Several factors come into play when you are discussing internal combustion
engines.

On the good side we have: low altitude, high barometric pressure, low air
temperature, and LOW humidity content. These are the ideal conditions for an
internal combustion engine to produce power. You want low humidity because
for a given volume of air you want as high a percentage of oxygen as you can
get and not moisture in that given volume. More moisture = less oxygen =
less potential power.
