The Lowdown
Right, grab a coffee and listen up. Rusty here.
To be straight with you, the next sixteen days are looking bleak for Aldinga Beach. We've got a massive stretch of flat, messy, or just plain ugly conditions before anything remotely rideable shows up. The water temp is sitting around 58°F which is pretty average for this time of year, nothing unusual there.
From now through to the 24th of September, it's a write-off. We're talking tiny swell, mostly under 3 ft, and when there is a little bump, the wind is all wrong – onshore, cross-onshore, strong breezes. The combined wave energy is pathetic, often single or low double digits (like 8, 20, 33). It’s just not worth getting wet.
There’s a flicker of hope on Friday the 25th. The morning shows a 4 ft swell from the SW with a gentle offshore from the NE, so the surface should be clean. The afternoon picks up a touch to 4 ft from the SSW, with cross-offshore winds keeping things tidy. The energy finally gets into three digits at 109, but it's still a short-period swell at 5 seconds. It's surfable, but very ordinary – it’s the best we’ve got, and that’s saying something. This is the one day in the whole 16-day window that might tempt you, but keep expectations low.
After that, it’s back to tiny, wind-affected slop right through to the end of the period. There’s simply nothing else on the table. For the Aldinga area, a run this barren isn't totally unheard of, but it stings.
Rusty, signing off.

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.

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.
