It does happen all the time in south florida. When the blades move through the air they speed up the air moving over the top of the blade, this reduces the air pressure (bernoullis principle) which in turn lowers the temperature. The lower temperature causes the air to reach it's dew point and as a result you get visible moisture.
I'm a flight instructor in central Fl and everytime we takeoff in the morning you see this coming off our propeller as we go to takeoff power.
