The Lowdown
G’day, it’s Rusty.
Let's cut to it—Aldinga Beach has got nothing on offer for the next two weeks. The entire 16-day window is a blank run. No good surf, no proper swell, no clean rideable waves. That’s the long and short of it. But don't get too down; this stretch of coast can go quiet like this, and it won’t stay poor forever. Forecasts change.
Right now, and through the end of August, it's tiny. Swell’s down around 0.3ft to 0.7ft, coming from the WSW. The energy readings are in the single digits, which is about as weak as it gets. There are a couple of glassy mornings—the 28th and the weekend—but you’re looking at ankle-biters with no push. It’s flat, mate. The 2nd of September starts to see a bit more west swell, but the period is a shocking 3 seconds. That’s not surf, that’s just bump, and the wind turns onshore and messy.
Around the 5th and 6th of September, we get a real pulse of size. It jumps to around 5ft to 8ft from the west and WSW. The energy reading hits 735, which is strong, but the period is short—a windswell, not a groundswell. The wind on those days is howling onshore and cross-onshore, 35 km/h, turning the ocean into a lumpy mess. For a beach break, that’s just closeout chaos. More of a kite-surfing day than a paddle-surfing day, if you ask me. And definitely not for beginners at that size.
After that brief punch, it fades quickly. Early the next week, there's some cleaner wind, but the swell is back down to around 4ft to 4ft with a useless 5-second period—just sloppy little bumps with no power. By the 9th and 10th, it’s all gone again, back down to tiny 0.7ft leftovers.
So, the honest truth is, there is nothing to get excited about. The blank run starts now and runs the whole 16 days, apart from that one brief, windy, onshore 8-foot pulse that’s more about power than quality. If you’re desperate, keep an eye on the charts. But for now, leave the board in the shed.
Rusty.

Information about the Aldinga Beach Surf forecast
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.
