The Lowdown
G'day, I'm Rusty. Let me break it down for Aldinga Beach. To be straight with you, the next 16 days are a total dud for surfing. There's nothing on the horizon that’ll give you a decent wave, and the whole stretch is a flat spell. The water temp is 58°F, which is about normal, so no surprises, but you’ll be staring at a mirror-flat ocean.
We start on Friday, August 28th. A tiny 0.3ft southwest swell rolls in with a very long 16-second period. That long period just washes through a beach break without forming, leaving nothing to ride. It's glassy in the morning, so it looks nice, but there's no energy—the combined energy reading is just 15. That same story holds through the weekend and into the start of the week: swell heights barely move, and energy drops to 4 or 1 in the later sessions. It's dead.
Heading into September, the 2nd and 3rd see a bit of a bump to 2ft to 4ft, but the period is a short and weak 4 to 5 seconds. The wind goes cross-onshore with moderate breezes, chopping up what little there is. The energy hits 62 on the 3rd, but that's for a 4ft wind-swell with that short period and bad wind—it's messy and more of a kite-surfing situation than a paddle session.
After that, it's back to flat. There's a run of blank days with no swell at all on the 8th and 10th. On September 11th, we get a whisper of a 0.3ft southwest groundswell with an 18-second period, giving a combined energy of 23. It’s clean with a cross-off wind in the morning, but the swell is essentially zero. It's just not there.
So, look, there are no highlights, no best sessions. For this area, a flat run like this does happen. It’s one of those spells where you just have to wait it out and check back when the forecast shifts.

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.
