The Lowdown

Gday, it’s Rusty here. Let’s be straight with you – the next couple of weeks are a write-off for any real surf at Aldinga Beach. I’ve got nothing good to paddle out for. The forecast is showing a whole lotta nothing, and when there is a pulse of energy, the wind is gonna be on it like a seagull on a chip, making it messy and blown out. It’s a tough stretch.
Looking at the first week, it’s all about waiting. The swell stays tiny, mostly under 1ft, with weak energy readings (max 33). We’ve got some cleaner conditions with north winds creating cross-off breezes, but there’s just no wave to push you around. The water temp is 57°, which is about normal for this time of year, so that’s not a surprise.
The only real bump of energy comes in on Sunday the 9th. The swell jumps to 5ft in the morning, but it’s a short-period, 5-second windswell with 102 energy behind it. By the afternoon it gets worse – 6ft at 6 seconds and 263 energy, but the wind is strong onshore from the WSW at 25 mph. This is a messy, stormy mess. It’s not for surfing; it’s more like a kite-surfing kind of day with that wind and lumpy water. That onshore push continues into Monday the 10th and again on Wednesday the 12th, with similar poor conditions.
After that, the swell just drops off a cliff again and we’re back to ankle-biters. It’s not until the second week that we see some life, but it’s still not anything worth getting excited about. There’s a very long-period, 14-second pulse from the SW showing up on Tuesday the 19th and Thursday the 21st, but the swell heights are only 0.3ft. That’s a lot of period with no power behind it. We’re talking about a complete flat spell.
So, what’s the call? There is no standout. There is no "best on offer." The entire 16-day outlook is a blank. This is a period where the board stays in the car, and you do something else. It’s a normal pattern for this area to just go flat, but it rarely stays poor for long. Forecasts can change; we just need some luck with the wind when a proper swell decides to show up. For now, keep the wax dry.

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.
