The Lowdown
Alright mates, Rusty here. Let’s break down Aldinga Beach for the next couple of weeks. It’s gonna be a quiet one.
For the whole 16-day stretch, we’re looking at a real dry spell. The first week and a half are flat, with no real surf to speak of. Things don’t even try to show up until the 22nd of August.
On Saturday the 22nd of August, we finally see a little bump. The swell gets up to about 3ft from the west, but it’s a short-period wind swell – only 5 seconds. The combined energy is still weak (49). The real killer is the wind, which is a fresh cross-shore breeze at 18 mph, making it lumpy and choppy. For a beach break, this is way more suited to kite surfing than a proper paddle session.
Water temp at the start is 57°, which is normal for this time of year.
Other than that, the rest of the period is tiny – often less than 1ft. There are some clean, glassy mornings (like the 20th of August), but with no swell to ride, it’s just a pretty view. Even when the wind goes offshore on the 17th and 18th of August, the swell is only ankle-high.
This is a common quiet period for the area. Forecasts can change, but for now, keep your board in the car and your expectations low.
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.
