be straight with you: the next couple of weeks are looking pretty flat and grim for our stretch of coast. We've got a long stretch of nothing but small, weak, and messy conditions on the horizon. It's the kind of forecast that makes you want to hang the board up for a bit, but I've seen this place turn around before, so don't lose hope just yet.
We're looking at a real dry spell from now through the middle of next week. For days, the swell is tiny, and the winds are all over the shop, mostly cross-shore or onshore, making everything choppy and uninviting. The water temp at Little Austi and Main Beach is sitting at 64°F, which is about normal for this time of year, so at least a wetsuit will feel comfortable.
The first real glimmer of hope comes late in the period, on Sunday the 20th of September. The models are showing a pulse of longer-period southerly swell pushing in. The morning is looking best with a clean 8ft of swell from the SSE. The energy is going to be very strong (1292), and it looks like it has some punch. That's the standout morning of the whole run—clean conditions with a moderate cross-offshore breeze. It'll be big, so make no mistake, this one’s for the experienced crew only. The afternoon gets a bit messier as the wind swings and picks up.
The swell backs down a touch into Monday the 21st, still with some size but the conditions look less clean. There's a window on Thursday the 24th of September, with the swell mixing between a couple of directions. The morning has some light offshore flow and a decent 5ft wave, but the real go is Thursday afternoon: 8ft from the NE with clean conditions and a light cross-offshore breeze. That’s another solid pick, though the energy is moderate (585). It's a second-week call, so treat it as promising but not locked in.
So, there you have it. A whole lot of nothing to start, then a couple of windows for the experienced surfers. Keep the days open around the 20th and the 24th and keep your fingers crossed the forecasts hold. The confidence is low for the later stuff, but it's better than staring at a flat ocean.
Rusty out.
