The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – it’s a pretty bleak stretch ahead for Aldinga Beach. The overall pattern is flat and forgettable, with a whole lot of nothing for days on end. You’re looking at a gap of nearly two weeks before anything even remotely worth paddling out for shows up.
Starting off, Friday the 4th of September and Saturday the 5th are a write-off. That tiny 1ft swell from the WSW on Friday is just too small to bother with, and Saturday gets hammered by a strong 25 mph cross-onshore wind whipping up a messy 7ft windswell with a short period of 7 seconds. The combined energy of all swells directed here hits 447 (moderate to strong), but it’s all junk – messy, stormy, and best left alone. Sunday the 6th through to Wednesday the 16th of September is a flat spell, with swell heights barely flickering above 1ft and energy values mostly in the single digits or low double digits. Winds are all over the place, but it’s just not enough ocean to work with.
Now, here’s the one glimmer. Wednesday the 16th of September afternoon sees a bit of life. We get a 4ft swell rolling in from the WSW, with a period of 5 seconds, and the wind goes glassy – just a 3 mph SSW breeze. That combination is rare and it’ll clean things right up. The combined energy is 75 (weak), but for Aldinga Beach (South Australia), that’s about as good as it’s going to get. The water temperature is about average for this time of year, so no surprises there. The break is inconsistent and exposed to the SW swell, which is the optimum direction, so there’s a chance for a few fun ones if you’re patient. Crowds are often an issue here, so expect company.
After that, Thursday the 17th of September kicks up a bit more size – 6ft to 6ft from the WSW, but with a short 6-second period and a moderate cross-shore breeze making it chop. The energy jumps to 259 (moderate), but the quality is poor. That’s a bit too big and messy for the average punter, and really only worth a look if you’re an expert chasing something punchy. By Friday the 18th and Saturday the 19th, it fades back to tiny, limp leftovers.
Bottom line: the standout is Wednesday the 16th of September afternoon. Glassy conditions, a clean 4ft swell, and the best chance for a proper surf in a long, flat run. It’s not a classic, but it’s the only one on the table.
Rusty.

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.
