The Lowdown

G'day, Rusty here, and I've gotta be straight with you – the next couple of weeks are looking pretty grim for a paddle. We’ve got a long, dry spell ahead. The first real chance of anything decent isn't until Monday the 10th of August, so we're looking at nearly a week of flat to tiny, poor-quality surf before things even get interesting. It’s a tough stretch.

The only spot on the radar for the whole forecast is Little Austi and Main Beach. It’s a beach and reef setup, fairly consistent, but it’s not going to be doing much for a while. The water temp is sitting at a pretty standard 65° for this time of year, so nothing unusual there.

From now until the end of the first week, it’s a write-off. Swell is tiny, mostly under 2ft, with short periods and weak energy. The wind is mostly cross-off or cross, which is alright, but with barely any swell to work with, it’s just not worth getting wet. The energy readings are all in the double digits, with the highest being just 85 (weak energy), so there’s just no power in the water.

Then, we finally get a pulse on Monday the 10th of August. The morning session is the standout of the whole forecast. We’re looking at a solid 6ft groundswell from the ENE, with a period of 9 seconds. That’s a decent energy jump – the combined energy reading hits 419 (strong wave energy). The wind is offshore from the WNW at 12 mph, which is going to keep things clean and lined up. This is the best we’ve got, and it’s not even a huge day. Because it’s a beach and reef, that longer period swell might make it a little straight, but with offshore wind, it should still be fun. It’s a bit too big for beginners, but a good one for the experienced crew.

The afternoon of the 10th drops off a bit to 4ft, and the wind swings cross-off, so it’s still surfable but not as good as the morning. After that, it’s back to the doldrums for the rest of the second week. From Tuesday the 11th onwards, we’re back to tiny, weak swells under 3ft, with energy readings dropping back to double digits and low triple digits. There’s a couple of glassy mornings on the 14th, 15th, and 16th of August, but the swell is only 1ft, so it’s more of a longboard or a swim than a surf. The crowds at Little Austi can be a problem sometimes, so if you’re heading out on that Monday morning, get there early.

Honestly, that Monday the 10th morning is the only real window. The rest is a waiting game. Forecasts can change, but for now, it’s looking like a blank run is pretty normal for this area.

Rusty.
