The Lowdown
Alright, Rusty here, and I’ve got to be straight with you – it’s a grim outlook for Aldinga Beach across these 16 days. We’re looking at a real dry spell, with hardly anything worth paddling out for. The surf just isn’t showing up, and we’ve got a long gap of poor conditions stretching from the 13th all the way through to the 26th of September. Most days you’ll be staring at flat, messy, or onshore junk. The odd clean window pops up here and there, but the swell is tiny – we’re talking knee-high at best.
The first real flicker of something surfable doesn’t arrive until the morning of Saturday the 26th. Even then, you’re looking at a weak 4ft swell from the northwest, but with a period of just 4 seconds, that’s all chop and no push. The combined energy is weak (48). It’s clean, with a light cross-offshore breeze, but honestly, it’s not worth rushing for.
A slightly better option shows up the next day, Sunday the 27th of September, in the morning. Swell picks up to 5ft out of the southwest, period is still short at 6 seconds, but the combined energy climbs to a moderate 164. The wind is a clean cross-off from the east-southeast, so it’ll be tidy. For Aldinga, which is fairly exposed to the SW, this is the best we get. It’s not a standout by any means – still short-period and a bit messy – but it’s the only window with a bit of push. The water temp is running about average for this time of year, so no surprises there.
What’s tough is that Aldinga Beach is inconsistent at the best of times, and this stretch proves it. If you’re a beginner, that 5ft on Sunday might be a little too much, so pick your corner. For everyone else, keep your expectations low. This setup looks more interesting for kite surfing than paddle surfing most days. I’ll be watching the charts, but for now, it’s a whole lot of waiting.

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.

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.
