The Lowdown
Alright folks, Rusty here with a look at what’s on offer down at Aldinga Beach. I’m going to be straight with you – it’s looking like a long dry spell. We’ve got a solid 16-day window on the cards, but for the vast majority of it, you’ll be staring at a flat, glassy lake.
The first real chance of anything surfable doesn’t show up until Wednesday the 23rd of September. That’s a good stretch of days with almost nothing doing. Before that, we’re talking about waves you can barely measure – 0.3ft at best, with combined swell energy barely ticking over (as low as 1, never above 30). There'll be plenty of clean, glassy mornings, but no wave to surf, just a pretty view.
Wednesday the 23rd is our one and only standout, and it’s not exactly a world-beater. We finally see a little pulse from the SSW, pushing the swell up to 4ft. The period is a short, dumpy 5 seconds, so it’s not got much push, but the combined energy is the highest we’ll see at 99. The real good news is the wind: it’s due to be glassy in the morning and afternoon. That means the surface will be clean, which is a major positive for such a small, weak wave. It’s surfable, but only just.
The water temp is sitting at 59°, with an anomaly of 0.7°, so it’s pretty much what you’d expect for this time of year. The wind for that Wednesday is light, so a 3/2 wetsuit should be fine.
For the rest of the period after that, it’s back to the same story. Thursday the 24th drops back to 3ft and the energy disappears. It’s just not on.
So, the takeaway is this: we have one day, Wednesday the 23rd of September, that might just be worth a paddle if you’re desperate. The swell is small and weak, but the glassy conditions will make it as good as it can possibly be for a 4ft, short-period bump. Other than that, you may as well take the board bag off.
Keep an eye on the charts; it tends not to stay this poor forever.
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.

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.
