The Lowdown
Alright, Rusty here again. Let’s talk about what’s up in feet and miles per hour.
Right off the bat, this is a rough patch. For Little Austi and Main Beach (beach and reef), the 16-day window is mostly flat and blown out. There’s a long gap of basically nothing until the second week, so don’t rush to wax up.
The first few days are a total bust. Friday the 4th has tiny waves around 1ft from the NE, with combined energy at just 39 to 55. Winds are cross-off, but the waves are too small and weak to care about. Saturday the 5th arvo sees a 3ft NE pulse, but it’s a short-period, messy 6-second wind swell with a stiff NW breeze. Water temp is about average for the season.
From Sunday 6th through Thursday 12th, it’s all tiny, poor surf. Swells barely hit 3ft, most with cross-onshore wind. There’s a moment on Tuesday morning the 8th with a 7ft SSE swell and 643 combined energy, but the wind is cross-onshore and the period is only 8 seconds. That’s overhead but messy – looks more like a kite session than a clean paddle.
The only real standout is Sunday morning, the 13th. We get a 3ft SSE groundswell with a 10-second period, combined energy of 203, and clean conditions with a light NNE cross-off breeze. It’s the best we get. The swell direction is a little off the ideal ENE for this spot, but the waves will have some shape and the wind keeps it clean. Crowds are possible on a Sunday, so get out early. Water’s about average temp.
After that, it fades. Monday 14th arvo has a 3ft NE swell with offshore NW wind, but the energy is only 120 and the period is short. From Tuesday 15th onward, it’s tiny, wind-affected slop with strong onshore winds and low energy. Not worth the drive.
The standout window is Sunday morning, 13th September. It’s not a classic, but it’s clean, has some groundswell punch, and the offshore breeze will tidy things up. Everything else is a drought. Hang in there.
Rusty signing off.
