The Lowdown
Alright folks, Rusty here. Let's take a look at what we’ve got on the cards for Aldinga Beach over the next couple of weeks. I'm not gonna sugarcoat it – this is a tough stretch of forecasts.
The big picture for Aldinga Beach is pretty bleak for the most part. We've got a long, long stretch of tiny, weak, and often messy surf. You’re looking at a solid week and a half of days where the swell is barely a ripple. The combined energy of all swells is pitiful, mostly sitting in the single digits or low teens – that's about as weak as it gets (energy under 100). For those keeping score, that means very little to get excited about on the paddle out.
We start off on Friday, September 11th, with nothing. Saturday and Sunday, September 12th and 13th, are more of the same – tidbits of swell but with onshore or cross-shore winds that ruin any chance of a decent wave. Honestly, for the first nine days, there is simply no surf worth paddling for. It's a blank run.
Now, let’s talk about the one glimmer of hope. This comes to us almost out of nowhere. Towards the end of the period, on Sunday morning, September 20th, we see a sudden pulse of swell roll in. That morning, the combined energy jumps way up to 388 (moderate wave energy), with a 7ft swell from the W. The wind is glassy from the SSE – just dead calm. That’s a rare and beautiful thing around here. However, that swell period is only 7 seconds, so it’s a short-period, wind-driven sort of wave, not a long-period groundswell. It'll be a bit fat and quick, but with that glassy surface, it could be the one session to get wet.
The water temp is sitting at 59°, which is pretty much exactly what you'd expect for this time of year – no surprises there.
That Sunday morning is the real standout for the entire 16-day window. Monday the 21st drops right back to tiny conditions. After that, it’s back to the small stuff for the rest of the run.
If this was a beach-and-reef setup, I'd say it's looking more like a kiteboarding window. But Aldinga is a beach break. For us paddle surfers, it’s all about patience. Be ready to move on that Sunday morning session, because that’s your best – and only – real shot for the foreseeable.
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.
