The Lowdown
G'day, I'm Rusty. Let's have a look at what's on the cards for Little Austi and Main Beach.
Overall, it's a pretty quiet run ahead. The surf is small for most of the next couple of weeks, and there's a big gap with hardly anything worth paddling out for. The best of it looks like it'll be Friday morning, the 28th of August, when a bit of energy pushes through.
The water temp is sitting at about 64°, which is about normal for this time of year, so nothing to worry about there.
The first real chance of anything decent comes on Friday morning, the 28th of August. We've got a 5ft swell from the SSE, with a solid 11-second period, and the combined energy is moderate at 600. The wind is a light cross-shore, so it'll be a bit bumpy, but it's the biggest and best-shaped swell we'll see. It's a bit much for beginners, but a good option for the crew who want to get wet.
Saturday the 29th of August sees the swell drop to 4ft, still from the SSE. The morning is glassy with a light breeze, so it'll be clean, but the energy is down to 286, making it pretty marginal. The afternoon goes cross-onshore and drops to 4ft, so don't get too excited.
Sunday the 30th of August starts with glassy conditions and a tiny 2ft swell from the SE, with weak energy (126). It's surfable, but nothing to write home about. The afternoon is even smaller.
From Monday the 31st of August, things get really quiet. The swell drops below 2ft and the energy is weak, with values mostly under 50. There's a long stretch of days with tiny, poor surf. The wind is often offshore or clean, but there's just no swell to work with.
There's a flicker of life on Saturday the 5th of September afternoon, with a 4ft swell from the NE, but it's a short-period 5-second wind swell, so it'll be messy. The energy is weak at 107, and it's not worth chasing.
Sunday the 6th of September morning has a 4ft swell from the NNE, but again, a short 6-second period. The wind is calm and glassy, so it'll look clean, but the energy is still weak at 147.
After that, it's back to tiny surf for the rest of the run. The 8th of September onwards has nothing but 0.7ft to 1ft waves with very weak energy, often under 20. The wind is occasionally offshore or glassy, but there's no push.
So, the standout is Friday morning, the 28th of August, with that 5ft SSE swell. It's not perfect, but it's the best wave we'll see in this window. The rest of the time, it's a waiting game.
Rusty.

A general guide to surfing at Little Austi and Main Beach can be found by selecting the local surf guide option on the grey menu.

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.
