The Lowdown
Alright folks, let’s get straight into it. Grab a coffee, because I’ve got the full 16-day picture for Aldinga Beach, and honestly, it’s a tough one to swallow.
Right now, and for the next week and a bit, there’s just nothing doing. The swell is tiny, mostly under 3 feet, and the periods are short – we’re talking 4 to 5 seconds, which is just windswash. The energy is weak, with values barely scraping past 20 (13-22). The conditions are poor, with cross-onshore and onshore winds making it a choppy, messy affair. It’s a frustrating start to the outlook.
The first real glimmer of hope doesn’t show up until Sunday, August 2nd, and that’s still a week away. We’ll see a slight bump in swell, with the morning seeing 3 feet from the SW and the afternoon pushing to 4 feet. The period is still a short 5 seconds, but the combined energy jumps to 37 and then 76 in the arvo. More importantly, the wind is a clean cross-offshore from the N. That’s a big deal. Aldinga should be clean and rideable, but don’t expect much power. It’s a beginner-friendly size, so it’s a good one for a learner session.
The standout, and I mean the only one worth circling on the calendar, is Monday, August 3rd. The morning session is looking the pick of the entire 16 days. We’ve got a 3 feet swell from the SSW, with a clean cross-offshore wind from the N at 22 mph. The energy is moderate at 48. It’s the only time the stars align for a decent, clean paddle. The size is manageable for most, but not too big.
Then the wind turns on Monday afternoon, and after that, we’re back to small, onshore, and choppy slop. The very end of the run, on Thursday, August 6th, goes completely flat with zero swell.
So, to sum it up: the first 10 days are a write-off. Sunday, August 2nd, offers a clean, small wave option for beginners. The real call is Monday, August 3rd morning – that’s your best shot for a clean, fun session, but it’s a long way out. Given the short, weak swell, don’t expect any power; it’ll be more of a longboard day.

A general guide to surfing at Aldinga Beach can be found by selecting the local surf guide option on the grey menu. Our Aldinga Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

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.
