The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the menu for Aldinga Beach over the next couple of weeks.
First off, I gotta be straight with you – it’s a long, flat spell to start. We’re talking day after day of tiny, weak dribble. The swell energy is in the single digits most of the time, and what little is there is short-period and messy. The wind is all over the place, but the waves just aren’t there. It’s a tough stretch for anyone wanting to paddle out. For a spot that’s already inconsistent, this kind of blank run is not unusual, but it still stings.
Now, water temp is sitting at 57.7° with a slight negative anomaly of -0.9°, so pretty much what you’d expect for this time of year – no shocks there.
The only real light at the end of the tunnel is Saturday the 8th of August. That morning, we’re looking at a solid 9.8ft swell from the WSW, with a combined energy reading of 1332 – that’s some serious grunt. The wind is a clean cross-off from the north at 9 mph, so the surf should be firing and looking pretty clean. That’s a lot of water moving, though – over 8.2ft, so this is strictly for the experienced crew. Beginners, sit this one out. The afternoon settles a bit to 7.2ft from the west, still with clean cross-off wind, but the energy drops to 447. Still good, but the morning is the standout.
The following Tuesday, the 11th of August, sees another big pulse of 9.8ft from the WSW, but the wind is howling straight onshore from the same direction at 19 mph. That’s going to be a washing machine – blown out, messy, and not worth the paddle. The energy is high (880), but the quality is poor. That’s more of a kite day than a surf day.
After that, it fades back into small, onshore junk for the rest of the outlook. The 12th has a little bump at 3.6ft, but it’s cross-onshore and choppy, and the 13th is just howling gales with tiny waves.
So, bottom line: if you’re an experienced surfer, circle Saturday the 8th of August in the morning. That’s your window. Everything else is a write-off. Don’t hold your breath for the rest.

A general guide to surfing at Aldinga Beach can be found by selecting the local surf guide option on the grey menu.

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.
