The Lowdown
G’day, it’s Rusty.
Well, I’ve had a good look at the charts for Aldinga Beach, and I’ve got to be straight with you – it’s a lean stretch. We’ve got a 16-day window stretching from the 14th of August through to the 29th, but honestly, there’s nothing that’s going to get the heart rate up. We’re looking at a serious flat spell for the first week, and even when the ocean does wake up a bit in the second week, it’s pretty marginal.
Right out of the gate, from Friday the 14th, it’s tiny. We’re talking knee-high slop at best, with a swell height of just 1 ft to 1 ft. The energy is pretty much non-existent, with readings down in the single digits, like 13 on Friday afternoon. The wind is mostly cross-off or offshore, which is nice and clean, but there’s just nothing to push you along. This flatness carries right through until about the 20th. So, if you’re wanting a surf, you’re looking at about a week of no good options. It’s a dead run.
Around the 21st and 22nd, things get a little interesting, but only for the wrong reasons. The swell bumps up slightly to 3 ft, but the period drops right off to 4 or 5 seconds. That’s pure windswell, all chop and no push. The energy climbs into the 40s on the 21st, but with that short period, it’s just messy. It’s not going to break with any sort of shape. By Sunday the 23rd, there’s a bit of a pulse with the swell pushing 5 ft on the Sunday afternoon, and the energy jumps to a moderate 106. But again, the period is a lousy 5 seconds. It’s just going to be a crumbly mess, and the wind swings onshore, so it’ll be lumpy too. This isn’t a day for a board; it’s more of a day to watch the whitecaps and think about other things.
The rest of the run into the end of the month stays poor. We get some bigger wind on the 26th – a strong breeze hitting 28 mph – but the surf stays small and jumbled. There’s a moment on the 28th where it goes glassy early with a light offshore, and we have a bit of 2 ft swell, but the period is still down around 4 seconds. It’s clean, but there’s just no power behind it. It’s the kind of day you’d go for a paddle, not for a proper surf.
So, the verdict is this: for the next two-plus weeks, Aldinga Beach has nothing to offer. It’s ironic, because the water temp is a touch cool at 57°F, but that’s about average for this time of year. The only real excitement out there might be for the kitesurfers, especially on a day like the 26th when the wind is howling but the surf is junky. For us surfers, it’s a waiting game. A blank run like this can happen, but the ocean always comes back around. Keep the boards waxed, keep an eye on the charts, and we’ll get some proper lines soon enough.
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.
