The Lowdown
G'day, Rusty here. Look, I've got to be straight with you – the next 16 days at Aldinga Beach are a real tough watch. We're looking at a long, frustrating stretch of tiny, weak waves and messy conditions. There's no standout period, no real window of quality surf to get excited about. It's a classic case of the waiting game, where you'd be better off giving the board a rest and waiting for the forecast to change.
Starting off Wednesday the 5th, it's a write-off with a piddly 0.7ft swell from the west, weak energy, and just a messy cross-shore breeze. That theme pretty much sticks through the first week. We see a bit of a bump on Sunday the 9th, with the swell jumping to 4ft from the NNW, but it's a short-period windswell (5 seconds) and the wind is a fresh 22 mph cross-shore. The energy is still weak (78), and it's going to be lumpy and ugly. The following days through to the 12th see a bit more size, hitting 6ft from the NW on Tuesday the 11th, but it's blown out by a strong onshore wind, making it a washing machine. The water temp is around 57°, which is about average for this time of year.
The second week is no better. There's a tiny window of glassy conditions on Saturday the 15th morning, but the swell is a pathetic 0.7ft. You might get a clean ankle-snapper, but it's nothing to write home about. The longest period we see is a 15-second groundswell on Sunday the 16th (0.3ft), and again on Wednesday the 19th (0.3ft, 16 seconds), but the size is so small it's irrelevant. For a spot that's already inconsistent and rarely breaks properly, this is a proper dry spell.
Honestly, with the combination of tiny swell, persistent onshore winds, and the shallow, exposed beach setup, this whole period looks more suited to a kite than a paddle. The conditions are just too poor for any kind of decent surf. I wouldn't hold your breath for the next couple of weeks.
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.

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.
