The Lowdown
Alright, let’s get into it. This is a grim outlook, I’ll be straight with you. Aldinga Beach is a beginner-friendly, inconsistent spot that’s fairly exposed to the swell, and it’s usually best with a good SW groundswell. But over the next 16 days, there’s just nothing to get excited about.
The water temperature is sitting at 58°F and that’s pretty much spot on for this time of year, so no surprises there.
We kick off Tuesday afternoon, August 25th, with a weak 4 ft SW swell, but the wind is a fresh cross-on at 19 mph, and the wave energy is just a measly 78. The rip is small and the period is short, so conditions are going to be lumpy and poor. Honestly, not worth paddling out.
Then we hit a massive dry spell. From Wednesday, August 26th, right through to the end of the forecast window on September 9th, the swell barely flickers. Wave heights hover around 0.3 ft to 0.7 ft, and the swell energy sits in the single digits or low teens. The wind does get glassy and clean on a few mornings, like the 26th and 28th, but with zero swell, it’s a flat lake. You’d be better off going for a swim.
There’s a tiny pulse on September 1st, with a 3 ft NW swell, energy of 39, and a period of just 5 seconds, but the wind is all over the place and the quality is still poor. Later, on September 9th, there’s another weak 3 ft WSW swell, but again, period is a ridiculously short 4 seconds, so it’s just wind slop.
The bottom line: there’s no surf worth chasing here in the 16-day window. This area is going through a flat spell, and it’s not unusual for this stretch. Forecasts can change, but right now, I wouldn’t even bother waxing the board.

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.
