The Lowdown

G’day, Rusty here. Let’s be straight with you: the next couple of weeks are a write-off for getting a proper wave at Aldinga Beach. I’ve scanned the whole 16-day window, and there’s just nothing worth paddling out for. The ocean’s going to be flat and messy for the most part, so if you’re hanging for a wave, you might be better off finding something else to do.

The first week is basically a dead loss. From Saturday the 15th through to the following Thursday, we’re looking at ankle-biters—nothing over 0.7ft—with weak energy readings in the single digits. The wind is mostly cross-off or light, which would be great if there was any swell, but there isn’t. The water temp is sitting around 57°, which is about average for this time of year, so no surprises there.

There’s a glimmer of something on Friday the 21st. The swell bumps up to 3ft in the morning, and the energy ticks up to 52. But the period is a short 5 seconds, and the wind swings around to a fresh cross-onshore, making it lumpy and messy. By the afternoon, it pushes to 4ft with energy at 138, but the wind is up to 18 mph from the southwest, and the quality is just poor. That’s not a surf day; that’s a day to watch from the car.

After that, it drops back down to almost nothing for the rest of the month. There’s a little bump on the 29th—4ft in the morning, then 6ft in the afternoon with energy jumping to 291—but it’s a 5-6 second windswell, onshore, choppy. That kind of setup at a beach break like Aldinga is more interesting for kite surfing than paddle surfing. The period is too short, and the wind is going to ruin any chance of a clean face.

The long-range stuff into the start of September isn’t any better. Small, short-period leftovers and the wind never really lets up. Honestly, this is one of those blank runs where the sea just doesn’t want to cooperate. It happens here. I wouldn’t hold my breath, but forecasts can change—that’s the only hope I can offer.

Stay dry, folks.

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.
