I rode the Busan Air Cruise yesterday that uses the same cabin as the Skyline. The wind was about 25 gusting to 35.
The Busan system is pretty cool, there are only two main towers that are both very high (just a guess, the first one is probably 80' and the second around 120') and there is a lot of sag between the towers.
Even in the high, gusting wind in a cabin by myself I mostly didn't feel the wind. The only time I noticed it was immediately leaving the station and when I first went behind a mountain that probably changed the direction. You could see the other cabins moving a little but not much.
Going across the uphold sheaves was very smooth, but you could feel the down hold ones a but more. Probably the thing I felt the most was when there cabin in front of me went across the down hold sheaves. The cabin in front of me and two people in it that were moving a lot, but I never felt that movement.
The cabins were only being launched every 35 seconds, with 4 in the station at a time. The way it was set up, you'd have 25ish seconds to unload and 25 more to load, which is about the same as the Skyliner.
ETA: Although they had the 10-person gondolas, they maxed then at 8 people. The assumed weight pp was 70 kg (154# each).
