The Lowdown
Righto, grab a coffee, pull up a chair. Rusty here with the outlook for Aldinga Beach. Let’s be straight with you, mate – this is going to be a tough stretch for us. The forecast window runs a full 16 days from now, but honestly, we’ve got a long, dry spell coming. There aren’t any proper waves on the cards, and every single time slot in this whole outlook comes back as poor conditions. It’s a grim picture.
We kick off with a bit of a tease. On Saturday the 5th, there’s a 7.2ft to 8.2ft swell from the W and WSW, packing some moderate energy (430 to 628), but it’s completely blown out by a strong 25 mph cross-onshore wind. That’s a mess, not a surf. After that, the swell drops right off. We’re looking at tiny waves under 1.6ft for almost the entire rest of the outlook. Sunday the 6th through Tuesday the 8th offer some glassy or clean windows with light winds, but the energy is next to nothing (single digits to low 30s). The swell on Monday the 7th is 0.7ft and period is a weak 9 seconds. It’s flat, plain and simple. There are a few little clean mornings mid-week around Wednesday the 9th to Thursday the 10th, but the swell size is still tiny, and by then the wind is getting up again.
For the second week, from around the 13th of September onward, we get occasional flat spells with less than 0.7ft of swell and the occasional light glassy period (like Sunday afternoon the 13th and Monday afternoon the 14th), but that’s just a mirror, not a wave. A bit of a bump mid-week on the 15th with a 2ft NNW windswell shows up, but it’s lumpy with a 16 mph cross-shore. Far from it.
Truth is, this beach is rarely breaking for the entire forecast period, and when it does, it’s blown out or tiny. It’s a blank run – about as normal as it gets for the area when the wind and swell don’t line up. Don’t bother packing the board just yet.

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.
