The Lowdown
Alright folks, it’s Rusty here, and I’ve had a good look at the charts for the Aldinga Beach region. I gotta be straight with you – this upcoming stretch is a tough one for paddlers. We’re looking at a long, lean period with very little on offer.
The pattern overall is pretty bleak. The first week is essentially a write-off, with very small, weak, and often choppy conditions. From the 20th of July right through to the 26th, we’re dealing with tiny waves under 3 ft, short periods, and mostly onshore or cross-onshore winds that just mess it up. The combined wave energy is barely a whisper, often in the single digits. It’s not a time to get excited.
There is a brief, flickering moment on the 27th of July. Monday morning brings a pulse of 6 ft swell from the NNW, which is not the ideal SW direction for this spot, but the wind goes glassy – that's a major positive. The combined energy jumps to 141 (moderate), so there’s some push. But the period is a short 5 seconds, so it’s gonna be weak and crumbly. It’s surfable, but very ordinary. The afternoon sees the wind shift, turning it messy again.
After that, it’s back to the doldrums. From the 28th of July through the 4th of August, we’re looking at a mix of windy, choppy conditions and, eventually, absolute flatness. The last few days of the forecast show zero swell, with the combined energy hitting 0. That’s a flat spell to end the forecast period.
So, what’s the best? There is no standout. The only half-decent moment is that Monday morning (27th of July) with the 6 ft swell and glassy conditions. But with a 5-second period, it’s going to be a bit of a disappointment. For beginners, that 6 ft is getting a bit big, but the short period might make it manageable. The rest of the period is a total no-go. Hang up the wettie for a bit, or check the forecasts again in a few days.
Rusty.

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.
