The Lowdown
G'day, Rusty here. Let's have a look at what's on the table for Aldinga Beach over the next couple of weeks.
Straight up, it's a quiet stretch ahead. We're looking at a long gap with no real surf to get excited about. The first recommendation doesn't pop up until Monday, the 21st of September, which is a full 13 days from now. Before that, it's just tiny dribbles and poor conditions—nothing worth paddling out for. The water temp is about average for this time of year, so no surprises there.
The one and only standout in this entire run is Monday morning, the 21st of September. There's a bump of swell coming in at 4 ft from the NNW, with a short period of 5 seconds, bringing combined energy of just 67. It's not a classic groundswell by any stretch, but it's the best we've got. The wind is a light northerly at 9 mph, blowing cross-offshore, and that should keep the surface glassy and clean. Aldinga Beach is a fairly exposed spot that needs a solid SW or W swell to really fire, so this NNW direction isn't ideal, but it's offering surfable waves in very ordinary conditions. The break itself is inconsistent and best for beginners, so don't expect a packed lineup—crowds are likely only "often", so you'll have plenty of room to find a few fun, small ones.
After that, the outlook fades again quickly. Tuesday the 22nd and Wednesday the 23rd show tiny, weak swell with onshore or cross-onshore winds, so it's back to flat spells. Given the long stretch of nothing, this is a pretty normal pattern for the area—forecasts can change, so keep an eye on it, but for now, mark that one Monday morning in your diary.
Stay keen.

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.
