The Lowdown
Alright fellas, Rusty back on the mic. We’re looking at Aldinga Beach, and I’m gonna level with you – it’s a tough outlook.
We’re kicking off with a real flat spell. From now through the first week of September, it’s basically a lake. Tiny waves, combined energy down in the single digits. The spot is inconsistent by nature, so a run like this is pretty standard for this area. Don’t bin your gear yet; the forecast can flip, but there’s nothing to get excited about for a while.
We finally get a pulse of life on the 6th of September, Sunday. The afternoon shows a bump of west swell around 3ft with clean sideshore wind. The combined energy hits 45, which is weak, but at least it's something. Then things get a bit more interesting on Monday, the 7th of September. The west swell pushes up to a clean 5ft, and the combined energy climbs to 125 – that's real moderate energy, enough to get a proper session in. The downside is the wind goes side-offshore in the morning and turns cross-shore in the afternoon, putting some texture on the waves.
If you’re picking a moment, Monday morning (7th September) is your only real standout. That 5ft west swell with clean sideshore wind will have some push. The period is only 6 seconds though, so it’s short-period, wind-driven stuff. It’ll have energy, but it won’t be smooth and lined up like a proper groundswell. It’s a bit of a handful for beginners at that size, and not quite big enough for the experts to really get lit up. The water is sitting right around 59°F, which is normal for this time of year.
Tuesday the 8th of September cleans right up, glassy in the afternoon on a tiny 2ft west swell – that’s strictly a log session. After that, it looks like we drift back into another quiet stretch.
So, to wrap it up: one solid morning in the middle of the second week. That’s your window. Don’t plan your life around it, but if you’re free, get out there.
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. 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.
