The Lowdown

Oi, Rusty here. Let’s be straight with you – the next 16 days for Aldinga Beach are a proper write-off. There’s not a single surfable wave on offer. The whole stretch from Tuesday, 18 August, right through to Wednesday, 2 September, is filled with zero-rated conditions. That’s over two weeks of nothing.

The swell is tiny, mostly under 2ft, with weak energy readings that barely crack double digits. The combined energy of all swells directed here is essentially flat, with values like 2, 5, or 10, which is barely enough to ruffle the surface. The only time the energy gets a bit of a pulse is on Thursday, 27 August, when a 7ft swell from the west shows up, hitting a combined energy of 396 (moderate wave energy), but the wind is a fresh onshore or cross-onshore, making it a messy, blown-out mess. It’s still written off as “poor surf conditions.” The period on that swell is a short 7 seconds, so it’s just windswell junk.

The water temperature is sitting at 57°F, which is about 0.5°F cooler than the long-term average – nothing to get excited about, just standard chilly water for the time of year.

Even the brief moment of glassy conditions on Monday, 31 August, and Tuesday, 1 September, only shows a 0.3ft swell. There’s zero push. Aldinga Beach is an inconsistent spot at the best of times, and a blank run like this is more normal for the area. It’s not a place that gets reliable surf, and this forecast proves it.

Honestly, if you’ve got a kite, you might get a look in on that 27 August westerly, but for a paddle surfer? Leave the board at home.

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.
