The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
Straight off the bat, I gotta be honest with you – it's looking pretty grim. There's a real long stretch of flat, small, and messy conditions ahead. We're talking a solid two-week gap with barely a ripple worth paddling for. The only break on the cards is Aldinga Beach, and it's inconsistent at the best of times, so this kind of blank run isn't totally out of the ordinary for the area.
The first real sniff of anything that might get your heart rate up doesn't come until Sunday, the 20th of September. We finally see a pulse of swell roll in, with a moderate 5.6 ft of mixed-up, short-period energy (6 seconds) from the WSW. The combined energy hits 232 (moderate energy), so there's a bit of grunt in the water. But – and it's a big but – the wind is a cross-shore, messing up the surface. It's not going to be pretty, but it's the only show in town.
Even then, the next day, Monday the 21st, sees the swell drop back to a weak 3.3 ft, and the wind swings cross-onshore. For a beach break like Aldinga with that sloppy wind and short period, honestly, this setup looks more interesting for a kite surfer than a dedicated paddle surfer.
So, there you have it. A long wait for a very average, short window. Fingers crossed the forecasts change, because right now, it's a tough watch.

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.
