Table - best surf conditions forecast for Aldinga Beach over the next 16 days.
Alright, Rusty here. Let’s be straight with you. Right now, and for the entire 16-day window we’ve got on the books, Aldinga Beach is as flat as a day-old beer. We’re looking at a solid stretch of nothing, I gotta call it.
The first ten days are a total write-off: poor surf conditions, weak swell – the best combined energy we see in that whole first block is a measly 76 (combined energy of all swells directed here). That’s barely a ripple. Monday the 13th is a write-off with onshore wind, and for the rest of that first week and into the second, the swell heights are either 0.3 ft or 0.7 ft. Tiny. On Wednesday the 15th, there’s a moment of glass with a 1.0 ft, eight-second swell, but honestly, you’re better off sitting it out.
Mornings on the weekend of the 20th and 21st show a bit more hope, picking up to 0.7-1 ft with some cross-offshore breeze, but the energy is still in the dumps (13 and 19). It’s clean, but there’s no grunt in the water. Then we hit Wednesday the 22nd – don’t even bother. A near gale from the NW at 31 mph with 1.0 ft swell is pure blown-out chaos.
The second week closes out the same way. From the 24th of July right through the morning of the 28th, we’re back to ankle-biters – 0.3 ft to 1.0 ft – with more onshore winds and choppy junk.
There is no standout period. No hidden gem. The only thing this stretch is good for is fixing your dings and saving your energy. Aldinga Beach is inconsistent at the best of times, and this forecast is a blank run. It’s not normal for it to be this quiet for this long, but we ride what we get. Forecasts change.
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.
