Frequently Asked Questions
What is Dew Point?
Dew Point is the temperature to which air must be cooled for water vapor to condense into liquid water (dew or fog) at constant atmospheric pressure.
Why is Dew Point a better comfort indicator than Relative Humidity?
Relative humidity changes with temperature, while dew point directly measures absolute moisture content in the air (dew points over 65°F / 18°C feel sticky and humid).
