The Lowdown
Alright, it’s Rusty, and I gotta be upfront – the outlook for the next two weeks at Aldinga Beach is a tough pill to swallow. We’re looking at a long stretch of flat or real weak, choppy mess. The whole 16-day window has no surf worth paddling out for. The best I can say is that the poor conditions are pretty consistent with how the area can be, but it’s a real bummer.
Up first, the water temp is sitting at about 58°F, which is pretty much what you’d expect for the middle of winter. Not a big anomaly there.
The first few days, from Wednesday, July 22nd through the end of July, are just small. We’re talking swell heights of 2ft to 3ft, and most of it is windswell with a short period of just 4 to 5 seconds. The energy is weak, with combined energy values barely cracking 22. Winds are mostly cross-onshore or onshore, making it choppy and poor. The afternoon of the 26th and the 28th have some clean moments with light breeze, but the swell is too small to do anything with – 0.7ft – so it’s basically flat.
Then there’s a big gap from the 29th of July all the way through to the 2nd of August. The swell drops to almost nothing, with energy values of 1, and even a few days showing no swell at all. It’s a dead spell.
We finally see a pulse of size on the 3rd of August, with a swell hitting 6ft to 6ft from the WSW. That’s over 5ft, so it’s a bit much for beginners, and the period is only 6 seconds, so it’s a messy, short-period windswell. The combined energy jumps to 211 (moderate energy), but the wind is a strong cross-on or cross-shore, making it lumpy and choppy. It’s not a clean surf day; it looks more like a setup for a kite session than a paddle.
After that, it fades quickly back to small and weak. So, the bottom line is: there’s nothing to recommend here. It’s a blank run, which isn’t abnormal for this spot. Forecasts can change, but right now, I’d hang the board up for a bit.

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.
