The Lowdown
Alright, let’s get the bad news out of the way first.
Look, I’ve been scanning the charts for Aldinga Beach and, honest to god, it’s a grim 16 days ahead. There’s nothing rideable on offer for pretty much the entire stretch. We’re talking a long, dry spell where the swell just isn’t showing up with any kind of push to get the blood pumping. You’ll be sitting on the sand more than you’ll be paddling.
We start off this Sunday the 23rd with a tiny 0.7ft ripple from the WSW at a short 8 seconds – combined energy is only 11, so weak as a cup of tea... it’s just not surf. Wind is light out of the north so it’s clean, but there’s nothing to ride.
Monday the 24th is even worse – we’re down to 0.3ft from the SW, and while Monday morning has a nice offshore breeze from the ENE, there’s no energy (combined energy of just 3). It’s flat.
Tuesday the 25th sees a tiny spike in height – we get up to 3ft on the Tuesday afternoon, but the period drops to a horrible 5 seconds and the wind is a messy cross-onshore out of the SSW at 15 mph. That’s just choppy, messy junk. Combined energy at 36 – still very weak.
Wednesday the 26th morning has a moment of glassy conditions with the NW wind dead calm at 3 mph, but the swell is only 1.0ft at 6 seconds. You might see a tiny ripple, but don’t paddle out for that.
From there, it’s flat or near flat right through until the end of the month. Even the longer period swells that show up – like the 16-second energy on Friday the 28th – are only 0.3ft. That’s just a long-period bump on the horizon, not a wave you can ride.
The only time we see any real size is way out in the second week. On Monday the 7th of September, the swell jumps to 5ft from the WNW, and combined energy hits 107 (moderate wave energy). But here’s the catch – the period is a short, weak 5 seconds, and the wind is a nasty near gale from the WNW at 34 mph. That is blown-out, messy, dangerous onshore slop. Not surfable.
So, I can’t point you to a stand-out day or break here – there isn’t one. The whole 16-day forecast is pretty much a write-off. For this area, a blank run like this is more normal than you’d hope. Forecasts can change, but right now, leave the board at home.

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.
