The Lowdown
Right, let’s have a look at what’s cookin’ for Aldinga Beach. I’ll be straight with you – the next 16 days are a tough stretch for anyone lookin’ to get a proper wave. We’ve got a whole lot of flat spells and blown-out mess, but there’s a tiny glimmer if you’re patient.
The first bit of the run is all about tiny, weak surf. Friday 31st July is a write-off with a 0.7ft swell from the west, a period of only 7 seconds, and combined energy of just 4 – that’s practically nothin’. The water’s sittin’ at 57°, which is about average for this time of year, so no surprises there. At least Saturday morning the 1st of August has a light breeze, but with a 0.3ft swell, it’s more of a paddle than a surf.
We get a bit of a bump on Sunday 2nd August afternoon when a 3ft west swell shows up, but it’s got a short 5-second period and a fresh cross-onshore wind from the WNW at 22 mph. That’s gonna be lumpy and messy – more for the kite crew than a surfer. The combined energy only hits 54, which is weak.
The long-range has a bit of a thump on Monday 10th August morning. The swell jumps to 7ft from the west with a period of 7 seconds, and the combined energy rockets up to 440 – that’s moderate to strong energy. But the wind is a strong cross-shore from the NNW at 28 mph, makin’ it a messy, choppy affair. That’s a big, bumpy, expert-only day if you’re desperate, but honestly, it’s blown out. The afternoon is even worse with a near gale.
Overall, there’s no standout session here. The waves are too small, too short-period, or hammered by wind. Aldinga Beach is an inconsistent spot at the best of times, and this run is a real test of patience. The forecast can always change, but right now, you’re better off savin’ the petrol.

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.
