The Lowdown
G’day, I’m Rusty.
Let’s be honest – Aldinga Beach is a total no-go for the next 16 days. There’s not a single session worth your time. The whole outlook is a bust.
Right from Monday 17 August through Monday 24 August, the swell is tiny – 0.3 ft to 1 ft, with a couple of 4 ft to 4 ft bumps on Wednesday 19 and Thursday 20 August, but those are just short-period windswell at 5 seconds. The combined energy is weak, ranging from 2 to 64. Winds are cross-on, onshore, or just ugly, leaving the water choppy and lumpy. Even the glassy Sunday 23 August afternoon with 0.7 ft and 8 seconds won’t give you a thing – it’s flat.
The second week picks up a little on Thursday 27 August, with a 8 ft swell from the WSW at 7 seconds – that’s moderate energy at 637. But the wind is cross-on at 15-19 mph, so it’s lumpy and messy. That’s only for the experts, and even then, the quality is poor. After that, it’s back to tiny surf and light winds, but nothing rideable.
Water temperature sits at 14°, about average for this time of year.
If you’re into kite surfing, that Thursday 27 August session with 8 ft and strong cross-onshore winds might be worth a look. For paddle surfing, it’s a total write-off. The break is inconsistent, and this stretch proves it. Sometimes it’s just like that – a blank run. Leave the boards at home.
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.
