The Lowdown

G’day, it’s Rusty here.

Honestly, looking at the charts for Aldinga Beach, I’m scratching my head. We’ve got a solid 16-day window ahead of us, but basically every single session is a write-off. There are no recommendations coming through, no good surf options on the cards. That’s a blank run, plain and simple, but for this stretch of coast, it’s not unusual for it to stay flat and messy. The conditions just aren’t lining up. We might see a few pulses of swell here and there, but they’re always getting chopped up by onshores or dying out before they get anywhere near the beach. It tends not to stay this poor for long, though, so forecasts can change, but right now, I wouldn’t bother getting the wetsuit wet.

Let’s walk through it. The start of the period, Saturday the 8th through to the morning of Sunday the 9th, is pretty weak, with barely a ripple. There’s a bit of a cross-off breeze, but the swell is just nothing, maybe a foot or so. You’d be floating more than surfing. Then later on Sunday the 9th and into Monday the 10th, the swell does try to push in a bit, coming from the NW and WSW, but it’s short-period windswell, only 5 to 6 seconds, and the wind is either cross or onshore. The water’s going to be lumpy and messy. Wave energy gets up there on Monday morning, but with that poor quality, it’s just a washing machine.

Tuesday and Wednesday look a bit more active, but not in a good way. We’ve got a bigger pulse of swell, up to about 8 feet on Wednesday morning from the west with a moderate amount of energy. But the wind is cross-onshore or onshore and fresh. For a beach break like this, that’s going to be a complete mess. That size, over 5 feet, is already too much for beginners, and with the wind howling onshore, it’s not even that fun for experts. If you’re into kitesurfing, this might look interesting, but for paddle surfing, I’d give it a miss.

After that, the energy just drops off a cliff. The rest of the period, from Thursday the 13th all the way out to the 23rd, is mostly tiny, sub-3-foot slop. There is a moment on Friday the 14th morning when the wind goes glassy, which is a nice change, but there’s only about 1 foot of swell. That’s a fun idea if you’ve got a foamboard and just want to bob around, but there’s no real wave to speak of.

We’ve got a few other glassy or clean windows later in the week where the wind drops out, like on Tuesday the 18th afternoon, but again, you’re looking at a meagre half a foot of swell. The period out to the 19th does show some long-period swells, 15-16 seconds, which is a classic sign of proper groundswell, but the height is just completely absent. It’s all bark and no bite. So, bottom line, there’s nothing worth getting excited about. The standouts? There aren’t any. Save yourself the trip and maybe go for a fish instead.

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.
