The Lowdown
G’day, it’s Rusty here. Let’s be straight with you: the next couple of weeks are looking pretty flat and grim for Aldinga Beach. The models are showing basically nothing but tiny, weak leftovers for the entire outlook. There are no standouts, no days to circle on the calendar. It’s a long stretch of near-zero wave energy, so if you’re chasing a wave, you might want to find another hobby for a bit.
Looking at the first few days, Tuesday the 8th is completely dead, with a 0.3ft dribble and not enough energy to push a leaf. The water temp is sitting at 58°, which is normal for this time of year. Wednesday the 9th pulls in a slightly bigger bump of 2ft, but the period is a short 4 seconds and the wind is a fresh 30 km/h SSE cross-off. It’s clean-looking, but that’s about it. There’s no push, and the energy reading is a weak 17. Not worth a paddle.
From Thursday through to the middle of next week, we’re stuck in a rut. Swell heights hover around 0.3ft to 1ft with periods all over the shop, mostly under 10 seconds, and energy readings consistently below 20. A lot of glassy mornings, like Friday the 11th and Saturday the 12th, but glass on flat water just means a nice lake, not surf. Sunday the 13th gets a little bump to 1ft but with a 5-second period, it’s just wind chop. Forget it.
The only glimmer of anything happens on Friday the 18th. We finally see some actual swell energy—3ft in the morning jumping to 4ft by the afternoon, with the energy reading climbing to 102, which is moderate. But look closer: the period is a weak 4 to 6 seconds. That’s short-period windswell, not a groundswell. It’ll be lumpy, disorganized, and with a cross-shore wind, it’s not going to offer much for a paddle surfer. If the wind picks up, this might be a session for the kites rather than the boards.
After that, it fades back into the flat nothingness for the rest of the window. By the 20th and beyond, we’re back to 0.7ft dribbles and low energy.
It’s a rough patch, no two ways about it. Aldinga can be inconsistent, and this is one of those blank runs that’s more normal for the area than we’d like. But it won’t stay poor forever—forecasts change, and the ocean always has a way of waking up. Keep your eye on that Friday the 18th, but don’t hold your breath. For now, the board stays in the shed and the coffee stays hot.
Rusty.

A general guide to surfing at Aldinga Beach can be found by selecting the local surf guide option on the grey menu.

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.
