Alright folks, it’s Rusty here, and I’ve gotta level with ya – it’s gonna be a tough stretch for anyone looking to get wet around here. The next couple of weeks are looking pretty grim, with barely a pulse in the water for most of it. We’ve got a long, dry spell ahead, so don’t be holding your breath.
We start off this Sunday, July 12th, and straight away it’s a no-go. The swell at Aldinga Beach is a weak 5ft from the West, but that 19 mph cross-onshore wind is just shredding any chance of a decent wave. The combined energy is only moderate (141), and it’s lumpy and poor.
This poor run of tiny, wind-blown surf is set to continue right through the week and into the next. Monday the 13th, Tuesday the 14th, Wednesday the 15th – all offering next to nothing. We’re looking at swell heights dropping to 1ft or less with energy values sinking to single digits. It’s flat, it’s clean on a few mornings, but there’s just nothing to ride. Even when we get a glassy morning on the 15th, the swell is a pathetic 1ft at 8 seconds. You’d need a stand-up paddleboard just to stay afloat.
The only tiny glimmer comes right at the end of the forecast period. Keep an eye on Wednesday, July 22nd in the afternoon. We finally see a pulse of energy, with the swell jumping to 5ft from the WSW, pushing the combined energy up to a moderate 164. The wind is light and cross-offshore, keeping things clean. It’s still a short-period, messy-looking swell, but if you’re desperate, that’s your only real window to find something surfable. After that, Thursday the 23rd goes glassy again, but the swell collapses back to nothing.
Later on, Friday, July 24th in the morning shows a bigger 6ft swell from the West, with moderate energy (284). But the wind is a messy cross-shore, the period is a short 6 seconds, and the forecast calls it marginal. That’s a messy, blown-out two-metre close-out machine on a beach break. Unless you’re an expert on a tow-board and a fan of whitewash, it’s a pass.
To be honest, the whole 16 days is a write-off. The swell is inconsistent, and the few moments with any size are ruined by onshore winds or short, weak period. It’s one of those blank runs that’s pretty standard for this time of year. Hang loose, and check back in with me – forecasts can change.
Rusty.

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.
