The Lowdown
Alright folks, let’s have a look at what’s coming up. I’ll be straight with you – this is a tough forecast. We’ve got an inconsistent, beginner-oriented spot here, and the whole 16-day window is a real struggle.
Aldinga Beach is the only break in the picture, and across the entire period, every single session is marked as poor surf conditions. There’s just no good surf on offer. The first few days – from Saturday the 22nd of August right through to the end of the month – are tiny, with swell heights mostly between 0.3 ft and 0.7 ft. The combined energy is weak, often in single digits or low teens (19 is the highest early on). That’s barely a ripple.
The only real lift in size comes around Tuesday the 25th of August, with a bump to 2 ft in the morning and 3 ft in the afternoon. But the wind is a cross-onshore breeze from the south at 15 mph, turning it choppy. The swell period is a short 3 to 5 seconds, so there’s no real push. The combined energy hits 44 – still in the weak range. It’s a messy, low-quality wave.
We get a few glassy mornings here and there – like Wednesday the 26th and Friday the 28th – but the waves are literally 0.3 ft. Not surfable. The rest of the run into early September is the same story: small, weak, and mostly poor. The best you can say is that on the 2nd and 3rd of September there’s a tiny 0.7 ft swell with a clean offshore wind, but it’s still nothing to get excited about.
Water temperature at Aldinga Beach is 58°F, which is about average for this time of year – that anomaly of -0.4°F is nothing unusual.
Bottom line: there’s nothing worth paddling out for. This is a lean run for the area, and an inconsistent setup like Aldinga Beach can go quiet for long stretches. Hang in there, forecasts can change. But for now, stay dry.

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.
