The Lowdown
G’day, Rusty here. Gotta be straight with you—this is a tough run for Aldinga Beach. The entire 16-day outlook is a blank, mate. No decent surf to get excited about. It’s not uncommon for this stretch to go quiet, but it doesn’t mean it’ll stay this way forever; forecasts can shift. Let’s walk through what’s happening.
Right from the start, Sunday the 30th of August, it’s flat. Tiny 0.3ft swell with a long 12-second period but barely any energy (5). Cross-off wind early, then cross by afternoon. Clean conditions, but you’d be dragging your knuckles on the sand.
Monday the 31st sees a 0.3ft W swell, glassy in the afternoon—dead flat but pretty. Still nothing to ride.
Tuesday the 1st of September picks up a bit of wind—strong northerly at 19 mph in the morning. Swell bumps to 3ft from the NNW by afternoon but with a short 5-second period and weak energy (54). Poor quality.
Wednesday the 2nd through to Thursday the 3rd brings onshore winds and choppy, messy surf. Swell stays under 3ft for the most part, with energy barely reaching 46. No good.
Friday the 4th and Saturday the 5th see a pulse—Saturday morning has 6ft swell from the WSW with a short 6-second period and moderate energy (265). But onshore winds at 28 mph make it a kite surfer’s dream, not a paddle surfer’s.
Sunday the 6th of September: 8ft swell from the W, strong energy (636), but cross-onshore winds and lumpy conditions. Too big for beginners, and the shape will be blown out.
Monday the 7th peaks at 10ft from the WSW, 8-second period, very strong energy (1181). This is big, heavy, and onshore—experts only, and even then it’ll be a washing machine. Stay safe.
The rest of the week into the 14th of September drops off fast. Swell shrinks back to 0.7-2ft with weak energy. A few glassy moments on the 13th and 14th with 2ft and 0.7ft swell, but still nothing to surf.
Water temp is about average for this time of year, no big anomaly. No standout breaks, no recommendations. Hang the board up for a fortnight and keep an eye on the charts, mate.
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.
