The Lowdown
G’day, Rusty here. Look, I’ve gotta be straight with you – this stretch from now through the next 16 days is a bleak one for Aldinga Beach. There’s no surf worth paddling out for. The swell is tiny, the energy is weak, and the conditions just aren’t coming together. We’re talking about a solid run of days where you’d be better off cleaning the wax off your board than chasing waves.
The first real sniff of anything happens on Sunday, September 14th, but even then it’s a short-period, wind-affected mess. The swell is only 3ft from the WNW, with a period of 5 seconds and combined energy of just 43 (weak). The wind is light and cross-off in the morning, so it’s clean, but there’s no push to the waves. A bit of a tease, but nothing to get excited about. By the afternoon, the wind swings to NNW at 16 mph, cross-shore, and lumpy.
The next week is more of the same – tiny swell, poor energy, and onshore winds spoiling what little there is. The water temp is about average for this time of year, so no surprises there.
There is a tiny spike on Saturday, September 19th, when the swell bumps up to 3ft from the WSW, but the period is still a short 5 seconds, and the combined energy is only 58 (still weak). The wind is fresh cross-shore, making it lumpy and choppy. Not a day for a longboard cruiser, and definitely not a day for a beginner – though at 3ft, it’s not too big, just messy.
Honestly, Aldinga Beach is an inconsistent spot, and this blank run is pretty normal for the area. It tends not to stay poor for long, but forecasts can change. For now, the only thing that looks interesting here is the kite surfers – the wind is often strong and cross-shore, but the waves aren’t delivering for us paddle surfers.

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.
