The Lowdown
Alright lads, Rusty here. Let’s cut to the chase. Little Austi and Main Beach is looking bleak for the next couple of weeks. There’s a massive dry spell in the middle where the ocean just goes to sleep, so temper your expectations.
The first few days are a bust. Wednesday and Thursday (26th and 27th August) are a total mess with small, choppy cross-onshore wind and weak, short-period swell. The combined energy is a feeble 125 and 64, not worth getting wet for. Water temp is 64°F, which is about average for the time of year.
We get a little pulse on Friday morning, 28th August. A 5ft SSE swell with an 11-second period, combined energy of 606 (moderate). The wind is cross-shore but light, so it’s the most size you’ll see. It’s a bit much for beginners, but it’s the only window with any real push. The morning is the best bet, but it’s still only marginal.
Saturday morning, 29th August, has a similar look with 6ft SSE swell and 747 energy, but the wind is cross-onshore (SSE at 6 mph), so it’ll be bumpy. That’s getting too big for beginners, and the quality won’t be there.
From Sunday 30th August onward, it’s a long, slow fade. The swell drops below 3ft, and the energy readings are in the teens and twenties. There’s a glassy moment on Sunday morning, 30th August, with 2ft SE swell and 107 energy, but it’s tiny. Clean for a longboard if you’re keen, but not worth a trip.
Then we hit a massive gap. From Monday 31st August all the way through to Tuesday 8th September, the swell is consistently under 2ft, often down to 0.7ft, with energy readings as low as 3. That’s flat. The wind is mostly offshore or cross-offshore, so it’s clean, but there’s simply no water moving. Don’t bother.
The only faint glimmer in the second week is Tuesday morning, 8th September. A 2ft SSE swell with a very long period of 14 seconds rolls in, giving 175 energy. The wind is glassy (WNW at 3 mph). That’s a classic long-period groundswell, but at a beach and reef setup like this, it might be too straight for good shape. Still, it’s the cleanest wave in the whole 16-day window. But it’s tiny.
The rest of the second week is flat as a pancake, with energy readings of 7, 8, and 21. Nothing to see.
So, the standout? The Friday morning, 28th August, with 5ft SSE swell and 11-second period is the most size on offer, and the light cross-shore wind makes it just about surfable for the experienced crew. The later Tuesday morning, 8th September, is the cleanest, glassiest option, but it’s small and long-period. That’s about it.
Rusty out.

Further information to help with frequently asked questions about our surf forecast for Little Austi and Main Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
