Highly unlikely you will get any decent stable flight time.
Unless you go massive, in which case you will introduce other issues.
A lot of this is highly dependent on the amount of turbulence of the wind. I've seen multicopters fly in 60 mph wind, if it's an off-shore breeze that is very "smooth. And then 20 mpg wind can be devastating if you're flying near any obstacles like trees or buildings.
generally the aerodynamics comes into play a lot in terms of the frame you choose especially under windy conditions. Also depends how well your copter (I assume) is tuned. I have a tricopter that performs well in ~25mph but thats because its wide and low profile. usually more motors = more stability in all conditions.
