The Lowdown
Alright, Rusty here. Let’s break down what’s cookin’ for Little Austi and Main Beach.
Honestly, it’s a pretty lean run for the next couple weeks. For a break that’s usually fairly consistent, we’re looking at a long dry spell at the start. Nothing worth paddling out for from now until the morning of Wednesday, August 19th. The water’s sittin’ at 63°, which is right on average for this time of year, so no weirdness there.
Wednesday, August 19th morning is your best bet. We got a small 4ft swell comin’ from the ESE with a short 7-second period. The combined energy is moderate at 216, but the real winner here is the wind – dead calm, glassy. That’s huge. The wave report says “expect good surf conditions.” It ain’t big, and it’s short-period, but for a beach and reef break with clean glass, this is the only real window to get a few fun ones.
After that, it drops off fast. Thursday morning the 20th has a clean 4ft easterly swell with light cross-offshore wind, but it’s just ordinary. Friday the 21st brings a light offshore from the NW with 4ft from the east, and by the afternoon it goes glassy again with 4ft – surfable, but nothin’ special.
Then it goes quiet again until Sunday the 23rd afternoon when a big 10ft SSE swell rolls in with a 10-second period. The energy is massive at 1361, but the wind is onshore from the SSE and it’s labelled marginal. With size over 8ft, this is for experts only, and with that wind, it’ll be choppy. More of a kite day than a paddle day at this beach and reef setup.
The last spike is Friday, August 28th morning with an 12ft SSE swell and 2472 energy – huge numbers again, but cross-onshore wind and poor surf conditions. Same story: big, windy, and messy.
So, your one true standout is that glassy Wednesday the 19th morning. It’s small, but it’s clean. The rest of the 16 days are either flat, blown out, or way too big and rough. I’d pencil in that Wednesday for a dawny.
Rusty.
