The Lowdown
G’day, it’s Rusty here. Look, I’ve had a good look at the charts for Aldinga Beach, and I’m not gonna lie to you – it’s a tough one. This whole 16-day stretch is a write-off for any kind of decent surf. There’s just nothing on offer worth paddling out for. The swell is tiny, the energy is next to nothing, and the timing just isn’t there.
We’re looking at flat to knee-high slop for the entire run. From Friday, July 17, right through to Saturday, August 1, the swell height barely scratches 3 ft, and that’s the absolute best it gets, and even then the combined energy is only 37 (weak energy). Most days it’s down around 0.3 ft to 0.7 ft, with energy readings in the single digits or low teens. The wind is mostly cross-off or cross, which is fine, but there’s no wave to work with. A few windows of glassy conditions pop up – like Friday afternoon July 17 and Saturday afternoon July 18 – but you’d be sitting on a flat ocean. On the 27th of July, we get a tiny pulse of 3 ft swell from the west-northwest with a period of 5 seconds, but it’s cross-onshore and the energy is still only 37. That’s the biggest swell of the whole stretch, and it’s still basically nothing.
Because Aldinga Beach is an inconsistent beach break, this kind of blank run is more normal for the area. It’s not a spot that fires often, and when the swell is this low, it’s just not worth chasing. The water temp is sitting around 58°, which is about average for the time of year, so no surprises there.
Honestly, if you’re desperate to get wet, you’d be better off with a kite. The setup here looks more interesting for kite surfing than paddle surfing, with those persistent cross-shore breezes, especially on the 28th of July when the wind hits 19–22 mph. But for a surfboard? Nada. Keep the board in the shed, mate. The forecasts can change, but this one’s a long dry spell.

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.
