The Lowdown

Alright, Rusty here. Let's have a look at what's cookin' for Aldinga Beach.

Honestly, I gotta be straight with you – the next two weeks are a real struggle. The surf is flat, and the models are showing nada for a good, long stretch. We're talking day after day of tiny, weak waves that aren't even worth paddling out for. There's a big gap of surf starvation from now all the way through to the 25th of August. You'll be looking at a lot of clean, glassy water, but with swell so small it’s barely a ripple. You get the odd moment of glassy conditions, like on the 20th with a calm sea, but with a 1ft swell from the NNW that has a period of only 3 seconds, it's just not surfable.

Then, hold onto your boardies, because out of the blue on Wednesday the 26th of August, the ocean finally wakes up. The morning session sees a solid 6ft swell rolling in from the WSW with a combined energy of 226, which is solid moderate energy. The wind is a moderate breeze from the north, keeping things clean. This is the one and only standout in the whole outlook. Now, the swell period is only 6 seconds, so it's windswell, not groundswell, which means it'll be a bit crumbly and sectiony rather than the long, peeling lines we'd love. Still, after all that flatness, 6ft and clean is a bloody welcome sight. If you're an expert, you could get something, but it'll be a bit of a mess. For beginners, it's a no-go as it's over 5ft. The afternoon sees it drop back to 4ft with crossing winds, so the window is tight.

So, to sum it up: a whole lot of nothing for two weeks, then a brief, one-morning pulse of swell. Don't plan your life around it, but keep an eye on the morning of the 26th. After that, the forecast goes quiet again. That's the hand we've been dealt.

Information about the Aldinga Beach Surf forecast

The above surf forecast table for Aldinga Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. 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.
