The Lowdown
Alright folks, Rusty here. Let's take a look at what's on the cards for Aldinga Beach over the next couple of weeks.
Straight up, the news ain't great. We're looking at a long, dry spell with essentially no proper surf on offer. The entire 16-day window is a write-off, and there's a massive gap right from the start with no real waves to speak of. The first few days are flat, and even when we get a bit of size, it's just not gonna come together.
The only time the swell pushes up at all is around the 3rd of September, with a WSW swell hitting 5 ft Thursday morning. The combined energy is moderate at 146, but it's a short period of 6 seconds, so it's gonna be weak and messy. Wind is onshore from the WSW at 12 mph, which will just chop it up. It's a beach break, and with that combo, it's honestly looking more interesting for the kite surfers than us paddle surfers.
Then there's a pulse on the 8th of September, another bit of swell from the SW at 5 ft, but again, a short 6-second period and a fresh cross-onshore wind from the SSW at 22 mph. That's lumpy, choppy, and plain ugly. Not a standout, not even close.
The water temp is sitting at 58°, which is about normal for the time of year, so no surprises there.
The bottom line? There's nothing to get excited about. Aldinga is a fairly exposed spot, but it's also inconsistent, and this forecast is a classic example of a blank run. It happens. Don't get too down, though—forecasts can change, and it won't stay this way forever.
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.
