The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Little Austi and Main Beach.
Honestly, the next week and a half is a bit of a struggle. There’s a lot of small, weak, and messy conditions in the mix. The first real opportunity we get is on Saturday, September 12th. The morning is the pick of the whole outlook. We’re looking at a clean 4ft swell from the SSE with a light cross-offshore breeze. The wave energy is moderate at 441. It’s not going to be a giant session, but the conditions will be clean and the swell direction is close to that optimum ENE. It’s a fairly consistent spot, so there’s a good chance of a few fun ones. The water temp is sitting around 64°, which is about normal for this time of year.
After that, it’s back to the doldrums for a long stretch. There’s a small window on Wednesday, September 16th morning. The wind goes glassy, which is always a treat, and there’s a 4ft swell from the SSE. The energy is moderate at 180, but the conditions are described as very ordinary. It’s surfable, but it’s nothing to get excited about.
Then we have another long gap. The next time you might want to get wet is late on Friday, September 18th afternoon. It’s glassy again with a 3ft swell from the NE, but again, it’s just ordinary. The following morning, Saturday, September 19th, offers a clean 3ft from the NE with a light offshore from the NNW. It’s a small wave, but the wind is right and the surf is clean. The energy is weak at 89.
Later in the outlook, on Wednesday, September 23rd morning, we have a 4ft NE swell with a light offshore breeze from the NW. The energy is moderate at 155, and it’s clean. It’s a weekday, so crowds might be less of an issue, but it’s still a small wave affair.
So, the standout is the Saturday, September 12th morning session. After that, it’s a wait-and-see game with a few glassy but ordinary days sprinkled in. The long gaps between any decent surf are the story here. Keep an eye on the forecasts, because it can change.
Rusty.
