Required atmospheric conditions to see your breath?

Sure you can see your breath when it is cold, but sometimes you can see it when it isn't so cold, so what are the conditions that require it to be seen?

To be clear, I am not asking why you can see it. Thanks.

    Temperatures below the dew point will do that.

    Warm moist air meets cold if you will.

    It also depends on the relative humidity -- that is, the difference between the air temperature and the dew point.

    "When it falls below 45° F (7.22° C), though, you can usually expect to be able to see your breath."
