The Lowdown

Alright, Rusty here. Let's have a squiz at what's on the table for Little Austi and Main Beach over the next couple of weeks. I ain't gonna lie to ya, it's a pretty flat and quiet stretch we're looking at.

To kick things off, the water temp is sitting about average for this time of year. Overall, we're looking at a long, drawn-out run of small, weak surf with barely enough punch to get you excited. The combined swell energy is mostly in the doldrums, with values like 27, 69, and 58 in the first few days – that's weak, barely a bump. There are some bigger numbers later, but the quality just isn't there.

The first real chance to get wet comes on Tuesday the 1st of September with a tiny 1.0ft to 1ft ENE swell. It's clean with a cross-off breeze, but let's be honest, it's knee-high at best. The period is 9-11 seconds, offering decent shape for the size, but you'll be fighting for a ripple.

Wednesday the 2nd is similar, with a 1ft wave and an offshore WNW wind blowing at 12 mph in the morning, which will keep it clean. But the swell energy is still very low (58).

We've got a bit more push on Monday the 7th, where the swell bumps up to 4ft in the morning and 5ft in the afternoon from the NE. The combined energy jumps to 98 and then 163 (moderate energy), with a short period of 6-7 seconds. The wind goes offshore in the afternoon, making it clean. This is the only real window where the size gets interesting for a shortboard, but the short period means it'll be a bit lumpy and disorganised.

After that, we slide right back into tiny stuff. The longest gap with no real recommendation runs from the 8th of September right through to the 13th. There are a few days with a 3ft to 3ft swell from the NE, but the winds are all over the place – cross-on, south-easterlies, or just messy. The combined energy is still only in the 100-167 range, which is weak to moderate at best. It's not worth the paddle.

The last date worth a mention is the 16th of September, a Wednesday. We get a 3ft swell from the SSE with a clean offshore NW wind at 6 mph. The energy is still weak (79), but conditions will look clean. It's a last-chance saloon kind of session.

In summary, this break is a beach and reef setup, and it's exposed to the ENE, which is the optimum direction. The problem is the swell just isn't big enough or consistent enough. There's nothing here that's a standout. The best of a bad bunch is Monday the 7th in the afternoon for the size, and maybe the 16th for the cleanness, but even then, don't expect much. For beginners, the biggest swell is 5ft, which is fine, but the short period will make it tricky. For experts, there's nothing here to get excited about. The whole forecast is a bit of a struggle. Keep your eye on the charts – it tends not to stay this poor for long.

Rusty.
