The Lowdown
Alright folks, Rusty here. Let's have a look at what Aldinga Beach has in store for us over the next couple of weeks. I gotta be straight with you, it’s looking quiet.
Right now, and for the next week and a half, Aldinga Beach (South Australia, if you're wondering) is basically flat. We're talking tiny dribbles of swell, mostly under 1 foot, with a combined energy reading that’s barely a whisper – mostly single digits or low twenties. That's not much more than a lake paddle. The water temp is sitting at 58°, which is pretty normal for this time of year, so no dramas there, but there's just no energy to work with.
We do get some glassy conditions early on Wednesday the 26th of August, and again on the morning of Friday the 28th, but with the swell being a paltry 0.3 to 0.7 ft, it’s just not surfable. It’s a long, flat spell with only the faintest hope of a ripple.
Now, things get interesting way out in the forecast. On Monday the 7th of September, a pulse of swell finally shows up. We’re looking at a solid 7 ft swell from the WSW, with a strong wave energy of 352 – that's a real kick in the pants compared to what we've seen. Be warned though, that size is getting up there; it’s going to be too big and powerful for beginners, and even for a lot of regulars, the 6-second period means it’ll be a bit messy and fat. The morning has a fresh cross-offshore wind which will keep the faces clean though.
The standout window, if there is one, looks to be Monday the 7th of September afternoon. The swell drops a touch to 6 ft, still a solid size, but the wind goes gentler from the NE, staying cross-offshore. The energy is still massive at 302. This is the pick of the period for the experienced crew. It's big, it's raw, and it's been a long time coming. Just be aware, it can get crowded here, so expect to share the lineup if you're out there.
After that push, it drops off again quickly. By Tuesday the 8th, it's back to small, lumpy onshores. So don't blink, because the surf window is tight.
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.
