The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks.

Right off the bat, I gotta be straight with ya – the first week is a bit of a flat spell. Little Austi and Main Beach is mostly showing tiny, poor surf. We’re looking at a run of nothing really worth paddling out for from the 31st of August right through until the 7th of September. The few days in there are just small, weak waves with not enough energy to get excited about. The combined energy’s barely cracking 100 (17) on the 31st, so it’s proper weak.

Then, on the 7th of September, we finally see a lift. It’s still not great, but at least there’s a bit of swell. Monday afternoon the 7th has a 4ft swell from the NE, period of 6 seconds, with a moderate offshore wind from the NW. That’s surfable, but nothing to write home about. The combined energy is moderate (113), but it’s still a bit short-period and messy.

The real standout, and the one to circle on your calendar, is the 10th of September. Thursday morning is where it’s at. We’ve got a solid 13ft swell from the SE, with a period of 10 seconds. That’s a nice, powerful groundswell. The combined energy is a massive 2863, so there’s plenty of grunt. The wind is glassy, light from the ESE, so it’ll be clean as a whistle. This is expert territory, though – 13ft is no joke, and it’s a beach and reef setup, so you’ll want to be on your game. The water temp is about 64°F here, which is bang on average for this time of year.

The following morning, the 11th, the swell drops to a still-chunky 6ft from the E, with a 10-second period, but the wind turns a little cross-onshore, so it’ll be a bit bumpier. Still, with 748 combined energy, it’s got some push. The 12th of September morning looks like a decent option too, with 5ft from the E, 9-second period, and a clean cross-offshore breeze from the NNE. The energy is moderate (449). That’s a solid intermediate day.

After that, the swell fades back into the small stuff from the 13th onward, with poor conditions and onshore winds taking over. The 14th and 15th are just tiny, weak, and messy.

So, to sum it up: the first week is a write-off. The 10th of September morning is the one true standout – big, powerful, glassy, and for experts only. The 11th and 12th mornings are your next best bets for a paddle, but they won’t be as clean.

Stay frothy, and I’ll catch you on the next one.
