The Lowdown
Right then folks, Rusty here. Let’s be straight with you – this 16-day window for Aldinga Beach is a pretty grim stretch. There’s nothing to get excited about, no standouts, and the forecast is a long, drawn-out run of poor surf conditions. We’re looking at a solid block of days with virtually no wave energy, so the first thing to do is just brace yourself for a wait.
The light at the end of the tunnel is a long way off. The earliest sniff of anything remotely surfable doesn't arrive until Friday, 11 September, with a small swell of 4ft from the WSW. That period is a weak 6 seconds, so it’ll be a bit of a messy, short-period wave. The wind will be a light cross-off from the ESE, making it clean, but the overall energy is weak (119). For a couple of days after that, it drops back down to tiny 1ft waves.
Before that, it’s a write-off. We have a massive gap of nearly two weeks of absolutely nothing. The earlier days show a lot of strong, onshore winds, particularly around the 6th to 8th of September, where we see 10ft to 12ft of messy, wind-blown swell with very strong energy (875 to 1790). With the strong cross-on and onshore wind, and the beach break setup, that's far more interesting for kite surfing than paddle surfing – a solid no-go for us.
So, the pick? It has to be that Friday 11th September afternoon session, just because it’s the only thing on offer. But it’s a very poor option. The only positive is that the wind is clean. If you’re desperate, you might get a few grovelly ones. Keep an eye on it, but don’t plan a trip around it.
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.
