The Lowdown
Righto, let’s talk about Aldinga Beach. Straight up, I’m looking at a 16-day window and honestly, for the first couple of weeks, it’s a ghost town out there. You’ve got a lot of days where the swell is tiny, and the wind is all over the shop. The first proper surf that’s worth paddling out for isn’t until Sunday the 13th of September. So, you’re looking at a solid gap from the start of the forecast right through to that date with nothing really rideable.
The water temp at Aldinga Beach is sitting around 58°, which is pretty much bang on average for this time of year, so nothing wild there.
Now, Sunday the 13th of September afternoon is the only real standout in the whole forecast. The swell bumps up to 6 ft, coming out of the west. That’s a big step up from the dribble we’ve been seeing. The combined energy of all swells directed here is 212, which is moderate wave energy, so it’s got some push. But here’s the catch – it’s glassy. The wind is basically calm, and it’s describing the conditions as glassy. That is a massive positive for Aldinga. You’ll get clean, smooth faces. The swell period is 6 seconds, so it’s a short-period wind swell, which means it’ll be a bit fat and dumpy, but with that size and that wind, it’s the best option on offer. For a beginner spot, 6 ft might be a bit much for absolute beginners, but for those with a bit of water time, it’s a goer.
Monday the 14th of September morning has 5 ft from the west-southwest, with a combined energy of 145 (moderate), and offshore wind from the north. That’s clean, but the period is still short at 6 seconds. It’s a decent option, but the Sunday glass-off is the real pick.
The rest of the week after that stays small and messy, with winds swinging around and cross-onshore chopping things up. The swell direction is mostly from the southwest, which is the optimum direction for Aldinga, so it’s got the right angle, but the size and wind just aren’t cooperating.
So, to sum it up: you’ve got a long wait. The standout is Sunday the 13th of September afternoon. Get out there for that glassy window. It’s not perfect, but it’s the only real wave in town.
