The Lowdown
Alright, folks, it's Rusty here, and I've got to be straight with you – this 16-day window for Aldinga Beach is a real bust. There's not a single session worth paddling out for. The guidance tells me this spot is already an inconsistent, beginner-friendly sandbank, and the forecast just confirms it's gonna be a long, flat stretch. Don't get your hopes up; this sort of blank run is pretty normal for the area, so it's not a huge shock.
Let's walk through it. Starting Sunday the 19th we've got a pathetic 0.3ft of swell from the SW, with a long period of 12 seconds but the energy is tiny (6) and the wind is cross-off, but it's just too small to do anything. Monday and Tuesday the 20th and 21st stay similarly tiny – 0.3ft to 0.7ft, light breeze, but the combined energy barely hits double digits (13, 16). Wednesday the 22nd brings a spike to 3ft, but it's a horrible short-period 5-second windswell from the WSW, onshore wind at 12 mph, and the energy is still weak (32). That's a complete mess. Thursday and Friday the 23rd and 24th are even smaller, with cross-on wind and chop. Saturday the 25th offers a moment of glassy conditions in the afternoon, but the swell is just 0.7ft with a 7-second period and energy of 5 – you'd need a toy board.
Then Sunday the 26th is flat in the morning, and the afternoon has a 2.3ft windswell but with a strong cross-shore wind. Monday the 27th is the biggest day of the run – 6.6ft in the morning, 6.9ft in the afternoon, both from the WSW with a short period (7 seconds). The combined energy jumps to 366 and 374, which is moderate wave energy, but the wind is howling at 25 mph – cross-off in the morning, cross-on and messy in the afternoon. That's way too big for beginners, and with that wind it's unsurfable for anyone. Honestly, it looks more like a kite-surfing setup than a paddle session. After that, Tuesday the 28th through to the end of the period on Monday the 3rd of August is a slow fade – tiny swell, often flat, with occasional light winds but no real push.

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.
