3 different a380s moving their rudders at the same time while parked at the terminals at LAX?

I'm at LAX and staring at the3 a380s parked at the gates across the way. Korean air, Lufthansa, Emirates. They finally settled and all facing hard left?

What force could be affecting nearly all of them at the same time and then uniformly in one direction?

To be fair, as a layperson, I never would have guessed that rudders can move in the wind because the engines/hydraulic system is offline and there is no electric lock. I thought it would be more like a parking brake where the hydraulics are gone but a manual/electric brake is on.

Air bleed off in the hydraulic systems. It's damn near impossible to get all the Air out of hydraulic systems.

With the hydraulics system unpowered, which is common when the aircraft are parked, the control surfaces are moved either by gravity (you can see this very often with ailerons and elevators), or by wind (usually the rudder).
