Gusts can be absurd, but avg windspeed at the summit is 50 mph / 80 kph.

I've sparked up in that level of wind before, multiple times, with an old school zippo, a good decade or so of being a chronic smoker'll teach you how to do that.

Granted... your footing is probably just a teensy bit more of a thing you're gonna have to be aware of, hahaha!
