The Lowdown
Alright, folks, Rusty here again. Let’s talk about Little Austi and Main Beach in feet and miles per hour, because that’s how we do it. The next 16 days are looking flat and mostly junk. There’s a big gap with nothing worth paddling out for.
We start on Tuesday, September 1st. Clear skies, a light NNW breeze blowing cross-off, but the swell is tiny – just 1ft from the ENE, period 9 seconds. The combined energy is weak (27). Water temp is 64°, about average. Tuesday afternoon is a bit better with a 1ft swell and an 11-second period, but still ordinary.
Wednesday the 2nd has a morning offshore NW wind at 9 mph, but the swell is only 1ft, period 10 seconds. Clean, but tiny. Afternoon goes cross-off from the WSW.
Thursday the 3rd through Saturday the 5th are all poor. Saturday morning has a 3ft NE swell, period 5 seconds, with offshore winds, but it’s just poor quality. The energy is weak (46).
Sunday the 6th and Monday the 7th are flat. Monday afternoon sees a jump to 5ft from the NE, period 6 seconds, energy at 203 (moderate), but it’s cloudy with light cross-shore winds and marginal conditions. That’s the closest we get to a pulse.
From Tuesday the 8th through Monday the 14th, it’s all poor surf. Tiny swells, onshore winds, or no energy. There’s a glassy moment on Saturday the 12th afternoon with a 1ft SE swell, period 9 seconds, but it’s weak (31).
The only real standout is Tuesday morning, September 15th. A 4ft swell from the NE, period 6 seconds, energy at 241 (moderate). But the wind is cross-on from the SSW at 12 mph, making it choppy and poor.
Then on Wednesday morning, September 16th, we get a clean 3ft from the NE, period 6 seconds, with offshore WNW winds at 6 mph. The energy is weak (58), and it’s just “surfable but very ordinary.”
So, nothing to get excited about. The best bet is a small, clean wave on Wednesday morning the 16th if you’re itching. Otherwise, it’s a long, flat spell. For kite surfers, some of those windy afternoons might offer a bit of chop, but for paddle surfing, it’s a quiet one.
Stay patient, mates.
Rusty.

A general guide to surfing at Little Austi and Main Beach can be found by selecting the local surf guide option on the grey menu.
