The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this is a tough one. For the next week and a half, we’re looking at a real flat spell. There’s barely a bump to get excited about, and the northeast wind is only good for keeping the water glassy, not for pushing in any real waves. The only swell that shows up worth talking about is a pulse of energy that arrives on Friday, August 21st, and it’s the one bright spot in an otherwise bleak 16-day window.
The water at Aldinga Beach is sitting right about average for this time of year, so no surprises there.
The long wait for anything rideable ends on August 21st. Friday morning sees a bump of swell at 5 ft from the WSW, but the period is a short 6 seconds, so it’s going to be a bit of a messy, wind-swell affair. The combined energy is moderate (123), which is the only real kick of energy in the whole forecast. The wind is a clean cross-off from the north at 12 mph, so the surface will be clean, but that short period means the waves will be weak and crumbly. It’s not a day for a step-up board; grab a groveler.
That same afternoon the swell drops to 3 ft but the wind backs off to 9 mph, still cross-off, so if you’re just desperate for a paddle and a few knee-high crumpets, it’s your best bet of the 16 days. Even then, it’s calling it “poor surf conditions.” For a beginner, that 5 ft swell is going to feel a bit much, but for anyone else, it’s just underwhelming.
After that, it’s back to the doldrums. The rest of the run is flat, with tiny 0.3 ft to 1 ft waves and consistent north winds. The setup is so weak that on a beach, it’s honestly more interesting for kite surfing than paddle surfing. There’s a few glassy mornings on the 19th and 20th with 0.3 ft waves, but that’s pond conditions.
Bookmark that Friday the 21st. It’s not a hero day, but it’s the only game in town.
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.
