Why can I see my breath in 60 degree weather?

The water vapor in your breath condenses into a liquid when it hits dew point—the temperature at which the air is saturated and can’t hold any more water in gas form.

Is there less oxygen in cold air?

Cold air is heavier, and thus contains more molecules per volume, of all gases that are in the mix (oxygen stays at 21% by volume). Air at 1atm and 25 degrees Celsius weighs 1.184g per cubic meter, and thus contains 7% less Oxygen than the air at 5 degrees.
