The Lowdown
Alright, grab a coffee and listen up. This is a rough one for us. I’ve looked at the charts for Aldinga Beach, and I’ve got to be straight with you: it’s a flat spell. There are no good surf options on the cards for the entire 16-day outlook. Not one.
What we’ve got is a long stretch of small, weak, and messy conditions. The energy just isn't there. For the first week and a half, we’re looking at waves almost exclusively under 0.7ft, often from a westerly direction, which just doesn’t work for us. The swell period is mostly short, so it’s not breaking with any punch. We had a tiny bump on the 15th with 2ft of SSW swell, but it was a cross-shore 15 mph breeze chopping it up, so it was pretty poor. Even the few glassy moments on the morning of the 17th and the 22nd were cursed with barely a ripple – 0.3ft and 0.7ft at best.
We do see a slight nudge around the 20th, with 3ft on the Sunday, but the wind is onshore and choppy. It’s not going to be any good. Later on the 21st, we get a little 1ft from the WSW, but again, it's not enough to get excited about. The only thing that looks like it might have a bit of life is the very tail end of the outlook, around the 26th of September. We see a jump in the long-period energy (a 19-second period) but the height is still only 0.3ft. That’s not surf; that’s a ripple.
So, what does this mean for us? For beginners, this is the perfect time to work on your pop-up in the driveway. It's flat. For the crew, unless you’re jonesing for a long, frustrating paddle on a 0.7ft wave, it’s not worth wetting the suit. The water temp at the start is 59°F which is about average for this time of year, but with no waves, it hardly matters.
This is a blank run. Sometimes the ocean just takes a nap. Given how inconsistent the spot is generally, a few weeks of nothing is more normal than a rare treat. We just have to be patient. Forecasts change, so don’t write it off completely, but right now, there is nothing on offer. I'm going to go wax my board anyway and stare at the horizon. Keep the faith.

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.
