The Lowdown
Alright, let me get my head around this. I’m looking at Aldinga Beach here, and to be honest, it’s one of those stretches where the surf just doesn’t turn up much. Over the next two and a half weeks, the swell is tiny, barely pushing 2ft at best on the odd afternoon, and the rest is flat – 0.3ft to 1ft dribble. The wind, though, has some moments: we get glassy spells on the morning of Wednesday the 16th with zero wind, and again on the afternoon of Monday the 21st. But you can’t ride what isn’t there.
The first real sniff of something rideable doesn’t appear until Tuesday afternoon the 22nd, where we finally see a brief window: 4ft of swell from the W, but with a short period of 4 seconds – that’s just windswell, no grunt, no shape. It’s glassy though, which is a major positive. That’s basically a one-off. The water temperature sits around 59° initially, with an anomaly of just 0.7°, so it’s about normal for the time of year – a little cool, but expected.
Now, the combined wave energy for that little pulse on the 22nd is weak, coming in at only 44, which matches the tiny swell. The whole run is pretty poor. The spot is inconsistent by nature, and this outlook proves it. There’s a gap of flatness from now all the way until that Tuesday afternoon, so over a week with nothing worth paddling for. After that, it drops back to tiny junk through to the end of the period.
Honestly, if you’re not fussy and just want to sit out in the sun on a board, the glassy afternoon of Tuesday the 22nd with that 4ft is your only chance, and even then it’s tiny and weak. For anyone else, this setup looks more interesting for kite surfing than paddle surfing – there’s just not enough push.
Stay tuned, though. It tends not to stay poor forever.

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.
