The Lowdown
G'day, I'm Rusty. Let me give you the rundown in feet and miles.
Alright, the story's the same. The next few weeks are a real struggle, but there's one day that's going to fire. Water temp is about 58°F, pretty normal for this time of year.
The first week and a half is a total dud. From Sunday the 2nd right through to Wednesday the 12th, it's all onshore slop, cross-shore chop, and tiny surf. The ocean's got no energy – most days the combined energy is in the tens or low hundreds. We're talking waves in the 1 to 3 foot range, mostly blown out or barely breaking.
Thursday the 13th gives you a tiny peek – glassy morning with a weak 3ft swell, but the energy is a measly 35. Then the afternoon jumps to 6ft, but it's onshore and messy with 200 energy.
Friday the 14th of August. That's the one. The morning is clean with a light offshore breeze. Swell is 7ft from the southwest, period around 7 seconds, and the energy is a solid 337. This is going to be a proper session – clean, powerful, and worth the wait. The afternoon glass-off is also worth a look with 5ft and 161 energy.
After that, it fades again. The weekend of the 15th and 16th is back to small, weak surf. The 16th might have a glassy afternoon with 4ft waves, but it's slow.
So, to sum it up: the first 12 days are a write-off. Your best bet is Friday the 14th of August. It's the only real window in the whole forecast.
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.
