The Lowdown
Alright, Rusty here, let's talk about what's on the menu for Aldinga Beach over the next couple of weeks.
Well, I gotta be straight with you, it's a pretty grim picture for the next week and a half. We're looking at a long stretch of nothing much. From now until the morning of Saturday the 6th of September, the surf is basically flat. There's a few tiny bumps showing up, but nothing you'd bother paddling out for. The wind is messy, the swell is tiny, and it's just not happening. It's a real bummer.
Then, on the morning of Sunday the 6th of September, things get a bit interesting, but not in a way most of us will enjoy. The swell jumps up to a solid 10 ft from the WSW, and the combined energy is a powerful 953 – that's a serious pulse of energy. But the wind is a fresh cross-offshore from the north, which should keep the faces clean. The problem is, at that size, 10 ft is well into the realm of experts only. It's gonna be a heavy, powerful wave, and the period is a short 8 seconds, so it'll be a bit of a washing machine. Definitely not for beginners.
By the afternoon, it gets even bigger, hitting 12 ft with a combined energy of 1732, but the wind swings NW and becomes a strong cross-shore, creating a messy cross-chop. That's a write-off.
The next few days, the swell drops back down, but the wind is mostly onshore or cross-onshore, keeping the quality poor. The morning of Tuesday the 8th of September has a little 3 ft swell, but it's onshore wind, so it's a no-go.
Honestly, if you're looking to paddle, this whole 16-day window is a dud. The cleanest wave we see is on the morning of the 6th, but it's so big it's only for the brave. For the rest of us, it's a waiting game. The good news is, Aldinga Beach is a pretty consistent spot, so this blank run won't last forever. The forecasts can change.
For the rest of the period, it's flat or blown out. The swell direction is always from the SW or W, which is the optimum for Aldinga, but the wind is just never our friend.
Keep your wetsuit on and your eyes on the forecast, but for now, I'd say take a break. This is a tough one.
Rusty.
