The Lowdown
G’day, it’s Rusty here.
Straight up, I’ve got to be honest with you—this stretch of coast is looking properly flat and messy, with nothing worth paddling out for over the next couple of weeks or so. We’re looking at a pretty grim run, and if you’re chasing waves, you might be better off dealing with chores or watching replays.
The only spot on the radar is Aldinga Beach, a beginner-friendly stretch that is pretty inconsistent these days and usually only turns on when a solid SW swell lines up. Looking at the guidance, the optimum direction is from the SW, and while we do see some of that direction at times, the size is mostly tiny and the winds are usually ruining any chance of clean surf.
The first hint of anything that moves comes on Monday the 10th, with a short-period WSW swell pushing in around 6ft. But it’s a lumpy, onshore affair with a fresh breeze, so it’s going to be a messy close-out. The combined energy is moderate (238) but with a period of only 6 seconds, it’s going to lack any real punch and just look like whitewater. That’s a miss.
The wave heights stay in that 4ft to 6ft zone through Tuesday and Wednesday, but the winds keep swinging onshore or cross-onshore, keeping things choppy and poor. Not a single clean option on offer.
By Thursday the 14th, things start to fade out completely. While we get a glassy morning, the swell is a desperate 1ft and the energy has dropped off the cliff (15). It’s flat, plain and simple.
Then we hit a proper dead zone. From Friday the 15th through to Sunday the 24th, we’re looking at ankle-snatchers at best, with most days offering 0.3ft to 0.7ft of swell. There are a few mornings with offshore or glassy conditions—like the 17th, 18th, and 21st—but you’d be surfing nothing. It’s a long, drawn-out gap with no real swell on the horizon.
There’s a tiny uptick right at the end, on Friday the 21st, when a small 1ft WSW bump shows up in the afternoon with glassy conditions. The energy is still low (58) but at least it looks pretty. Same story on the morning of Saturday the 22nd, with a weak 2ft SSW pulse, but it’s cross-off and clean, not doing much.
Honestly, the takeaway here is that there are no good surf options within the 16-day window. The entire run is poor, and with such an inconsistent set-up, a blank run like this isn't that abnormal for the area. The longer-range stuff is just too far out and the signals are too weak to get excited about. The water temp looks to be about average for this time of year, so the 5/4/3mm steamer will do the job.
Keep the board in the car just in case, but don’t rush. The first truly clean swell looks like a promise for another day.
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.
