The Lowdown
Alright, let’s be straight with you. No point sugar-coating it – if you’re looking for surf at Aldinga Beach over the next couple weeks, you’re gonna be looking hard. The whole 16-day run is a write-off. We’ve got a solid gap of nothing ridable starting now, and it just doesn’t let up.
Kicking off Saturday the 15th, we’re looking at tiny 0.2m waves from the west with a short 7-second period. The combined swell energy is only 7, which is about as weak as it gets. There’s a cross-offshore breeze but there’s just no power to work with. That sets the tone. Sunday the 16th through to the end of the first week, it’s even smaller – 0.1m dribble – and while we get a brief window of offshore winds from the ENE on Monday the 17th, the swell is still a pathetic 0.1m with a 13-second period that’s just not pushing any water.
Mid-week gets messy. By Wednesday the 19th, the wind swings onshore and we get rain, making it a total lumpy, choppy mess. Thursday the 20th is light cross-onshore with swell barely breaking 0.2m. Then around Friday the 21st and Saturday the 22nd, we finally see some size – 3ft to 5ft from the west – but the period is a hopeless 4 to 6 seconds. The swell energy jumps to 126 and 140 on those days, which is moderate, but the wind is howling cross-on or onshore at 18 to 25 mph. That’s not surfing, that’s a washing machine. It’s more interesting for kite surfing than paddle surfing.
The second week stays poor. Sunday the 23rd through to the end of the month, we’re back to tiny waves and poor conditions. There’s a moment on Tuesday the 25th with clear skies and light offshore winds from the ENE, but the swell is only 2ft from the southwest with a 5-second period – just not enough grunt.
The water temp at the start is 57°, which is about normal for this time of year – no anomaly worth mentioning.
Bottom line: there’s no standout, no best day, nothing to get excited about. This kind of blank run happens here. Like I said, sometimes the ocean just says “not today.”

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.
