The Lowdown
Alright, let’s talk about Little Austi and Main Beach in numbers you can feel. The next couple of weeks are pretty lean – we’re mostly looking at small, clean windows between long runs of junk. First chance is Wednesday morning September 2: a tiny 1ft swell from the ENE with a nice 10‑second period and a light offshore NW breeze at9 mph. Combined energy is only54 (weak). It’s clean but tiny – bring a longboard.
Then we hit a dead spell. From Wednesday afternoon all the way through to Monday morning September 7, it’s all poor: onshores, cross‑shores, and almost no energy. That’s five days of nothing worth paddling for.
Tuesday morning September 8 brings a bit more: 4ft from the NE (7‑second period) with combined energy at142 (moderate). Wind is light cross‑off from the NNE, so it’s clean enough, but the short period means the waves will be soft. The afternoon jumps to 6ft but gets onshore and messy – more of a kite‑surfing scene than a paddle.
Another dry stretch from Wednesday September 9 through Saturday September 12: onshores, rain, and tiny waves.
Then Sunday morning September 13 – 2ft from the E (9‑second period) with a light offshore NW wind at9 mph. Combined energy97 (moderate). It’s clean and has a bit of shape. The afternoon is similar. But the real gem is Monday morning September 14: only 2ft from the E (8‑second period), but it’s glassy – wind is NNW at just3 mph, dead calm. Combined energy68 (weak). When it’s that clean and crowds are only “sometimes” (maybe a few locals out), you can have a blast on a log or a funboard. That Monday morning is your best bet for the whole 16‑day run.
After that, it fades again. Tuesday and Wednesday have onshore winds and tiny swell, and the last few days are mostly poor. So if you’re going to go, target that glassy Monday the 14th, or the offshore Sunday the 13th. The rest? Stay home.
