The Lowdown
Alright, let's cut the crap. Rusty here, and I'm not gonna sugarcoat it: the next couple of weeks are looking proper bleak. We got a whole lot of flatness and dribble, with one messy, powerful pulse in the middle that'll only appeal to the kamikaze crew. You might as well wax your board now and get ready to stare at the horizon.
Water's about 57 degrees, which is par for the course around here.
The first sliver of hope doesn't even show up until Sunday, August 10th. The morning brings a bump of about 6ft from the southwest, but the period is a weak 6 seconds and the energy is only moderate (261). To make matters worse, the wind is howling onshore from the west-southwest at 30 km/h. It'll be a lumpy, blown-out mess. Not worth the effort.
Monday the 11th is more of the same. A 5ft northwest swell, but again, a short period and weak energy (99). With a 35 km/h cross-shore wind, it'll be choppy and all over the place.
Now, for the only real swell of the window, we look to Wednesday, August 13th. The morning shows a solid 8ft of west swell with a 7-second period and strong energy (632). But here's the catch: it's being thrashed by a strong 45 km/h cross-onshore wind. The report says it all: "strong cross-onshore and messy." The afternoon is similar, with 8ft from the west-southwest, but still with strong onshore winds. For a beach break like Aldinga Beach (Fleurieu Peninsula), this is a full-on washing machine. Honestly, this is more a kite-surfing day than a paddle-surfing day. Unless you're an expert looking for a beatdown, stay on the sand.
And then, just like that, the swell packs its bags and leaves. From Thursday the 14th all the way through the following week, we are faced with tiny, weak surf. There are moments of glassy conditions, like the morning of Sunday the 17th with a 0.6ft dribble, but it's completely unsurfable. The energy is barely a blip on the radar.
The only other thing worth a mention is Thursday, August 21st. The morning shows a 3ft southwest swell with a 5-second period, and light offshore southeast winds. It's got a bit of energy (67) and the report calls it "surfable waves but very ordinary conditions." It's not a standout, but it's probably the cleanest option on offer. Still, with that short period and weak energy, it's going to be pretty average.
So, there you have it. A long, drawn-out flat spell with one day of powerful, messy surf for experts only, and one day of clean but tiny waves if you're desperate. A pretty typical blank run for this stretch of coast.
Keep your head up and check back later.
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.
