The Lowdown
Alright, Rusty here. Let’s take a look at what’s coming up for our patch.
Alright, straight up, we’ve got a bit of a flat spell to get through first. For the first week or so, there’s barely a ripple worth paddling for. A few tiny waves show up here and there, but the conditions and wind just aren’t playing ball. You’d be wasting your time. It’s not until Thursday, August 13th that things start to get interesting, and even then, it’s a slow build.
The standout window is shaping up to be Saturday, August 22nd. That morning is the one to circle. We’re looking at a solid 8ft swell from the S, and with a light breeze making it glassy offshore from the SSW, the surface is going to be clean as a whistle. The wave energy is pumping hard (1824), so this is proper, powerful groundswell. Keep in mind, at that size, it’s advanced territory. The break is Shark Island (Cronulla), a reef setup that handles a south swell well. The gusty cross-off winds we’ve been dealing with will finally ease up, giving us that clean, lined-up look. This is your best bet, but expect a crowd – it’s a peak that can get busy when it’s on.
Leading into that, there are a couple of sessions worth keeping an eye on, though they come with caveats. Thursday, August 13th afternoon sees a jump to 8ft from the S with a decent period (11 seconds) and fresh offshore winds (WSW at 19 mph). The wave energy is strong (1365), but the forecast calls it marginal, maybe due to tide. Still, for the experienced crew, that’s a session to have on your radar. Friday, August 14th holds similar size into the morning, with a long 12-second period, but again, there’s a question mark over the quality.
After that peak on the 22nd, the swell drops off pretty quick into ordinary, small surf again towards the end of the window. Don’t get fooled by the big numbers on the 21st – it’s an ENE swell with onshore or cross-shore wind, so it’ll be a messy, lumpy mess at Shark Island.
Overall, if you’re patient and can wait it out, the 22nd is the only real standout. The rest is a write-off or just for the die-hards.
Stay frothing.
