The Lowdown
Alright mates, Rusty here. Let’s call a spade a spade: the next couple of weeks are looking as flat as a tack. If you're thinking of paddling out at Aldinga Beach, you might as well leave the board at home. It’s a grim stretch, and I'm not gonna dress it up.
We start off with a bit of bump from a weak, short-period swell, but the wind is all over the place, cross and cross-on, making a mess of everything. The water temp is 57°F, which is about par for the course this time of year. The energy in the water is pathetic, with combined swell energy in the 70s and 90s on Wednesday, but it's not making any waves worth mentioning. Thursday drops right off, and we're left with dribble.
Honestly, from Thursday the 20th through to Monday the 24th, it's tiny. We're talking ankle-biters at best, with the odd 1ft to 3ft bump, but nothing with any punch. The wind stays messy, so it's not even clean. This is a proper dry spell, the kind that tests your patience.
Then, Tuesday the 25th rolls around with a little pulse of energy. The swell jumps to 5ft, with a combined energy reading of 153, which is the most we see in the whole run. But it's a short-period swell at 6 seconds, so it's going to be lumpy and all over the shop. The wind is honking from the south at 12 mph, cross and cross-on, so it will be chopped up. Honestly, it's more of a mess than a wave. The size is there, but the quality is terrible. For anyone on a big board, there might be some push, but I'd call it more of a wind-blown shambles. At 5ft, it's getting a bit much for beginners, but it's not exactly a challenge for the pros either, just ugly.
From Wednesday the 26th onward, it's back to nothing. The swell drops right away, and we see days of 0.3ft to 1ft, with combined energy values dropping into the single digits. The wind does swing offshore at times, especially around the 29th and into September, giving us some clean looks, but there's no swell to clean up. It's all shine and no substance.
Looking into the second week, the 1st and 2nd of September keep that same story: tiny, clean, and absolutely flat. There’s a weak pulse of 2ft on the 3rd from the west, but with a 5-second period, it’s not going to do anything.
So, here’s the bottom line. Aldinga Beach is fickle and doesn't break all that often anyway, and this outlook does it no favors. There are no good surf options in this 16-day window. The conditions are just not on for paddle surfing. With the swell and wind we have lined up, this setup looks far more interesting for the kite surfers than for us. They'll be stoked. But for us, it's a blank run, and that's just how it goes sometimes around here.
The forecasts can change, so keep an eye out, but don’t hold your breath.
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. 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.
