The Lowdown
Alright folks, Rusty here. Let’s be straight with you about Aldinga Beach. We’ve got a full 16-day window ahead, but honestly, there’s nothing to get excited about for a while.
The first thing you need to know: there’s basically no surf on the cards for the best part of two weeks. The first week and a half is a total write-off. We’re talking tiny, gutless waves day after day. The combined energy of any swell is in the single digits, barely registering. It’s a flat spell, plain and simple.
The only real pulse of swell we see is way out on the horizon, around Monday, September 7th. The chart shows a sudden jump in the combined energy to 384, which is a solid, moderate push of energy. We’re looking at a 7ft swell from the West, but with a period of only 7 seconds. That’s a short-period, wind-driven swell, not a clean groundswell. And here’s the killer: the wind is cranking onshore from the WSW at 22 mph. That’s going to make it a messy, blown-out, ugly day. Anything over 8ft is expert-only, and this is close to it, but with that wind, only the most experienced, and maybe the kitesurfers, will be having any fun. The water temperature at the start of the period was 58°, which is bang on average for the time of year.
So, the short of it is: put the board away. There is no standout session in this forecast. It’s a long, flat run with one choppy, windy day at the very end that’s more of a warning than a recommendation. We’ll see if the forecasts change, but right now, it’s a no-go.

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.
