The Lowdown
Alright, let’s be honest – the surf scene over the next couple weeks is looking dead flat. We’re not talking about a slow spell, we’re talking about a proper drought. For the first several days, there’s essentially nothing. Tiny 0.5ft dribbles at best, no power, no push. You’ll be floating around with the dolphins and not much else.
From Wednesday right through the weekend, it’s all under 1ft. A few clean, glassy moments – like Thursday morning and Saturday afternoon – but with that kind of size, you’re just bobbing around. No waves to actually ride.
Around Sunday the 20th, we get a slight bump to around 3ft, but it’s short-period and choppy. Nothing special. The following week stays pretty sad. We get a couple of glassy afternoons like Tuesday the 22nd, but still only 0.7ft of swell. That’s not surf, that’s a lake.
The most interesting day might be Monday the 28th. Swell climbs to around 3ft, with combined energy reading 76 to 89 – the strongest we see all window. But the wind is mostly cross-shore and messy, so it’s likely to be lumpy and uninviting. Probably the closest we get to anything rideable, but still not a day to get excited about.
Honestly, there’s no standout in this entire 16-day outlook. No decent swell, no clean period, no proper wind alignment. For beginners, the tiny glassy days might be okay for a bit of practice, but don’t expect to catch anything with actual shape.
So, flat days ahead. If you’re not into long paddles and clean but barely-there waves, you’re better off doing something else. Here’s hoping the next forecast brings something real, ’cause right now there’s not much to work with.
Rusty out.

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.
