The Lowdown
Alright, gather 'round. Rusty here, and I've gotta be straight with you - this outlook for Aldinga Beach is a tough one to write. We're looking at a pretty bleak 16-day window, so let's break it down.
For the next week and a half, it's mostly a write-off. We've got tiny, weak swell and a lot of onshore wind messing things up. The first real pulse of energy that shows up is on the 27th of July, with a 4 ft swell from the NNW, but it's paired with a fresh cross-offshore wind, so it's going to be lumpy and bumpy. The combined energy is only a weak 66, so don't expect much push. Then things get worse. On the 28th of July, the swell jumps to 7 ft from the WSW, but the wind is a howling 22 mph from the W, making it a messy, choppy mess. The energy is moderate (410), but it's not worth paddling out for. This setup is more interesting for a kite surfer than a paddle surfer, honestly.
The best chance we get is Sunday, the 2nd of August. The water temp is about 58°F, which is just a touch below average for this time of year, nothing to write home about. The swell is small at 2 ft from the WSW, but the wind goes glassy in the morning. With a period of 10 seconds, it's got some decent shape, and the energy is a weak 71. The forecast calls it "surfable waves but very ordinary conditions," and I'd agree. It's clean, but it's tiny. Aldinga Beach is an inconsistent spot, so this kind of blank run is a bit more normal for the area. It's a beginner-friendly break, but with the size being so small, it's only really for a longboard or a funboard.
And then Monday the 3rd of August, we get another glassy morning with a 3 ft swell from the WSW. The energy is 75, still weak. It's surfable, but again, very ordinary. The crowds are listed as "often" here, so you might have some company for those tiny waves.
So, to be honest, there's no standout session here. The best on offer is the 2nd of August morning, and even that's a stretch. Don't get your hopes up.
Rusty.
