The Lowdown
Alright, Rusty here again. Let’s break it down for Aldinga Beach in the units that make sense to a lot of you.
We’re looking at a long, flat spell. From now until Monday the 15th, there’s pretty much no surf. The wave energy is super weak—numbers mostly in the single or low twenties, meaning barely any push. Water temp is around 58°, which is normal for the season.
The one day that fires is Tuesday the 15th, in the afternoon. Swell hits about 8ft from the W, with a short period of 7 seconds, but the combined energy registers at 771—that’s moderate. The wind is light and cross-offshore, so it’ll be clean. This is the standout, but at over 8ft, it’s strictly for the experts. That’s your best shot.
Wednesday morning the 16th still has some size at 6ft from the WSW, period 6 seconds, energy 249, with offshore winds. It’s a smaller follow-up but still clean.
After that, it fades back to tiny, weak conditions for the rest of the window. Friday the 19th morning shows another pulse at 6ft WNW, 6 sec period, energy 217, clean, but nothing that’ll blow your mind.
Bottom line: nearly two weeks of waiting for one solid, expert-only day on Tuesday the 15th afternoon. Everything else is barely a ripple.
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.

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.
