The Lowdown
Grab your board, but maybe leave it in the car for a while. The next couple of weeks are looking pretty flat and grim for Aldinga Beach. Honestly, there's nothing here that I'd paddle out for. The swell window is just not lining up, and we're staring down a long stretch of tiny, weak, and mostly messy waves. We're talking a full 16-day run of "poor surf conditions" across the board.
The only real pulse of energy shows up on Saturday the 5th, with a W swell pushing 7ft at 7 seconds, but it comes with a 19-22 mph onshore W wind. That's a classic blown-out, choppy mess. The combined energy is a solid 485, so there's power in the water, but it's all wind-chop and closeouts. It's more of a kite-surfing day than a paddle-surfing day, to be honest. That's the only time we even get close to a real wave, and it's a write-off.
Before that, it's ankle-biters. The easterly swells earlier in the week are too small and short-period to do anything. We see a bit of WSW groundswell at 1ft on Friday the 4th, but it's inconsistent and weak.
After that Saturday bump, it just fades away. Sunday the 6th through the end of the window sees nothing but 0.3ft to 2ft slop. There are some glassy windows, especially Sunday afternoon the 6th with a light SSW breeze and pure glass, and Monday morning the 14th is also dead calm. But with no swell, it's just a flat, pretty ocean. The periods get long at times—15 seconds on the 9th and 14 seconds on the 12th—but there's just no height behind them. It's a lake out there.
Aldinga is looking pretty inconsistent right now, which is its usual character anyway. It's exposed, but that doesn't matter when there's nothing to expose. For a beginner, even the tiny days are a bit of a mission. The water temp is 59°, which is about normal for this time of year.
I hate to say it, but this is a two-week blank. We don't have a single standout, not one. It's just a waiting game. Forecasts change, so don't lose hope, but for now, the board stays in the shed.

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.
