The Lowdown
G’day, Rusty here. Look, I’ve had a good look at the charts for Aldinga Beach, and I’ve got to be straight with you – it’s a tough stretch ahead. There’s nothing in the first week that gets my heart rate up, and the whole 16-day window is a long, flat slog with barely a ripple worth paddling for. The first surf recommendation doesn’t even show up until Sunday the 20th, and even then it’s a bit of a letdown. We’re looking at a big gap of no real surf from now until that Sunday.
Aldinga Beach is a pretty exposed spot, and it’s usually got some life, but this run is stubborn. The combined swell energy is weak – down around 1 to 29 for most of the first week, which is barely a bump. On Tuesday morning the 15th, we’ve got a 3ft SW swell, but it’s a short-period 5 seconds, cross-on wind from the south at 16 mph, and the whole thing is chopped out. Poor. The wind stays messy through the week, with cross-shore and cross-off breezes, but the swell is tiny – 0.7ft, 0.3ft – and the energy is in the single digits. By Thursday the 17th, there’s a glassy morning with 0.3ft and a 9-second period, but that’s barely a ripple. Clean, yes, but there’s nothing to ride.
We finally see a pulse on Sunday the 20th. The morning brings a 4ft W swell with a short 6-second period, combined energy of 94 – still weak, but the biggest in the run. The catch is the wind: cross-on from the WNW at 16 mph, making it choppy. It’s not great, and that swell is too short and wind-affected to be fun. After that, it fizzles again. Monday the 21st has a glassy morning with 1.0ft WSW swell, 10-second period, energy of 23 – clean but tiny. You could maybe catch a knee-high runner if you’re desperate, but it’s not worth the drive.
The second week doesn’t offer much more. We get a few clean, glassy windows – like Tuesday the 22nd afternoon with 0.7ft and glassy conditions, and Saturday the 26th morning with 1.0ft and glassy again – but the swell is so small it’s barely a wave. The energy stays low, in the 1 to 42 range. By Sunday the 27th, the wind picks up to a strong 28 mph cross-on from the south, with moderate rain, and it’s messy. That’s not surfable.
There are no standouts here. Aldinga Beach is inconsistent at the best of times, and this forecast is a flat spell. If you’re after a paddle, you might find a tiny clean wave on Monday the 21st or Saturday the 26th, but honestly, the kite surfers might be the only ones having fun when that 4ft W swell hits on Sunday the 20th with the cross-on wind. The water temp is about average for this time of year, so no surprises there.
Keep an eye on the forecasts – it tends not to stay this flat for long around here. But for now, I’d hang the wettie up.
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.
