The Lowdown
G’day, Rusty here. Look, I’ve had a proper squiz at the charts for Aldinga Beach, and I’m not gonna sugarcoat it – things are looking pretty bleak for the next 16 days. There’s not a single clean, rideable wave on offer for paddle surfing. The forecast shows a long, flat spell with barely a bump, and when the swell does try to show a pulse, the wind or period just kills it. This is one of those stretches where you might as well swap the board for a fishing rod. If you’re dead keen, the only real standout – and I use that term loosely – is a very late call.
Right now, from Friday the 28th of August right through to Wednesday the 9th of September, it’s a desert. Tiny 0.3ft to 1.0ft slop coming from the SW or W, but with periods all over the shop and combined energy readings barely reaching double digits (like 15 or 5). Sure, Friday the 28th has glassy conditions in the morning and clean cross-off winds pop up here and there, but with 0.3ft swell and a 16-second period, there’s just no water moving. It’s flat. As we get into the first week of September, the wind cranks up – we’re talking strong N winds at 30 km/h, then raw W and NW onshores at 25 km/h, turning the water into a messy, lumpy chop. The swell only nudges up to 2ft to 3ft, but with periods of 4 to 5 seconds and onshore wind, it’s just blown-out whitewash. A kite surfer might get a thrill out of the 5ft cross-shore chop on Friday the 4th (combined energy 169), but for a paddle surfer, it’s a write-off.
Then there’s a real flicker of hope on Thursday the 10th of September. The morning shows a clean 5ft W swell with a 6-second period and a combined energy of 154. The wind is super light from the NNW, making for a light cross-shore. That’s the best-looking window, but it’s still a short-period wind swell, so don’t expect any grunt or shape. In the afternoon, the swell jumps to 10ft with a massive combined energy of 859, but the period is still only 7 seconds and the wind swings onshore from the S. That kind of size and energy with a short period and onshore wind isn’t surfable for most. It’s a boat wake, not a wave. That morning is your only real look. It’s over a week away, so keep an eye on it, but don’t hold your breath.
For the rest of the outlook into the 11th and 12th of September, it’s back to small, weak, or messy conditions. The water’s about average temperature for the time of year, but you won’t be getting in the water enough to notice.
Bottom line: there’s nothing good on offer for paddle surfing at Aldinga Beach in this 16-day window. It’s a tough stretch. But stay hopeful – these flat spells don’t last forever, and forecasts can change.
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.
