The Lowdown
G’day, Rusty here. Let’s be straight with you. The next couple of weeks are looking pretty bleak for a proper paddle. There’s a long stretch of nothing – we’re talking days of ankle-biters and flat spells. But don’t go swapping your board for a boogie just yet. There’s a small window right at the end that might just get the heart racing again.
Aldinga Beach is the only spot in the mix, and it’s got a long way to go before it’s any good. It’s a beginner-friendly beach break, but it’s inconsistent and pretty exposed. The water’s sitting at 57°F, which is about normal for this time of year.
For the first week, it’s a total write-off. From the 15th through the 22nd, we’re looking at tiny 0.3ft to 0.7ft slop with weak energy (7–16 in the combined reading). The wind is mostly cross-off or light, so it’s clean, but there’s nothing to ride. Saturday the 15th and Sunday the 16th are flat. The swell tries to pick up a touch on the 21st with 3ft from the WSW, but the period is a dribbly 5 seconds and the energy is still weak (49–51). It’s messy, cross-onshore chop. Not worth the drive.
There’s a small bump on the 23rd – 2ft in the morning – but it’s short-period and junky. Then it drops right back off. The 24th is flat again.
Now, here’s where it gets interesting. It’s still a long way out, so treat this with caution, but the 25th of August (Tuesday) has some proper energy showing. The combined swell energy jumps to 195, with a 6ft swell from the northwest. The period is only 6 seconds, so it’s wind swell, but it’s the first real push we’ve seen. The wind is cross-shore from the NNW, which will put a bit of texture on it. Still not great.
The real standout, if you can wait, is Wednesday the 26th of August. The morning is looking at 5ft from the WSW with an energy reading of 143, and the wind is a cross-offshore from the SE – that’s a much better direction for keeping it clean. But the afternoon is where the power arrives. The swell jumps to 8ft from the SW, with the combined energy going nuts at 662. That’s a serious amount of juice. The period is still short (7 seconds), so it’ll be a bit lumpy, and at 8ft, this is only for experienced surfers. It’s going to be big, powerful, and probably pretty shifty on the beach. Not a beginner’s day.
The 27th (Thursday) backs off a touch – 5ft in the morning from the SW, with light offshore east winds, and then the afternoon is glassy with 4ft. That could actually be the cleanest, most user-friendly surf of the whole run, despite the short period. But after that, it’s all downhill again. The 28th and 29th are back to tiny and weak.
To sum it up: don’t bother for the first week and a half. If you’re keen, mark your calendar for the 26th of August for the big one – just be an expert. The 27th looks like a better bet for a more manageable, clean surf. It’s a long way out, so don’t book the day off work just yet, but that’s the best this stretch has to offer.
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.
