The Lowdown
Alright, Rusty here. Let's talk about the surf coming up. We're looking at Aldinga Beach, and I gotta be straight with you – it's a rough run.
Right from the start, this stretch is looking flat and pretty unappealing for any proper paddle. The whole first week is a write-off for any real waves. We’re talking about tiny, weak swells, with wave energy barely registering. You’re not getting anything rideable. It’s a long, flat spell that runs all the way through to the end of the first week and into the start of the second.
The only real pulse of swell we see on the charts is that big jump around Sunday, September 6th. The combined swell energy is massive, with a swell of about 12ft from the WSW. That’s serious power. But here's the catch – it’s coming in with a strong onshore wind. We’re looking at a fresh to strong cross-onshore breeze, making for a lumpy, messy, and closed-out situation. That size, with those winds, that’s not for beginners. Honestly, on that Sunday, the setup looks far more interesting for a kite surfer than anyone trying to get a clean paddle in. Even on Monday, September 7th, the swell drops off quick and it’s still onshore.
After that big event, we’re back to tiny, weak conditions for the rest of the outlook. There are a few moments with glassy or offshore winds on the mornings of Friday, August 28th, Monday, August 31st, and Thursday, September 10th, but there’s simply no swell to push you along – just knee-high dribble at best. The water temperature is about 58°, which is pretty average for the time of year, nothing weird going on there.
So, the honest call: there are no standout days. This is a blank run for surf. The only real wave event is the big one on the 6th, but it’s blown out. For a spot that’s already inconsistent and only fairly exposed, this is one of those periods where you don't fight it. Forecasts can always change, but right now, it’s a solid wait.

A general guide to surfing at Aldinga Beach can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
