The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this outlook for Aldinga Beach is a real struggle. Over the next 16 days, there’s genuinely nothing on offer that’s worth paddling out for. We’re looking at a blank run that stretches all the way from now through to September the 5th. It’s one of those stretches where the ocean just isn’t cooperating.
The Overall Picture
The whole 16-day window is a flat spell. Swell heights barely tickle 0.3 ft to 2 ft at best, and the wave energy is next to nothing – you’re looking at combined energy readings of just 1 to 24, which is weak. The water temp sits around 58°F, which is about average for this time of year, so that’s not the issue. It’s just a total lack of any proper groundswell or consistent wind swell.
First Week (August 21 – August 27)
Through this week, every single session is marked as poor surf conditions. You get a few mornings with clean looking conditions, like Sunday the 23rd with a light cross-offshore breeze from the north at 6 mph, and Monday the 24th has offshore wind from the northeast, but the swell is tiny – we’re talking 0.3 ft to 0.7 ft. There’s just no power. On Tuesday the 25th, a bit of a bump appears in the afternoon with 2 ft from the SSW, but it’s got a short period of 4 seconds and a moderate cross-onshore wind from the SSW at 12 mph making it choppy. Not worth the drive.
Second Week (August 28 – September 5)
The second week is more of the same. There are a few glassy mornings, like Monday the 31st of August with a glassy wind from the NNW at 3 mph, and Tuesday the 1st of September with similar glassy conditions from the SSE, but again, the swell is a pathetic 0.3 ft. By Friday the 4th and Saturday the 5th of September, the wind picks up hard – 19 to 22 mph from the SW and S – and the swell is still 0.3 ft to 0.7 ft. That’s more of a kite setup than a surf one.
The One Standout... Well, There Isn’t One
Honestly, there isn’t a single standout here. Aldinga Beach is an inconsistent beginner-friendly spot, and this forecast leans hard into that reputation. If you’re looking to get wet, bring a bodyboard or a kite, because the paddle-in surf just isn’t happening.
Stay hopeful, forecasts can shift, but for now, leave the board at home.
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.
