The Lowdown
G’day, I’m Rusty, and here’s the scoop on Little Austi and Main Beach. It’s lookin’ pretty flat and funky for a while, so don’t get your hopes up too high.
The first chance to get wet is Saturday morning, 29 August. Some clouds overhead, a 4-foot swell out of the SSE at 10 seconds, with a cross-onshore breeze from the SSE at 3 mph. The combined energy is moderate at 276, so there’s some life, but the wind is messin’ it up a bit. Water temp is 64°, right about average. Not a stunner, but it’s something.
Sunday morning, 30 August, is the real gem—dead calm, glassy as a mirror. The swell is a tiny 2 feet from the SE, 10-second period, and the energy is down to 126. Small but clean as can be. This is your best shot for a smooth, fun session in the whole 16 days. No word on crowds, so maybe you’ll have it to yourself.
Then comes the drought. From Monday onward, it’s a wasteland of tiny, weak swells under 2 feet and poor conditions. There’s a 7-day stretch where nothing’s worth mentioning. Even when the wind goes offshore, the waves are just too small.
Monday, 7 September, energy jumps to 211 and 233 with swells around 5 feet from the NE and SSE. But the wind is screaming at 25 mph out of the WNW. It’s clean on the offshore side, but that’s a kite-surfing gale, not a paddle-surfing day.
Wednesday, 9 September afternoon throws a 7-foot sSWell from the SSE at 9 seconds, with energy at 687. Wind is light onshore from the SE at 6 mph. That’s a big, powerful wave—too big for beginners—and the onshore breeze will make it lumpy.
Thursday morning, 10 September, cleans up with a light offshore from the NNW at 6 mph. Swell is 3 feet from the SE, 8-second period, energy at 119. Small but clean—another decent window.
Finally, Sunday morning, 13 September, has a light offshore from the NNW at 6 mph, with a 3-foot swell from the SSE, 10-second period, and energy at 178. Glassy and clean again.
Top picks: Sunday, 30 August for that dead-calm glass; Thursday, 10 September or Sunday, 13 September for clean offshore conditions. The rest is a bust. Keep your board waxed and watch the charts—it usually turns around.
Rusty.
