The Lowdown
G’day, Rusty here. Gotta be straight with you—there’s nothing worth paddling out for in the 16-day window, from August 9 right through to August 24. Not a single session pops. The finder’s given us a blank run, and looking at the guidance for Aldinga Beach, it’s a tough stretch. The break’s inconsistent at the best of times, so a dry spell like this isn’t totally out of character. Still, forecasts can shift, and it won’t stay poor forever.
The whole period is plagued by onshore and cross-onshore winds from the SW and WSW, with only a few fleeting moments of lighter breezes. The swell barely gets off the ground—most of it sits at 0.3 ft to 1 ft, with a weak combined energy (single-digit to low-double-digit values). A small pulse shows up on August 10 morning with a 5.6 ft WSW swell and moderate energy of 216, but it’s blown out by a fresh 18.6 mph onshore wind, making it a total mess. That pattern repeats around August 20 afternoon, with a 5.2 ft WSW swell and 183 energy, but again, choppy cross-onshore winds spoil it. For a spot like Aldinga Beach, which is fairly exposed to SW swells and needs that direction, the wind just kills any chance of shape. There’s no standout day, no clean swell window—just a long, flat, windy gap.
Hang in there, check back later. This is one to sit out.
