The Lowdown
Alright, Rusty here. Let's be straight with you. This is a rough stretch for Aldinga Beach, and I'm not going to sugarcoat it. The swell is weak, the periods are short, and the wind is mostly useless. We're looking at a solid run of poor conditions with barely a glimmer of hope.
Water temp is sitting at 57°, which is pretty much spot on for this time of year, nothing unusual there.
The first week is a total write-off. From Wednesday the 19th right through to Friday the 28th, it's a wasteland. The swell is tiny, mostly under 3ft, with short periods around 4 to 7 seconds, and the combined swell energy is pathetic, barely cracking 94. The wind is mostly cross or cross-onshore, adding chop to already flat waves. You'll be chasing your tail out there.
Now, we start to see a little pulse of life around the end of the month. Friday the 28th afternoon, we get a hint of something. The swell is still small at 4ft from the SW, but the period is a weak 5 seconds. The energy is still low at 77. The big news is the wind goes glassy, which is a massive positive. You'll have clean, crumbly waves, but they're very ordinary. It's a 1 out of 10, so it's barely surfable, but it's the best we've seen.
Saturday the 29th morning is another contender. The swell is 4ft from the SSW with a 5 second period, and the wind is a clean offshore from the ENE at 12 mph. The combined energy is 75. Again, it's surfable but very ordinary. The break is often crowded, so you might have some company out there, but the clean offshore wind is a major positive.
After that, it drops off a cliff again. From Sunday the 30th all the way through to Thursday the 3rd of September, the swell collapses to tiny 0.3ft to 1ft waves with laughable energy. It's a total bust.
So, here's the deal. The standout window is Friday the 28th afternoon and Saturday the 29th morning. The swell is small, but the wind is perfect. On Friday afternoon, you get glassy conditions with 4ft swell from the SW. On Saturday morning, you get clean offshore wind with 4ft swell from the SSW. The break is inconsistent, so you'll be waiting for sets, but when they come, they'll be clean. The best bet is to paddle out on Saturday morning for the cleanest, most workable conditions.
This is a survival mission, not a classic session. Keep your expectations low, and you might just scratch an itch.
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.
