The Lowdown

Alright folks, Rusty here. Gotta be straight with you – this next stretch for Aldinga Beach is a classic case of "wrong kind of weather for the game." Over these 16 days, the ocean’s mostly giving us the cold shoulder for paddle surfing. Let's run through it.

We kick off Thursday the 3rd of September with a bit of a mess. A 4ft swell from the West, but that's a short 5-second period and onshore winds at 16 mph are making a total mess of it. The energy’s weak, only 67, and conditions are flat-out poor. That theme carries through Friday – tiny 1ft swell, still poor.

Saturday morning the 5th looks like a different beast, but not for us on a surfboard. A 7ft West swell rolls in, and the energy jumps to 382 – moderate, pushing strong – but with a 25 mph cross-onshore screaming out of the Waverley Road direction, it’s gonna be a washing machine. For anyone on a kite, this setup’s your ticket. For a paddle surfer? Forget it, it’ll be messy and ugly.

We get a little tease on Sunday morning the 6th. Glassy conditions – I love seeing that word – and a tiny 1ft SW groundswell with a 10-second period. The energy is gutless at 28, so it’s basically a flat, clean pond. Only good for a very patient longboarder or a float.

And that’s pretty much the story for the next week and a half. From Monday the 7th right through to Wednesday the 16th, the chart is full of tiny waves – 0.3ft to 2ft – and while some days have clean offshore or cross-off winds, the swell just isn’t there. The energy readings are all two-digit numbers in the teens or single digits; that’s essentially flat.

Now, a bit further out. On Wednesday the 16th of September afternoon, there’s a small spike – a 4ft Northwest swell with a short 5-second period. It’s coming with a 19 mph cross-onshore and lumpy conditions. The energy is 80 – still weak. Not worth a trip.

And then Thursday the 17th of September morning brings the biggest energy we see – 125 – from a 4ft SW swell, but again it’s short-period (6 seconds) and a 22 mph cross-shore makes it lumpy and poor. Nothing to write home about. Friday the 18th is back to tiny, messy stuff.

So the honest truth, mate? There’s no good surf in this 16-day window for Aldinga Beach. The few days with enough size get blasted by the wind, and when the wind plays nice, there’s no wave to ride. It’s a flat and frustrating run. The water temp on Thursday the 3rd was sitting at about 59°, which is about average for the time of year.

Sometimes the ocean just shuts the door, and this is one of those blank runs. Forecasts change, but right now, leave the boards at home and go for a beach walk.

Rusty.

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.
