The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Little Austi and Main Beach.
It’s a tough start. We’re looking at a pretty grim run to kick things off. There’s really nothing worth paddling out for until the second week. The wind is mostly onshore or cross-on, and the swell is either tiny or just messy. You’ll be waiting a while for something decent.
The first real glimmer comes up on Saturday the 19th of September. We get a bump in size, around 5ft to 6ft from the SSE with a period of 11 seconds. That’s a nice groundswell, so the energy is there (combined energy of 556-814). The wind is light cross-on though, so it’s going to be a bit bumpy and the tide might mess with it. It’s surfable but you gotta read the banks. Not a standout, but it’s the first real pulse in ages.
The real standout window, and the best bet of the whole forecast, is Sunday the 20th of September and Tuesday the 22nd of September. On Sunday morning, we’ve got a clean 4ft SSE swell at 11 seconds with light offshore NE winds. That’s a good combo. The water temp is 64°, which is about average for this time of year. The energy is solid (384) and conditions should be clean. It’s not going to be huge, but it’ll be fun and lined up on the reef sections. Crowds are possible at Little Austi and Main Beach, so get in early.
Then Tuesday the 22nd of September afternoon is where it gets proper interesting. The swell picks up to 6ft from the SE, still around an 8-second period, with a clean offshore NW wind. The energy jumps right up (655) and the forecast is very good. That’s the session to circle. It might be a bit much for beginners over 5ft, but for the experienced crew, that’s the one.
Later in the period, Monday the 21st of September has some small, clean, glassy waves in the afternoon. Very small at 2ft, but if you’ve got a log, it’ll be a nice cruise. Not for the shortboarders.
All in all, hold out for the second week. The 20th and the 22nd are your standout days. The rest is mostly a scratch.
Rusty.
