What you see is water vapor.

The air that you exhale contains water vapor. When you exhale during a cold day, the relative humidity increases. Relative humidity is actually the percentage of the amount of water vapr in the air. (the maximum amount of water vapor that the air can hold at that temperature) The colder the air, the less water vapor it can carry. When exhaled, air mixes with cold air, the temperature of the exhaled air drops, but there is more water vapor. When the air becomes saturated, (relative humidity is 100%), the extra water vapor will condense, allowing you to see your breathe on cold days.

Why can't you see your breath on a warm day?

On a warm day, the air temperature is likely higher than your body temperature, so when you exhale, the warm air quickly mixes with the surrounding air and dissipates. This prevents the condensation of water vapor in your breath, which is what makes it visible on colder days.


When a persons breath forms a cloud on a cold day what is happening?

Your breath contains moisture. On a cold day the warm moisture in your exhaled breath enters the cold air outside your body and forms a "fog" made of small droplets of water.
