The Lowdown
Hey, Rusty here. Gotta be real with you – the outlook for Aldinga Beach for the next 16 days is a total bust. There’s a big gap of nearly a week with nothing at all worth getting wet for.
We start on Saturday, August 29th, but it's barely a breath. Swell is a pathetic 0.3ft from the SW, with a 10-second period and a combined energy of just 4 (weak). Wind is light and cross-off from the E, so the water is clean, but there’s nothing to ride. This same tiny, clean-but-powerless scenario drags on all the way through September 6th. Sunday afternoon, August 31st, goes glassy, but on a 0.3ft wave it’s flat.
Then on Monday, September 7th, we get a spike – the swell hits 6ft from the S. The period is short at 6 seconds, and the combined energy jumps to 216 (moderate). But here’s the kicker: the wind is a cross-onshore from the SSW at 9 mph, making everything lumpy and choppy. This is looking way better for a kite session than a clean surf at this beach. That swell drops off fast, and by the 8th it’s back to nothing.
We see one more blip on September 12th – a 0.3ft swell with a very long 17-second period (15 energy). But without any size, that long period just means beautiful lines that won't break properly at the beach. The rest is more of the same: tiny and onshore slop.
There is zero standouts in this 16-day window. The only pulse of real energy on the 7th is totally blown out. It’s a dry spell, and it happens around here.
The water temp is about average for the season, so you'll be fine in a spring suit if you just want to soak.
Stick the board in the rack and wait for the next proper swell.
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.
