The Lowdown
G’day, Rusty here.
Look, I’m not gonna sugarcoat it – this stretch at Aldinga Beach is a desert for most of the next two and a half weeks. We’ve got a solid 11-day run of flat or near-flat conditions, with barely a ripple to get excited about from now through to the 21st of August. If you’ve got a longboard and a lot of patience, you might scratch out something tiny on the 15th or 16th when the wind goes clean and offshore, but really, you’re looking at ankle-biters under 0.7 ft.
The one bright spot – and I mean the only one – hits us on Sunday the 23rd of August. That morning the charts come alive. A solid 8 ft swell out of the WSW, with a period of 8 seconds, and it’s packing some punch – combined energy readings are right up at 725 (moderate to strong). The wind is light and offshore from the ESE, so Aldinga Beach should be clean with lined-up walls. That’s a proper session, but heads up – 8 ft is expert territory; if you’re a beginner, sit this one out. The swell drops off that afternoon to 5 ft, still surfable but not the highlight.
Before that, there’s nothing. After that, Monday the 24th has a weak 3 ft morning, and then it fades back to tiny slop. Water temps are sitting around 57°F – pretty average for this time of year, no real anomaly to speak of.
So for the full 16-day outlook: don’t bother packing your board until the 23rd. That Sunday morning is the one standout. Everything else is either flat or too small to mention. It’s a frustrating run for a normally inconsistent spot, but when it does turn on, it’s worth the wait.
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.
