The Lowdown

G’day, I’m Rusty. Let’s have a look at what’s on offer.

Honestly, mate, it’s a bit of a flat spell for Little Austi and Main Beach. The whole 16-day window is a struggle, with only a handful of mornings that are even surfable, and even then, it’s pretty ordinary. The first few days are tiny, with a slim chance of a ridable wave from Thursday morning, August 6th. That morning you’ve got a clean 0.7ft SSE swell with a period of 12 seconds, but the combined energy is weak (21). The water temp is 64°, which is about average for this time of year.

Friday morning, August 7th, is a little better, with a 1ft SSE swell, period 10 seconds, and clean conditions thanks to a light W wind. The energy is still low (51). Saturday morning, August 8th, is probably the best of the first week. It’s glassy, with a 1ft SSE swell, period 9 seconds, and energy at 50. It’s surfable, but you won’t be writing home about it.

Sunday morning, August 9th, sees a slight bump to 3ft from the ENE, period 9 seconds, and the energy ticks up to 130 (moderate). The wind is cross-off from the N, keeping it clean. Monday morning, August 10th, brings the biggest swell of the period at 6ft from the ENE, period 9 seconds, and the energy jumps to 464 (strong). But the wind is a strong 40 km/h cross-off from the W, so it’s going to be messy and blown out.

After that, it drops back to tiny stuff. From Tuesday, August 11th, right through to the end of the period on Friday, August 21st, the swell is mostly 1.0ft to 2ft, with the energy staying below 100. The winds are often onshore or cross-onshore, making it choppy and uninviting. There’s a brief glimmer on Thursday morning, August 20th, with a clean 1ft SSE swell, period 13 seconds, and energy at 98, but it’s still very small.

The only real standout – and I use the term loosely – is that Saturday morning, August 8th. It’s the cleanest, glassiest window with the most fun-sized, rideable waves, even if they’re tiny. The crowds are listed as “sometimes,” so you might have a few others out, but it’s the best of a poor lot.

If you’re a beginner, the biggest swell on Monday the 10th is over 5ft, so that’s probably too much. For the rest, it’s all small and weak. The setup is a beach and reef, so with the bigger swell and strong wind on the 10th, it might be more interesting for the kite surfers than paddle surfers.

So, get out on the 8th if you can, or just wait. The forecasts can change, but for now, it’s a long, quiet stretch.
