The Lowdown
Alright, folks, Rusty here. Let me level with you. The next couple of weeks are looking pretty grim for a proper paddle. We’ve got a long stretch of flat, weak conditions ahead, so don’t be surprised if the board stays in the car.
The first real surf window we’re looking at doesn't show up until Sunday, September 7th, and even that’s a bit of a tease. Before that, we’re looking at a solid week and a half of nothing but dribble. There are a few tiny pulses here and there, but nothing that will get your heart racing.
However, there is a glimmer of hope on that horizon. That swell on the 7th is the only thing worth talking about. The energy jumps to 294 in the water (moderate wave energy), with a 7ft swell rolling in from the W. The period is short at 6 seconds, so it’ll be a bit crumbly. The wind, though, is gonna be a problem. A moderate cross-onshore from the NW is going to chop it up something fierce. This is looking more like a day for the kite surfers out at Aldinga Beach than for us paddle surfers. With the onshore wind and lumpy conditions, it’s going to be messy.
Now, if you’re desperate, there might be a tiny window on August 25th. Swell ticks up to 3ft from the SW, but the period is a woeful 5 seconds, and the SSW cross-onshore wind will make it choppy. It’s not worth the drive unless you're just keen to get wet.
The wait is long, and this blank run is pretty normal for this spot. The occasional wind swell and lack of any strong groundswell means we just have to be patient. Don't write the whole two weeks off, though. Forecasts can change, and there's always a chance something shifts. But right now, it's looking like a lot of glassy, flat mornings and a few blown-out afternoons.
For now, I’d say hang tight, check the cams, and be ready to move if that forecast for the 7th cleans up. Until then, I’m just keeping the wax warm.

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.
