The Lowdown
Alright, grab a cold one, let's have a yarn about Aldinga Beach. It's gonna be a tough stretch for us South Aussie surfers. Straight up, the charts are showing nothing good for the next two and a half weeks. We’re looking at a long, flat, and frustrating period.
We kick things off on Wednesday the 16th of September, and it’s a dead loss. No energy coming in. That little pulse is a weak, 0.7ft swell from the WSW with a period of 9 seconds, giving a combined wave energy of just (15). That’s barely a ripple. Water temp's sitting at 59°, which is bang on average for this time of year, so nothing weird there.
We drift through Thursday and Friday the 17th and 18th, and it’s the same story – surfable waves? Forget about it. The swell drops even lower, the wind is messy from the north, and we’re not seeing anything worth paddling out for. You might as well wax the car instead of the board.
Come Sunday the 20th, there’s a tiny blip on the radar. A 3ft swell from the NNW shows up on the Sunday morning, but with a period of just 5 seconds and that combined energy sitting at only (37), it’s a weak, choppy mess. The cross-shore wind from the NNW at 15 mph will tear it to shreds. It’s a write-off.
For the rest of the week and through to the start of October, it's just more of the same. We see a couple of sessions late on the 22nd of September with a clean offshore breeze from the east, but with a 0.7ft swell, it's still flat. Absolutely flat. There’s nothing to ride.
Don’t even get me started on the final few days of September and into October. The wind cranks up from the west and southwest, 15 to 19 mph, and all we get are tiny, onshore slop. With such insignificant swell and rough conditions, this setup looks more interesting for kite surfing than paddle surfing.
Honest truth? The best move is to keep the board in the rack and wait. It tends not to stay this poor for long, and the charts can turn around quick, but right now there ain't a single wave worth mentioning in the whole 16-day window.
Stay tuned, Rusty.

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.
