Alright, Rusty here. Let’s get real about what’s happening in your local waters.
Honestly, mate, it’s a pretty grim run for the next 16 days at Aldinga Beach. The forecast is basically a write-off for any decent surf. There’s a big gap of poor conditions right through the weekend and into the middle of the week, with nothing clean and rideable.
Let’s break it down. Sunday the 12th starts with a messy 6 ft to 6 ft swell from the west, but the wind is a fresh cross-onshore at 19 mph, making it lumpy and ugly. The wave energy is weak to moderate (225 on Sunday morning, dropping to 162 by afternoon), and the period is a short 6 seconds, so it’s just wind chop. The score is flat zero. Monday continues in the same vein—a bit smaller, still cross-on, still choppy. Tuesday gets tiny, down to 2 ft, and the wind turns light onshore but the swell is weak (30 energy). It’s just not working.
Wednesday the 15th has a moment of glassy conditions in the morning with an easterly breeze at 3 mph, but the swell is only 1.0 ft with a 8-second period and a combined energy of just 12. It’s basically flat and not worth paddling out for. Thursday and Friday are the same story—tiny, glassy or clean, but no power at all. The energy numbers are in the single digits. You’re looking at a long stretch of nothing.
The next week doesn’t get any better. There’s a small pulse of 4 ft swell from the NNW on the morning of Thursday the 23rd, with a clean offshore wind from the ENE. But the period is a trashy 5 seconds and the energy is only 57. It’s not enough to get excited about. By the afternoon, it drops to 2 ft and glassy. The following days are similar—tiny, clean, but no swell.
The only real blip in the whole 16-day window is on Sunday the 26th afternoon, when a strong cross-onshore wind at 25 mph whips up a 6 ft swell from the WNW with a moderate energy reading of 263. But the wind is a strong breeze, the period is a short 6 seconds, and it’s described as “strong cross-onshore and messy.” That’s kite-surfing weather, not paddle-surfing weather. The setup is a beach break, so it’s going to be a washing machine.
The water temperature is about average for the time of year here at Aldinga, nothing unusual.
So, there is no standout. No hidden gem. The best you could ask for is a clean, glassy day with a tiny 1.0 ft swell, which is just a paddle float. The forecast is consistent in its inconsistency—it’s just a blank run. For a beach break like this, that’s not unusual in the winter. Forecasts can change, but right now, leave the board at home.
Stay dry,
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.

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.
