The Lowdown
Alright folks, it's Rusty here. Let me be straight with you – we’ve got a rough patch ahead. The finder is showing a big fat zero for the entire 16-day outlook at Aldinga Beach. There’s no surf to get excited about, so I’m just gonna walk you through why and what you can expect if you’re still keen to get wet.
The forecast starts now and we’re looking at a long stretch of nothing. From Monday, September 7th, right through to the end of the period on September 22nd, the wave energy is almost non-existent. The combined energy is often in the single digits or low teens, way below 100, which is just weak. Swell heights are tiny, mostly 0.3 ft to 0.7 ft, and the period is short and messy. It’s a classic flat spell for this inconsistent beach break.
On Monday the 7th, we’ve got a bit of a cross-shore breeze and some tiny 0.7 ft swell from the WSW, but the energy is only 17. It’s poor. Tuesday the 8th sees a brief moment of glassy conditions, with a light NW wind, but the swell is just 0.3 ft. The water temp is about 58°, which is pretty normal for this time of year, so no surprises there.
The best of a bad bunch might be the morning of Monday, September 21st. The wind is light and offshore from the NE, and the swell bumps up to 3 ft from the W – that’s the biggest we’ll see. The energy is 40, still weak, and the period is a short 5 seconds. It’s a small, weak windswell. For a beginner, that’s small and clean, but for anyone else, it’s barely a ripple. Aldinga Beach is a beginner spot anyway, but this is just not worth the trip.
The whole run is a blank. It’s a flat, inconsistent period for the area, and that’s just how it goes sometimes. Forecasts can change, but right now, don’t bother paddling out. Keep the board in the car.
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. If you surf the same spot (Aldinga Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
