The Lowdown
Alright, mate, Rusty here. Let’s be straight with you. Looking at the next couple of weeks, it’s a pretty quiet stretch for Aldinga Beach. We’ve got a long, flat spell ahead, so don’t get your hopes up for any fireworks just yet. The first week is basically a write-off, and we’re looking at a gap of nearly a week before anything even gets close to rideable.
The first real chance of anything comes on Monday the 10th. We’re seeing a pulse of swell push in around 5ft from the southwest, but the wind is going to be howling onshore and choppy. The energy is moderate at best (138). It’s not going to be pretty – it’s more of a messy, blown-out affair than a clean surf. The period is short, around 6 seconds, so it won’t have much push behind it. This is definitely a case of better to stay on the beach than paddle out into that.
The rest of that first week is more of the same – small, weak, and messy. The swell drops right back down, and the winds stay mostly cross or onshore. There’s a moment on Friday morning the 14th where the wind goes glassy and the surf is a tiny 1ft, but that’s not going to get anyone too excited. It’s clean, but there’s nothing to ride.
The long gap continues right through to the end of the forecast period. We finally see a bit of life around Monday the 24th, with a small pulse of southwest swell at 2ft in the morning, bumping up to 4ft by the afternoon. The wind is light and cross-shore, which is better than what we've seen. The energy is still on the weak side (24 and 59), and the period is short, so it’ll be a bit lumpy, but it’s the only time we might see a few rideable, if not perfect, waves. It’s not a standout by any stretch, but it’s the best on offer.
Other than that, there are a few days with tiny 0.3ft leftovers and clean conditions, but those are ankle-biters. The pick of the entire run is probably that Monday afternoon, but even then, we’re talking about a small, short-period swell. It’s a quiet couple of weeks, folks. Keep the board in the car, but don't be surprised if you don't get wet.
Rusty.

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.
