The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
To be brutally honest, this is a tough one. The whole 16-day window is looking like a flat spell for Aldinga Beach. We’ve got nothing but poor surf conditions across the board, with the combined energy of all swells directed here barely registering a whisper, mostly in the single digits or low tens. That’s weak energy, folks. You’re looking at a long dry stretch starting from now, right through the end of the month. The wave heights are barely a ripple, with the swell averaging around 0.3 feet to 1 foot for most of the period. There’s just no push in the water.
The first real hint of anything with a bit of shape comes very late in the forecast. On Friday the 28th of August, we see a pulse of swell. The summary swell height jumps to 6 feet from the WNW, with a period of 6 seconds. The combined energy of all swells directed here hits 266, which is moderate wave energy. But the wind is a cross-shore, not ideal, and the surf quality is still rated as poor. It’s a short-period windswell, so it’ll be a bit bumpy and messy. Still, 6 feet is the only real size on offer, so if you’re desperate, that’s your window. It’s going to be a big, lumpy wave, and at that size, it’s only for the experts.
The offshore winds show up on the mornings of the 26th and 27th, but with almost no swell to work with—0.3 feet—it’s a tease. Glassy conditions on the afternoon of the 26th too, but again, no wave.
Look, I hate to be the bearer of bad news, but this is a proper blank run. It’s one of those periods where the ocean just doesn’t want to play ball. Keep your eye on the forecasts, because things can change, but for now, the board’s staying in the car.
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. 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.
