The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this outlook for Aldinga Beach is a tough one. We’re looking at a 16-day window that’s pretty much a write-off for any decent wave riding. The consistent theme is "poor surf conditions" across the board, and the numbers back that up.
First up, we’ve got a gap of several days with nothing worth paddling out for. The first real bit of swell energy we see doesn't bring any quality. Expect a long stretch of flat or near-flat conditions.
There’s a small pulse on the morning of Wednesday the 22nd of July, with a swell height of 3 ft coming from the WSW, but the period is a short 4 seconds – that’s windswell junk. The wind is onshore and strong at 16 mph, making it a complete mess. The combined energy is a weak 28 (moderate), so there’s just no power behind it. This is not a surfer’s wave; with that onshore wind and short period, this setup looks more interesting for kite surfing than paddle surfing.
The only notable event in the whole run is on Tuesday the 28th of July, around the afternoon. The swell jumps up to 7 ft out of the NW, with a combined energy of 315 (strong to very strong wave energy). But the period is still a short 6 seconds, and the wind is a cross-onshore at 16 mph. That’s a big, choppy, and blown-out mess. At over 8 ft, that’s expert-only territory anyway, but with the poor wind and short period, it’s not a standout for anyone.
The rest of the window is a mix of tiny waves (0.3 ft to 3 ft), weak energy (mostly under 20), and cross-offshore or onshore winds. There are a couple of glassy moments on the morning of the 26th of July and the morning of the 31st of July, but with swell heights of 0.7 ft and 1 ft respectively, there’s just nothing to ride. The water temperature is about average for the time of year at 58°F (anomaly of -0.9°F), but that won't make up for the lack of surf.
Honestly, there’s no standout. No best on offer. If you’re desperate, the morning of Thursday the 30th of July has a 3 ft SW swell, but with a 5-second period and light cross-shore wind, it’ll be weak and crumbly. It’s not worth the drive.
Keep your board in the car, but the wax on the shelf. Forecasts can change, but this one’s looking bleak.
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.

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.
