The Lowdown
G’day, Rusty here. Look, I’ve been staring at the charts for Aldinga Beach, and I gotta be straight with you—there’s nothing worth paddling out for in this entire 16-day stretch. Not a single session that’s gonna get the heart pumping. It’s a tough run, but it happens.
Right now, Sunday the 23rd of August, we’ve got a tiny 0.7ft swell from the WSW at a short 8 seconds. The combined energy is a weak 7. Wind is a bit onshore, but honestly, it doesn’t matter—the surf is just poor. There’s no real energy to work with.
The whole week is a write-off. Monday and Tuesday stay flat and weak, with the swell barely hitting 0.3ft to 3ft. Tuesday the 25th gets a bit of a bump from the SW, but the wind is a messy cross-onshore at 15 mph, and the period is a shocking 4 seconds. The combined energy only reaches 33—that’s tiny. It’s choppy and terrible.
Wednesday through to Saturday the 30th of August is more of the same: tiny waves, short periods, and mostly cross or onshore winds. There’s a brief moment on Sunday the 30th with glassy conditions in the morning, but the swell is still just 0.3ft. You could sit out there and float, but you won’t be surfing.
Heading into the second week, it doesn’t get any better. From Monday the 31st of August through to Monday the 7th of September, the swell occasionally lifts to 3ft on the 3rd of September, but the period is 5 seconds, the wind is onshore, and the combined energy is a weak 49. It’s just messy and unsurfable.
The only break on offer here is Aldinga Beach (South Australia). It’s an inconsistent beach break, and it’s rarely firing. The water temp is about 58°, which is pretty normal for this time of year—nothing unusual there.
Overall, this is a blank run. For this area, it’s not unusual to have long gaps with no surf. The forecasts can change, so keep an eye out, but for now, don’t bother loading the boards.
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.
