The Lowdown
Right then, let’s have a look at what’s on offer for Aldinga Beach. I’ve gotta be straight with you – the next couple of weeks are looking pretty quiet. There’s a real gap here, with no proper surf to speak of for the first ten days or so. The swell is tiny, the wind is mostly onshore or cross-shore, and it’s a tough stretch for anyone wanting to get a wave.
The first sniff of something that might get your heart beating arrives on Thursday the 20th of August. There’s a late-developing swell that morning, pushing up to 6ft from the west, but the period is a short 6 seconds, so it’s going to be a bit lumpy. The combined energy is moderate at 279, and the wind is offshore from the north, which is a big tick. The water temp is about average for this time of year, so it’s not going to be a shock. For a beginner, that 6ft is getting a bit much, but for the more experienced crew, it could be a bit of fun. The swell direction is SW, which is pretty much the optimum here, so that’s a good sign. It’s a fairly exposed beach, so it’ll pick up whatever is out there.
After that, it drops off again quickly. The Friday the 21st has a little bit of leftover swell, but it’s small. The rest of the run into the end of the month is mostly flat with only a few inches of wave, even with a few clean, glassy mornings. The wind stays cross-offshore a lot, which is perfect for clean conditions, but there’s simply no swell to ride.
Overall, the only standout is that Thursday the 20th of August morning. It’s not a world-beater, but it’s the only real chance of a wave with clean offshore wind. The rest of the window is a write-off, so don’t plan your week around it. If you’re desperate, you might get a little knee-high thing on the Tuesday morning the 18th when it’s glassy, but it’s a real long shot.

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.
