The Lowdown

G’day, Rusty here. Let’s break down what’s ahead for Little Austi and Main Beach. To be honest, the next couple of weeks look pretty flat and messy. Water temp is around 64° with a slight anomaly of 0.5°, so about average for this time of year.

Right off the bat, Sunday the 6th is a total dud—1ft NE swell with a cross-onshore breeze and only 25 units of combined energy. Monday the 7th morning shapes up a bit with a light NNW cross-off wind and a 1ft SSE groundswell at 11 seconds, energy up to 53. It’s surfable but nothing to get excited about.

Monday afternoon the 7th sees a jump to 5ft from the SSE at 9 seconds with 339 units, but it’s onshore and messy. Tuesday the 8th brings the biggest swell of the whole stretch: 8ft SSE at 8 seconds Tuesday morning with 697 units, and 6ft in the afternoon. Both are cross-onshore and choppy—honestly, this looks better for kite surfing than paddling. From Wednesday the 9th through Sunday the 13th, it’s tiny, often under 2ft, with poor conditions across the board.

The one half-decent window is Monday the 14th. Monday morning has a clean 3ft NE swell with light offshore NW wind and 62 units—surfable but ordinary. Monday afternoon is a touch better: 4ft NE at 5 seconds with a light cross-off WSW breeze and 96 units. Not a standout, but it’s your best bet.

The second week is quiet. Tuesday the 15th has some knee-high SSE swell at 2-3ft with 207-232 energy, but it’s onshore or cross-onshore. Wednesday the 16th is similar. Thursday the 17th morning shows a clean 1ft SSE groundswell with light offshore N wind and 54 energy—surfable but tiny. The rest of the week through Monday the 21st is all under 2ft, mostly poor.

The pick of the whole outlook? Monday the 14th afternoon, with that 4ft NE swell and light cross-off wind. It’s not big, not powerful, but it’s the cleanest rideable wave in a very long, flat stretch. Keep your expectations low and your eyes on the forecast—things can change.

Rusty.
