The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer at Aldinga Beach over the next couple of weeks.
Straight up, I’m not gonna sugar-coat it – this is a tough run. The forecast is looking pretty bleak for any kind of decent paddle session. We’ve got a solid 16-day window, but the surf is just not cooperating. The first real chance to even think about getting wet is a long way off, so if you’re hanging for a wave, you’re gonna have to be patient.
For the first week and a half, it’s a write-off. From Monday 10 August right through to the middle of the following week, the swell is tiny, the wind is messy, and the energy is just not there. The water temp is sitting at 57°, which is about average for this time of year, so at least it’s not a shock to the system.
We finally see a tiny pulse of energy on Wednesday 19 August morning, but it’s only 0.3 ft with a period around 10 seconds – that’s barely a ripple. The combined swell energy is a paltry 2 (two), so you’d be better off finding a rockpool.
The only faint glimmer of hope comes right at the end of the run. On Tuesday 25 August afternoon, we get a clean offshore wind from the NNW at 12 mph, and a tiny 0.3 ft swell from the SW with a very long period of 15 seconds. The combined energy is still only 18 (eighteen), so it’s weak. This is a long-period groundswell, which at Aldinga Beach – a fairly exposed beach break – might just break too straight to offer much. It’s a long shot, but it’s the cleanest conditions we see.
If you’re a kite surfer, the windier days with some chop might be more interesting than anything on offer for a paddle. But for a surf? This is a blank run plain and simple. The area just doesn’t have the juice right now. Forecasts can change, but for now, I’d leave the board in the garage.
Rusty.

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. If you surf the same spot (Aldinga Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
