Finding the Dew Point from humidity data

Dew Point is a good indication of whether humans will find an environment uncomfortably hot and sticky. We are most comfortable when the dew point is 10 -18 degrees.

To find the dew point draw a graph of humidity and temperature data and add a line of best fit. Extend this line to the point where it intersects with 100% humidity. The dew point is the temperature measurement at this intersection.
