The Lowdown
Alright mates, Rusty here. Let’s have a look at what’s cookin’ for Aldinga Beach over the next 16 days.
Honestly, it’s a pretty quiet stretch for most of it. From Thursday the 13th of August right through until Friday the 21st, the swell is tiny, barely hitting 1 feet most days, and the combined energy is in the weak zone, mostly under 30. That’s not surf, that’s just a lake with a breeze. Water temp is about 57°, which is dead average for this time of year. The wind’s mostly cross-onshore, so it’s choppy and messy. You get some light offshore breezes from the 17th to the 19th, but there’s just no swell to ride. It’s gonna be a frustrating wait.
There is one big outlier, and it’s a serious one. On Saturday the 22nd of August, a strong swell hits. In the morning, we’re talking a solid 15 feet from the WSW with a period of 9 seconds and a combined energy of 2909. That’s powerful. Wind is cross-onshore from the SSW at around 12 mph, so it’s gonna be chopped up. This is well over 8 feet, so it’s experts only. Honestly, with that wind and that size, this break looks more interesting for kite surfing than for a paddle session. The swell drops off a cliff after that, back to flatness for the rest of the month.
So here’s the rundown: if you’re a charger and want a piece of that big, messy swell on the 22nd, go for it, but don’t expect it to be clean. For everyone else, this is a long, quiet period. Forecasts can change, but for now, it’s a slow one.
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.
