The Lowdown
G'day, Rusty here. Look, I'm gonna be straight with you – for this stretch of coast, we're in for a long, flat spell before anything worth getting wet for shows up. Don't get your hopes up too early.
The first two weeks of this outlook are a write-off. From Wednesday the 26th of August through until Friday the 4th of September, Aldinga Beach is seeing next to nothing. We're talking tiny dribbles of 0.3ft to 0.7ft almost every day, with combined swell energy barely ticking over, often below 20. The wind might be glassy or clean on some mornings – like Thursday the 27th with a light north-northwest cross-off – but there’s simply no swell to work with. It’s a total flat spell.
The water temperature at Aldinga Beach is sitting at 58°F with a tiny anomaly of 0.4°F, so pretty average for this time of year.
Now, there's a little flicker of life on Saturday the 5th of September. We get a lumpy 10ft swell from the west-southwest early, but with a short period of only 8 seconds and a cross-shore wind, it's messy. The real standout, though, is Saturday afternoon. The wind goes glassy, the swell drops to a still-chunky 6ft from the west-southwest, and the combined energy jumps to 293 – that's moderate energy. It's the only window in the whole run that looks surfable.
For the rest of the second week, it’s back to small, weak, and mostly onshore or side-off conditions. There’s a brief spike on Tuesday the 8th of September with a 5ft swell, but a 19 mph south cross-on wind and lumpy 179 energy makes that more of a windsurfing or kiting scene than a surf session. Not for paddle surfing.
So, if you're hanging for a wave, circle Saturday the 5th of September afternoon at Aldinga Beach. Glassy conditions and a solid 6ft swell from the west-southwest – that's your best and really only bet in this 16-day window.
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.
