The Lowdown
Alright, Rusty here again. Let’s break it down for the yardstick crew.
The forecast for Aldinga Beach is a real flat spell over the next 16 days. The only recommendation is a no-go, so we’re looking at a long stretch of nothing burgers. The first several days have barely a ripple, and the pattern holds all the way through. It’s one of those runs where you’re better off checking the tide pools.
The water temp is sitting about 58°, which is standard for the season, so no surprises there.
Looking at the details: Wednesday the 15th has a tiny 1 ft swell from the WSW with a period of 8 seconds, and it’s glassy. The combined wave energy is only 12, which is pathetic. It’s too small to do anything with. Thursday the 16th is even smaller, around 0.7 ft, with the energy dropping to 6. Wind is light and clean, but no push.
Friday the 17th is down to 0.3 ft, and the energy is a measly 1. The swell is from the W with an 8-second period. It’s flat.
The weekend of the 18th and 19th sees a slight change with a longer period around 13-14 seconds from the SW, but the height is still only 0.3 ft, and the energy is in the single digits to low teens. That long period just means longer waits between nothing. Wind is cross-off or glassy, but it doesn’t matter when there’s no wave.
The whole of the following week, from the 21st through the 27th of July, is a mix of tiny 0.3 ft to 0.7 ft swells. The wind stays light to moderate, but the wave energy barely cracks 15. The late window on the 22nd Wednesday gets a bump in wind, with a 2 ft NNW swell, but the period is a short 4 seconds and the wind is a moderate cross-shore, making for a messy, weak setup. More of a kite day.
The final days of the month, the 28th through the 30th, are more of the same. Tiny swell, modest energy, nothing to get excited about. The 30th Thursday sees a 0.3 ft SW swell with a fresh cross-onshore wind, which is a write-off.
So, the honest truth is there’s no standout session here. The whole 16-day period is a blank run, and for this area, that’s not unusual. It’s a waiting game. Keep an eye on the charts, but for now, leave the board in the car.
Rusty.

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.
