The Lowdown
G’day, Rusty here, your local surf reporter for Aldinga Beach. Let’s be straight with you from the start – this stretch of coast is looking pretty quiet for the next two weeks. The first few days are nothing to write home about, with hardly any swell and a lot of flat spells.
We’ve got a long gap of almost nothing from the start of the period right through to the end of July. The first real sign of life doesn’t show up until the morning of Thursday, 30 July. That morning, we’ll see a height of 5 ft from the west, with a period of only 6 seconds – that’s short-period wind swell, not much shape to it. The combined energy of all swells directed here sits at 163 (moderate), so there’s a bit of push, but conditions are described as “surfable but very ordinary.” The wind’s a light cross-offshore from the ESE at 6 mph, which will keep the surface clean. Still, don’t expect anything special – it’s a beach break, inconsistent, and the swell direction is west, not the optimum SW. For beginners, that 5 ft will be a bit of a handful, but it’s not too big for someone with a bit of experience.
The next morning, Friday, 31 July, offers a similar story – 3 ft from the SSW, period 5 seconds, combined energy of 79 (weak), with a light cross-offshore breeze from the ESE at 9 mph. Again, it’s clean but ordinary. The surf is barely rideable, and the consistency is poor.
After that, we’re back to tiny stuff. Saturday, 1 August, has a mere 0.7 ft from the WSW with a period of 9 seconds, but the wind is offshore from the E at 9 mph, making for glassy conditions. Still, it’s just too small to get excited about.
The rest of the window into early August stays small and weak. The water temperature is around 58°F with a -0.9°F anomaly, which is about average for the time of year. The standout here is the morning of Thursday, 30 July, with the biggest swell on offer, but it’s far from a classic. If you’re desperate, that’s your best bet. Otherwise, the kite surfers might find more fun in the choppy periods around 22 and 26 July, but for paddle surfing, it’s a long wait.

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.
