The temperature the air would have to cool to before dew or fog forms. Higher means muggier; above about 65 degrees Fahrenheit feels humid. In technical terms: The temperature to which air must be cooled at constant pressure and water-vapor content to reach saturation with respect to liquid water; a conservative measure of absolute moisture content.
