The Lowdown
Alright folks, Rusty here. Let's have a look at what Aldinga Beach has in store for us over the next couple of weeks. I gotta be straight with you – this is a real quiet stretch on the surf front. We're looking at a long run of very small energy with barely a wave worth paddling for. The first half of the outlook is essentially a write-off for any kind of real surfing, and while there are a few flickers of life near the end, they’re pretty weak tea. It’s the kind of setup where you’d be better off checking inland or just taking a break from the salt.
Right from the start this Saturday the 12th, it’s tiny. We're talking 0.3ft of super long period swell (16 seconds), but it’s from the SW and the overall wave energy is bottom of the barrel at just (10). There’s literally nothing to get excited about. This flat spell just goes on and on. Through Sunday, Monday, Tuesday and deep into the week, we see the same story: 0.3ft to 3ft of short, weak windswell. The winds are messy, often cross-onshore, and the energy stays in the low single digits to maybe 35 at best. It’s a total scratch.
We finally get a slight pulse of interest on Monday the 21st of September. The swell bumps up to a whole 4ft from the WSW, with the period dropping to 6 seconds. The combined energy nudges up to (85) – still weak but at least it’s something moving. The downside is we’ve got a gentle cross-onshore breeze, which will put a bit of a chop on the surface. This is a beach break and with that wind, it’s not going to be clean. Honestly, with that short period and onshore wind, it might look more appealing to the kite crew than us paddle surfers.
The best chance for a clean wave comes on Tuesday the 22nd in the morning. We get an offshore breeze from the ENE at only 3 mph, and a 1ft swell from the WSW with a 9-second period. The energy is still low at (32), but that offshore wind over a longer period swell means it will be glassy and clean. It’s tiny, but if you’re desperate for a log or a longboard, this is your window. For the rest of the forecast, it’s back to flat and windy.
So, to sum it up: the entire 16 days is a surfing drought. There’s no standout quality session. The only mentionable period is the morning of Tuesday the 22nd for the clean conditions, but the wave size is tiny. If you don’t have a longboard, don’t even bother. For the rest of it, the wind is too strong and the swell is too flat.
