The Lowdown

G'day, I'm Rusty. Look, I've had a good look at the charts for Little Austi and Main Beach, and I've got to be straight with you – it's going to be a pretty quiet run. We're looking at a long stretch of small, weak surf from now, well into the end of August. The water temp's sitting at 63°F which is about average for this time of year, so no surprises there.

Starting from Thursday the 13th through to about Saturday the 15th, we're looking at tiny waves around 1.0ft to 2ft, mostly from the ENE with a short period around 9 to 10 seconds. The wave energy is weak, sitting between 20 and 55 (units), and the wind is light and cross-shore, but it's not enough to make anything worth paddling out for. It's all poor.

Come Sunday the 16th, we see a bump in swell height to 5ft from the SE, but the period is a pathetic 6 seconds, so it's all windswell junk. The combined energy jumps to 221 (units), but the wind's onshore from the SE at 12 mph, so it's messy and poor. Monday the 17th drops back to 4ft, still weak period, and the wind is either onshore or cross-onshore, keeping it choppy.

Now, there's a little window on Wednesday the 19th in the afternoon and into Thursday the 20th morning that gets a tiny bit interesting. Waves are 4ft dropping to 3ft from the ESE, still short period around 6-7 seconds. But here's the thing – on Wednesday afternoon we get a glassy wind from the east at just 3 mph, and on Thursday morning the wind swings to a light offshore from the NNW at 6 mph. That would clean things up, but the swell is still weak. These are described as "surfable waves but very ordinary conditions", so it's a small wave cruiser, not a standout. The combined energy on Wednesday afternoon is moderate at 135 (units), and Thursday morning just below at 99.

From the 21st to the 22nd, the surf drops further to 2-3ft, with some offshore winds from the NNW at 9 mph, keeping it clean. Not a lot of push.

Then we get into a longer run of poor conditions from the 23rd through to the 27th of August. The swell stays under 3ft, the period is short, and the wind is mostly cross-offshore or cross-onshore, with moderate to fresh breezes. On the 23rd and 24th, we even get some 16 mph winds, so it's not inviting.

The 27th and 28th are flat – almost no swell, and strong winds ramping up to 25 mph from the south. That's a complete write-off for surfing, and honestly, that kind of setup with a beach and reef break, strong winds, and small junk swell might be more interesting for kite surfing than paddling.

Overall, the best we've got in this entire 16-day window is the afternoon of Wednesday the 19th and the morning of Thursday the 20th. Even then, it's marginal. No real standouts here, folks. It's just one of those quiet spells for the area. Forecasts can change, so keep an eye out.

Rusty.
