Does a golf go farther in high humidity or low humidity ?
At the same temperature, the ball travels farther at higher humidity. The difference between 85% and 20% humidity at 85 degrees is only about 1.3 yards for a drive that carries 256 yards (long hitter).
The reason for this is the fact that at higher humidity, there is a greater proportion of water vapour. Water vapour is less dense than the major gases in the atmosphere (Nitrogen, Oxygen) and therefore the air is less dense. Less dense air offers less drag and less lift, the combination which results in slightly more distance.
