The Lowdown
Alright folks, Rusty here, looking at the 16-day outlook for Aldinga Beach. I've got to be straight with you—it's a tough stretch ahead. There's no surf to get excited about for a solid chunk of time, so let's talk about what we're dealing with.
The whole 16-day window is a flat, quiet run. Right from Monday the 14th of September, it's tiny. We're looking at swell heights mostly between 0.3ft and 3ft, and honestly, most of it is just straight-up poor. The combined wave energy barely gets off the ground, often measuring in the single digits or low teens (3 to 37). It's not doing anything.
Aldinga Beach is inconsistent at the best of times, and this forecast confirms a long blank spell. There's a slight bump in energy on Sunday the 20th of September afternoon with a 4ft swell from the WNW, but the period is a short 5 seconds and it's accompanied by onshore wind. That's not surfable, it's just chop. For the rest, we’ve got calm, glassy mornings late in the period (Thursday the 24th and Friday the 25th of September) but with swell heights of 0.3ft to 1ft and energy readings around 4 to 36, there's simply no wave to ride.
The water temp sits at about 59°F, which is 1°F warmer than average for this time of year—nothing unusual there. But without any swell, it doesn't matter how warm it is.
In plain terms: there is nothing on offer. No standouts, no hidden gems. The surf is flat, the small bumps are messy, and the wind is often cross or onshore. This is one of those periods where you don't even bother checking the ocean. It's a normal dry spell for this area, and we just have to ride it out. Hopefully, the long-range charts will start looking more interesting.
Until next time,
Rusty

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.
