The Lowdown

G’day, it’s Rusty here. Let’s get straight into it. The next couple of weeks are a real mixed bag, and to be honest, the first week or so is pretty slim pickings. We’ve got a long stretch of small, mostly messy waves. The water is sitting at 63°F where we’re looking at first, which is a touch warmer than normal for this time of year, so that’s a little bonus.

We start off this Tuesday morning at Moruya Rivermouth with a tiny 1ft south swell, period around 10 seconds. It’s glassy, but the energy is weak, only 62. It’s surfable but very ordinary. The afternoon turns into a gentle cross-onshore and it’s pretty poor.

Wednesday brings a bit more size, up to 3ft on the morning, but the period drops to 6 seconds, which is just messy short-period windslop. The energy picks up to 153, but the cross-shore breeze chops it up. The afternoon gets worse, with a 5ft bump and a moderate cross-onshore making it a write-off.

Thursday is more of the same, small and crossed-up, though the afternoon goes cross-off and cleans up a touch, but we’re still looking at a weak 3ft with only 99 energy. Friday and Saturday are tiny, with glassy mornings but nothing doing, waves around 2ft to 2ft. Sunday and the following Monday stay small, with a little south pulse on Monday afternoon but it’s still tiny.

Then we hit a real quiet spell. From the 25th through to the 30th, it’s a lot of small, sub-3ft surf, a bit of offshore wind here and there keeping things clean, but there’s just no power behind it. The energy readings are all low, mostly under 100. It’s a long wait, over a week of this small stuff.

Now, here’s where it gets interesting. We’ve got a standout on the horizon, but it’s a long way out and you need to treat it as promising, not certain. On Monday the 31st of August, a proper south groundswell moves in, with a solid 10ft on the morning and a period of 10 seconds. The energy readings totally blow up, hitting 2183, which is strong to very strong wave energy. The wind is forecast to be offshore from the WNW and clean. This is a case where the swell is just too big for the river mouth, especially for the beginners, and you’d want some serious experience under your belt. The morning is big and powerful, but by the afternoon it drops to 8ft and that’s when it looks excellent for the experienced crew. This is the one to keep an eye on, but it’s over a week away so don’t book the day off yet.

After that, the first of September sees it back off but still a solid 7ft to 8ft, though the winds get a bit messy with some cross-onshore and onshore action, and the energy drops back to the moderate 800s. It’s still far from perfect, but there’s size around. The 2nd of September holds some size, with a 5ft morning and a 8ft afternoon, but the cross-onshore breezes are going to make things lumpy. It’s still a better bet than anything in that first ten days.

So, to sum it up, the first week is a long, flat, and frustrating grind. The only real standout is that big pulse on the 31st, but it’s a long-range call that might get better or worse. If you’re desperate, the small clean windows on the 24th and 27th afternoons are all you’re getting, but honestly, we’re all just waiting for that big one.

Rusty.
