The Lowdown
Alright, Rusty here. Let's chew the fat on what's coming down the line.
Honestly, this is a grim outlook for Aldinga Beach. The entire 16-day run is a bust. Every single forecast is labeled "poor surf conditions," and the quality scores are all zeros. There just isn't a wave worth paddling for.
It starts on Tuesday, the 4th of August, with a tiny 1ft swell from the WSW, weak and onshore with almost no energy. Wednesday and Thursday are equally flat, with swell barely making it to 1ft and a short period that lacks any punch. The winds are messy, mostly cross or cross-onshore—nothing clean.
We see a spike on Sunday, the 9th of August, with swell jumping to 6ft in the morning and nearly 8ft by the afternoon, all from the west. There's some real power in the water, with combined energy readings of 172 and then 537. But here's the kicker: the wind is howling onshore at 25 mph, making it a lumpy, wind-blown mess. By Monday the 10th, it's still 6ft to 4ft of slop. This isn't for a surfboard; it's kite-surfing conditions with that strong cross-onshore breeze and all that chop.
Tuesday the 11th of August is the biggest swell of the period, with 10ft of WSW energy and a combined energy over 1000 (1020 to be exact). But again, the wind is screaming onshore at 25 mph, and the period is a short 8 seconds. That's just a washing machine. Experts only, and even they'll be in for a beating.
After that, it fades fast. The second week, from the 13th of August onward, is back to nothing. Swell drops to 1ft or less. There is a brief moment on Monday morning, the 17th of August, with 0.7ft and glassy conditions—dead calm wind. It'll look pretty, but there's no water to push you.
So, the short of it: no standouts here, no good days. It's a flat, windy 16-day stretch. This kind of dry spell happens now and again for this spot—just one of those times the ocean is saying 'no'.
Keep your board in the car just in case, but don't hold your breath.
Rusty.

A general guide to surfing at Aldinga Beach can be found by selecting the local surf guide option on the grey menu.

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.
