The Lowdown
Alright, listen up. Rusty here with the outlook for the stretch ahead.
Honestly, mate, this is a tough one to call. The next couple of weeks are looking flat as a tack. We’ve got nothing on the cards at all for Aldinga Beach. The whole sixteen-day window is a write-off with no decent surf to speak of. The combined swell energy barely gets off the ground, maxing out at a paltry `67` (weak) on the first morning and dropping to single digits after that. You’re looking at long gaps of days with absolutely no recommendations.
The water temp is sitting at `58°F`, which is about average for this time of year, so no wetsuit-related surprises there.
Tuesday the 25th starts us off with a meagre `4ft` of short-period `SW` wind swell, but it’s completely blown out by a `S` wind at `16 mph`. It’s messy, choppy, and not worth getting damp for. After that, it’s all sub-2ft junk with period so short it’s barely a ripple. We get a few glassy pockets on Wednesday the 26th and Thursday the 27th, but with only `0.7ft` on offer, it’s a lake, not a surf break.
The second week? Don’t hold your breath. More of the same – tiny, weak, and poor. There’s a little bump of `3ft` from the `NNW` on Monday the 7th of September, but the period is a short `4` seconds and the cross-shore wind spoils the party. Even the cleaner days with light offshores can’t do anything with the non-existent swell.
For a spot that’s already inconsistent, this is a proper blank run. If you’re desperate for a paddle, you might find a ripple on a glassy day, but for surfing... forget it. Forecasts can always change, but right now, the boards are staying in the garage.
Rusty.

Information about the Aldinga Beach Surf forecast
The above surf forecast table for Aldinga Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Aldinga Beach can be found by selecting the local surf guide option on the grey menu. Our Aldinga Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Aldinga Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
