The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Aldinga Beach over the next couple of weeks.
Honestly, I've got to be straight with you – it's a pretty bleak outlook. The finder is throwing up a whole lot of nothing for the entire 16-day window. Every single day, every single session, comes back with poor surf conditions. There's no standout, no hidden gem, nothing to get excited about. We're looking at a long, dry spell with no real surf on offer.
The water temp at Aldinga is sitting at 58°, which is about average for the time of year, so no surprises there.
We get a bit of a pulse on Sunday the 9th of August, with a 7ft to 8ft swell from the west, but the wind is howling onshore from the WSW at 22-25 mph, making it a total mess. The combined energy jumps up to 324 and 542, so there's power, but it's unrideable. That setup would be far more interesting for a kite surfer than a paddle surfer. After that, it drops off again quickly into tiny, weak leftovers.
The following week is just as bad. A few glassy mornings on the 15th and 16th of August, but with swell heights of 0.3ft, you're just floating. There's a tiny 3ft pulse from the NW on the 19th of August, but it's only a 5-second period, so it'll be weak and crumbly. The onshore breezes and cross-shore winds just keep ruining any chance of a clean wave.
It's one of those blank runs that's more normal for this area when the swell windows don't line up. Keep your hopes up, though – it tends not to stay this poor for too long, and forecasts can always change.
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.
