How does fog relate to humidity?

Best Answers

IMHO fog is humid air that has cooled below the dew point, so that the humidity (which is gaseous water in air) has condensed into water particles that are suspended in the air. Fog is "liquid humidity.". read more

And they both are directly related to the dew point. The dew point is the temperature at which the air becomes 100% saturated. At that point, the air condenses into water droplets, which we see as fog. The lower the dew point, the drier the air, and vice versa. If you have a temperature of 80 degrees and a dew point of 60, that feels quite humid. read more

The amount of water vapor in the air can dictate what kind of weather we see and how comfortable we are once we step outside. read more
