The Lowdown
Alright, let me tell ya, it's Rusty here, and I've gotta be straight with ya – the outlook for the next couple of weeks at Aldinga Beach is a real tough one. We're looking at a long, dry spell with barely a ripple worth paddling for.
The water temp is sitting at 57°F, which is about average for this time of year, nothing to write home about.
We kick off Tuesday the 11th with a northerly breeze howling at 19 mph, making a mess of any small swell. That combined wave energy is a weak 64 out there. Wednesday the 12th holds a little more size with 4ft swell from the WSW, but it's blown out by more strong onshore wind. Thursday and Friday are tiny, just 1ft junk.
Honestly, from the 11th right through to the morning of Sunday the 23rd of August, it's just a depressing run of tiny surf with a combined wave energy that barely cracks double digits. We're talking flat spells with 0.3ft swells and long period groundswell from the southwest that just doesn't have any oomph to stand up. The winds are mostly offshore or clean, but there's nothing to ride.
Then, finally, on the morning of Sunday the 23rd, a little pulse arrives. We get a 4ft swell from the southwest, period is a short 6 seconds, and the wind goes glassy. The wave energy climbs to a moderate 88. It's not a standout by any stretch, but after nearly two weeks of nothing, it's the most interesting we've got. The waves are surfable, but the conditions are still only ordinary. This is the only real option the whole forecast offers.
The rest of the 23rd and into the final days of the forecast, the swell just fades away back to nothing with glassy conditions but no waves.
So there ya have it. A long wait for a very average, short-lived window. Skip the board for the kite if you've got one; that wind's gonna be better for it than the surf for most of this period.
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.
