How it's calculated
γ = ln(RH/100) + 17.62·T / (243.12 + T); Td = 243.12·γ / (17.62 − γ)
Common questions
What does dew point tell me?
It's the temperature at which the air becomes saturated. Higher dew points mean more moisture in the air — and stickier weather regardless of the thermometer reading.
Dew point vs relative humidity?
RH depends on temperature — the same air feels muggier when it's warm. Dew point is an absolute measure of moisture, which is why meteorologists prefer it.
