The Lowdown
Alright, grab a coffee, let’s talk surf. I’m Rusty, and I’ve been looking at the charts for this stretch of coast, and it’s a flat, quiet start that’s going to test your patience.
We’re looking at a real dry spell for the first week or so. The swell is tiny, barely a ripple, with heights under 1 foot. The wind is all over the place – cross-shore, onshore, glassy in the wrong spots. The combined wave energy is weak, with numbers like 31 or even down to 1. It’s a period where you’re not missing anything.
The first real sign of life comes on Sunday, September 20th. The swell bumps up to 6 feet out of the west, but it’s a short period of 7 seconds. The combined energy gets to 371, which is moderate, but it’s a wind swell, so it’s going to be a bit lumpy. The wind is moderate cross-onshore from the west, so the surface is choppy.
Aldinga Beach is the only spot in the forecast. That 6-foot west swell with a short period is going to be messy. The wind is not helping. For beginners, this is too big and too rough. With that cross-onshore breeze and short period, this setup is more interesting for kite surfing than paddle surfing.
The one bright spot is on Monday, September 21st, in the morning. The swell is still 6 feet out of the west, but the wind turns a light offshore from the north. The combined energy is still solid at 247. The wave comment says “surfable waves but very ordinary conditions,” but that clean offshore wind on a 6-foot wave is the best we’re going to see in this whole 16-day stretch. The period is still short at 6 seconds, so it’ll be a bit gutless, but it’s the standout.
After that, it’s back to small, weak, and windy. The long-range outlook is too uncertain.
So, if you’re itching to paddle out, the Monday morning session on the 21st is your only real chance for a clean wave with some size. The rest of the time, it’s a waiting game.
Rusty.

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.
