The Lowdown
Alright, grab a seat. Rusty here. I’ve had a good look at the charts for the Aldinga Beach region, and I’ll be straight with you – it’s a tough stretch. The next 16 days are looking like a proper write-off for any decent paddle surfing. The finder isn't giving me a single recommendation to work with, so we’re looking at a blank run from start to finish.
The issue is a serious lack of swell. For the first week and a half, we’re talking tiny, wobbling lines – mostly around 0.3ft to 1ft with weak, short-period energy. The combined energy is barely registering, often single-digit numbers (like 5 or 15), which is about as weak as it gets. The wind is a mixed bag but doesn't matter when there's nothing to ride. On the 25th of July, there’s a tiny 2ft swell from the west, but it’s a 4-second windswell and the wind is onshore, so it’s just a mess. There’s a brief spike in the afternoon of the 27th of July where the swell hits 5ft from the WNW, and the combined energy jumps to 128 (moderate), but it’s a 5-second period with a fresh cross-shore wind. That’s going to be lumpy, choppy, and pretty much unsurfable.
The water temp is sitting at 58°, which is about 0.9° cooler than normal for this time of year – nothing unusual there.
Into the second week, it’s more of the same. The 6th of August has a 5ft swell from the west in the afternoon, with a combined energy of 196, which is the biggest number we see. But again, it’s a 6-second period with a cross-onshore wind, making it choppy. For a beach break like Aldinga, that’s going to be a messy, closed-out mess. Honestly, given the strong onshore winds expected on the 6th, the setup there looks more interesting for kite surfing than paddle surfing.
The 7th of August shows a cleaner 2ft swell from the SW with a decent 10-second period, but the combined energy is only 67 (weak), and it’s a light cross-shore, so it’s not completely hopeless, but it’s still tiny. The rest of the period fades back into flatness.
So, there you have it. A proper 16-day drought for Aldinga Beach. It’s the sort of stretch where the forecasts might change, but for now, the only thing to do is wait.
Rusty.

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.
