Staff If there's a difference between the dew point temperature and the air temperature, then things shift. The body cools by sweating, which then evaporates into the air. Our perception of temperature is affected by humidity levels. National Now let's see how we can use the relative humidity (RH) calculator to find out the relative humidity when the dew point is 70 F and the air temperature is 95 F. 110 and low humidity. I lived in Phoenix and have been in high humidity areas including Florida, Philippines. Comparing conditions at the moment: I When the air is dry, its easy for lawns to dry out after a rainstorm because the water evaporates quickly.
