The Lowdown
Howdy folks, Rusty here. Let’s talk about the outlook for Aldinga Beach.
I’ll be honest, this one’s a tough read. The whole 16-day stretch is pretty much a dead loss for good surf. There’s not a single solid recommendation in the cards. We’re lookin’ at a long, dry gap of days where the ocean is just not cooperating. It’s one of those spells where the forecast is flat and uninspiring.
The first bit of proper size doesn’t show up until the very end of the period. Come Saturday, August 8th in the afternoon, a quick injection of 8ft west swell hits, with combined energy at 494—moderate power. But the period is short at 7 seconds, and the wind is a messy cross-onshore. That’s chop city. Honestly, this looks more like a kiteboarding session than a surf. Not worth paddlin’ out for.
The biggest day is Sunday, August 9th. The morning brings 8ft west swell (474 energy), and the afternoon jumps to a serious 10ft from the WSW, with combined energy reading a strong 1148. The wind is cross-offshore both sessions, so the surface will be clean, but that’s a heap of water. 10ft with a short period is pure grunt—experts only. That kind of size and power at a beach break will close out and churn. Not a beginner’s playground by any stretch.
Before all that and after, it’s tiny dribble. We get a glassy morning on Tuesday, August 4th, but with waves barely a foot high. The water’s about 58°F on the Wednesday, which is par for the course around here.
So, the bottom line is: Aldinga Beach is a flat patch. If you’re keen on a big, messy challenge, the 9th is your only look, but it’s not for the faint of heart. For everyone else, I’d hang the wetsuit up for a couple weeks and keep an eye on the charts.
Rusty.

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Aldinga Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
