The Lowdown
Alright folks, Rusty here. Gotta be straight with you – it’s a tough watch for Aldinga Beach right now. I’ve scanned the full 16 days, and honestly, there’s nothing on the cards that’s worth paddling out for. The swell energy is just way too weak, and when it does show a pulse, the wind is a mess. Let’s break it down.
We start with a bit of a pulse on Thursday the 3rd, with a 4ft swell from the west and a short period of 5 seconds, but a 15 mph onshore westerly is just going to turn it into a washing machine. The combined energy is only 82, so it’s weak. Then Friday sees a drop to tiny, ankle-knocking 1ft waves. Saturday the 5th is the biggest we’ll see, with a 6ft west swell hitting during strong rain showers and a 25 mph cross-onshore wind. That’s messy, dangerous, and the period is a short 7 seconds, so it’s just a wall of chop. The energy jumps to 326 there, but it’s all wind and no shape.
From Sunday the 6th onward, it’s a long, drawn-out lull. We’re talking days of 1ft and then 0.7ft, and eventually 0.3ft swell. There are a few moments of glassy or clean conditions, like Sunday morning with a 3 mph NW wind, but the swell is just 1ft and 10 seconds – not enough to push a ripple. The energy is down in the single digits or low 20s for most of the second week. The water temperature sits at 59°, which is about average for this time of year.
The long-range stuff from the 14th onward shows a 0.3ft swell with a 15-second period, which is a long period for sure, but it’s just too small. There’s no power behind it, and the energy barely cracks 11. It’s a classic case of a blank run for this stretch. We’ve got an inconsistent, exposed beach break here, and when the forecasts are this flat, it’s not totally unusual. Don’t hold your breath, but keep an eye on the charts – things can change.
Rusty.

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.
