The Lowdown
Alright, let’s talk about Little Austi and Main Beach. I’ll be honest with you, mate – it’s looking pretty grim for the next 16 days. This is a beach and reef spot that’s exposed to the swell, and it likes it best from the east-northeast. Water temp is about 64°F, which is right where it should be for this time of year.
The first record we’ve got is Saturday, August 29th, in the afternoon. There’s a 4ft SE swell with a 9-second period, and the combined energy is 226 – that’s moderate. But the wind is onshore from the ESE at 6 mph, and the conditions are tagged as poor. Not a good start.
From there, it’s a long, dry spell. Almost every session from Saturday afternoon through to the end of the forecast is either poor or very ordinary. There’s a tiny glimmer on Sunday morning, August 30th – a 2ft SE swell, glassy, with calm wind. That’s the kind of morning you might take a longboard out for a paddle, but the energy is weak (73 combined energy), so it’s surfable but nothing special. After that, we’re looking at days of tiny, weak, or flat conditions. Some mornings have offshore wind – like Tuesday, September 1st, with a 1ft ENE swell and a NNW wind at 6 mph – but the swell is just too small to ride.
The energy drops off a cliff. From September 4th onward, we see combined energy in the teens, single digits, and even zeros. There’s a little blip on September 5th with a 3ft NE swell, but the period is a short 6 seconds and the wind is a fresh 19 mph WNW cross-off. That’s more of a windy, messy day than surf. For a beach and reef setup, that looks more like kite surfing conditions than paddle surfing.
Into the second week, it’s more of the same: tiny waves, poor conditions, and long flat spells. September 12th and 13th show a little 2ft NE swell, but short period and onshore or cross-shore wind keep it ugly. There’s no standout day in this whole 16-day window. The only session that even hints at being okay is that Sunday morning, August 30th, but it’s not going to get you excited.
Bottom line: there are no good surf options in this 16-day window. The breaks here are usually fairly consistent, so this dry run is a bit of an anomaly. Forecasts can change, so keep your eyes peeled, but for now, I’d leave the board in the car.
