The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Aldinga Beach. I gotta be straight with you – the next couple of weeks are lookin’ pretty grim. We’ve got a long stretch of nothin’ to start, so don’t go waxin’ up just yet.
The first day we see anything worth paddling out for isn’t until Tuesday, the 25th of August. That afternoon, we finally get a little pulse. The swell is weak at 4 ft from the WSW, with a short period of 5 seconds, and the combined swell energy is pretty low at 83. It’s not much, but the wind is glassy, and that’s a major positive. The water temp is about average for this time of year, so no surprises there. You’ll have the place to yourself, as it’s inconsistent, so don’t expect a long session. It’s barely surfable, but it’s the only glimmer on the horizon.
After that, it’s mostly back to nothing. The good news is, Aldinga is a fairly exposed spot, so it tends not to stay this flat for long. Forecasts can change, so keep an eye on it.
Later on, around Friday the 21st of August, a bigger swell rolls in – 6 ft to 7 ft from the WNW, with a short period of 6 seconds and combined energy hitting 230 to 354. That’s moderate energy, but it’s ruined by a strong cross-onshore wind. The waves will be choppy and messy, more suited for a kite than a surfboard. Not worth it for paddle surfing.
The Saturday after that, the 22nd, cleans up a bit with offshore winds, but the swell drops to 4 ft and the period is still a short 6 seconds. It’s cleaner, but the energy is weak (112) and the waves are just average.
Forget the rest of the window. There’s no real standout, no day that’ll get your heart racing. The best you’ve got is that glassy Tuesday afternoon on the 25th, and even that’s a stretch. Hang tight, boys.
Rusty.

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.
