The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Aldinga Beach over the next couple of weeks.
Straight up, I’m not gonna sugarcoat it – this is a grim stretch for Aldinga Beach. The forecast is basically a 16-day flat spell with garbage conditions. For the first week and a half, from now through to the end of July, there’s nothing to get excited about. Swell is tiny, mostly under 1 ft, with weak, short-period wind slop that’s just not worth paddling out for. The combined energy is laughably low (mostly single-digit values), and the wind is almost always onshore or cross-onshore, keeping the surface chopped and messy. It’s a proper write-off.
The only faint glimmer of hope arrives on the morning of Saturday, 1 August. There’s a bump to 5 ft out of the west, which is the biggest swell of the whole period. The combined energy hits 109 (moderate), and with a clean, cross-off breeze from the north at 18 mph, the surface could be tidy. But honestly, the swell period is only 5 seconds – that’s just wind-chop, not a proper groundswell. It’ll be weak, crumbly, and won’t hold any real shape. For a beginner spot that’s inconsistent at the best of times, it’s still a no-go for most. The afternoon sees the wind swing cross-shore and the swell drop off.
There’s a run of clean, offshore mornings in the last few days of July, but the swell is pitifully small, so it’s board shorts and a tan, not a surf.
Overall, this is a solid blank run. Aldinga Beach is an inconsistent break, and when it’s like this, there’s just nothing to chase. Keep an eye on the charts, but honestly, forecasts can change, and it tends not to stay this poor forever. But for now, it’s a no.
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.
