The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the menu for Aldinga Beach for the next sixteen days. I’ll level with you straight up: this is a grim run. The forecast is basically a long, flat stretch of tiny, junk surf with nasty winds, and it’s going to be a tough wait for anything that even looks like a wave.
The whole period kicks off with a whole lot of nothing. From Friday the 4th of September right through to the middle of the month, it’s practically a desert. We’re looking at the smallest of small swells, mostly below 1 ft, with a few days of strong onshore wind that’ll just chop up whatever’s there. The combined wave energy barely cracks double digits for most of that time; it’s weak and lifeless. There’s a real gap of about two weeks where I wouldn’t even bother paddling out.
The only real glimmer of hope is on Friday the 18th of September afternoon. That’s when we see a jump to a 10 ft swell from the WSW, with a short period of 8 seconds. The energy is massive, hitting 1318, but it’s a messy, powerful close-out for a beach break. The wind is light onshore, so it’ll be lumpy. This is strictly for the experts. Beginners, stay well clear—this is way too big. The wave comment says "marginal surf forecast," so it’s not a total write-off, but it’s a freight train, not a playful wave.
So, the honest truth: there’s no standout. If you’re an experienced surfer looking for a serious challenge, keep an eye on that Friday the 18th, but don’t expect perfection. For everyone else, it’s a flat spell. The water temperature is about 58°F, which is totally normal for this time of year, so no surprises there.
Stay patient, and check back in a few days. Forecasts can change.
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.
