The Lowdown
Alright, folks, Rusty here. Let's get into it.
Well, I've gotta be straight with you. The next couple of weeks are looking pretty bleak around here. We've got a long stretch of tiny, weak surf and uncooperative winds ahead. The first real chance of a session doesn't come around until Friday the 11th of September, and even that's marginal. There's one standout that looks worth circling on the calendar, though.
Let's start with this first opportunity. On Friday the 11th of September, Little Austi and Main Beach might just give us something in the morning. We're looking at a 4ft swell from the SSE with a 12-second period. That's some long-period groundswell energy moving in, with a combined energy of 445 (moderate), so there's some push behind it. The catch is the wind is a light cross-onshore from the SSE, leaving a few bumps on the surface. The tide might also be a factor – it's called "marginal" conditions. Not perfect, but for this break, it's the first pulse in a long time.
Now, the real standout. Circle Saturday the 12th of September. The morning looks promising at Little Austi and Main Beach. We're seeing a bump in swell to 7ft from the SSE. That's on the bigger side, so it's probably a touch too much for the beginners. The combined energy jumps up to 822 (moderate to strong), which tells you there's some serious grunt in the water. The wind is set to be light and offshore from the north, which is key – that means clean, glassy faces. The forecast is calling for "very good surf conditions." This is our best bet across the entire forecast, but keep in mind it's over a week away, so there's less certainty. The size and the clean wind make this the one to aim for.
For the rest of the run, it's a write-off. Late August through the first week of September is a total bust. Tiny waves under 3ft, weak energy, and mostly clean but gutless conditions. The water temp is sitting around 64° with a +0.9° anomaly, which is pretty average for this time of year after a decent summer.
So, my advice? Save your energy for the morning of Saturday the 12th of September. That's where the goods are.
Rusty.
