The Lowdown
G’day, I’m Rusty.
Alright, let’s talk it straight — the next 16 days are mostly a snoozer for Little Austi and Main Beach. There’s nothing that really jumps out and grabs you in the first week, and the second week is even more flat. One session on Friday the 28th of August has a bit of life, but even that has its quirks.
Tuesday morning the 25th of August starts off cloudy with a cross-off wind from the north at 15 km/h, small 4ft swell out of the NE at a short 6 seconds — you can surf it, but it’s nothing special. Energy is weak (120). By afternoon, it nudges up to 5ft out of the NE, still short period at 7 seconds, energy climbs a bit (209), but still not worth a special trip.
Wednesday the 26th is a total washout — rain, cross-on wind, just poor. Thursday the 27th offers a morning glass-off when the ESE wind drops to only 5 km/h, but the swell is tiny at 2ft NE, 8 second period, weak energy (64). It’s clean but barely rideable.
Friday morning the 28th of August is the one to target. A solid 5ft groundswell from the SSE with a long 11-second period and combined energy of 587 (moderate). Wind is light SW at 10 km/h — clean cross conditions. This is your best window by far, so grab a longboard or a fish and get out early. The downside? By afternoon the wind kicks up to 25 km/h out of the SSE, cross-on and choppy, ruining it.
Saturday 29th through to Monday 1st of September goes flat to tiny — nothing doing. Tuesday 2nd onward drops even further, with waves barely reaching 1ft to 2ft, energy in the teens. Thursday morning the 3rd of September sees a little offshore NW wind with a 2ft NE 10 second swell (energy 152), but it’s more a paddle than a proper surf.
The second week keeps the same tune: tiny waves, bad wind. Sunday morning the 7th of September offers another glassy moment with 3ft SSE groundswell at 9 seconds (155 energy) — clean but weak. For beginners, the Friday morning 5ft might be a little much, and otherwise nothing tops 3ft.
Water temperature is 64°F, dead on average for the season.
So here’s the take: if you’ve got one morning free, make it Friday the 28th of August. The rest of the 16 days is a quiet stretch — this spot can go blank like this sometimes, and forecasts might shift, but right now it’s a long wait.
Rusty.
