The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the next couple of weeks are about as flat as a politician’s promise. The finder is showing a big fat zero for any rideable surf. We’re looking at a dry spell that stretches from now, all the way through the 16-day window, with zero recommendations coming through.
Aldinga Beach is the only spot on the cards, and it’s a classic beginner-friendly, rarely-consistent bank that’s *fairly exposed* to the southwest. The problem is, there’s just no swell. We’re talking wave heights barely breaking the 0.3 ft to 0.7 ft mark for most of the run. The few times we get a pulse, like on the morning of the 28th of August, we see a tiny 0.7 ft from the WSW with a weak energy reading of 21 (weak energy), but it’s barely a ripple. The water temp is sitting about average for the time of year, nothing wild.
The winds are a mixed bag. We get a few glassy mornings – the 26th of August, the 28th of August, and the 8th of September all have that “glass” wind state and a slight air, which would be a dream if there was any swell. The 27th of August morning has a clean cross-offshore breeze from the north at 9 mph, which is a nice direction for Aldinga, but again, with only 0.7 ft of 8-second windswell, it’s not going to get you out of your wetsuit. The long period swells we see on the 28th of August afternoon (16 seconds) and the 30th of August morning (12 seconds) are from the SW, but they’re so small (0.3 ft) they’re not going to do anything. The combined energy barely cracks double digits for most of the month.
The second week is even more of a washout. From the 1st of September onward, we’ve got strong northerly winds hitting 19 mph on the Tuesday, just blowing the tiny scraps to bits. The 9th of September sees a slight uptick in swell to 2 ft from the SSW, but it’s short-period (5 seconds) and the wind is onshore and choppy. That’s not surf, that’s a washing machine.
Look, Aldinga is an inconsistent spot, and this run is a classic example of a blank period. It’s not a surprise for this area. The good news is it tends not to stay this poor for long, and forecasts can change. But for now, leave the boards in the shed. This is a write-off.
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.

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.
