The Lowdown
Alright, Rusty here again, but this time in feet and miles. Let’s get into it for Aldinga Beach. I’m looking at the next couple of weeks, and honestly, it’s a tough one. We’ve got a massive stretch of nothing coming our way.
The first real chance to get wet isn’t until Saturday, September 5th – that’s nearly two weeks from now. The whole run before that is tiny, with swell heights barely hitting 0.3ft to 0.7ft and combined wave energy living in the single digits (3 to 17). It’s a flat spell, plain and simple. The wind is often clean, but you can’t surf clean flat water.
On Saturday morning, September 5th, we finally see a pulse. The swell bumps up to about 4ft from the NNW, with a combined energy of 102 – that’s moderate. The problem is the period is a short 5 seconds, so it won’t have any punch. It’s a messy windswell. The wind is light and cross-offshore from the ESE, so it’ll be clean on the surface. It’s a "meh" option – you might get a few soft, lumpy rides, but it’s really only for beginners. The water temp is sitting right around average for the time of year.
That little pulse dies fast. Sunday morning, September 6th, has 3ft from the W and a glassy morning, but the energy is already dropping (45). By the afternoon, the wind turns onshore and ruins it. Monday, September 7th is a write-off with onshore gales and rain.
So, no standouts here. Nothing to get excited about. The only day worth a mention is over a week away, and it’s a weak, short-period swell. This is a long, quiet patch for Aldinga. Forecasts can change, but right now, it’s a waiting game.
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.
