At what point is dew point uncomfortable?
Dew point is a good guide to comfort Most people find dew points of less than 60 degrees comfortable. When the dew point rises above 65 degrees people will begin feeling that the air is “sticky.” As the dew points climb through the 70s the humidity bothers more and more people who are outdoors.
What is the most comfortable dew point?
The optimum combination for human comfort is a dewpoint of about 60 F and a RH of between 50 and 70% (this would put the temperature at about 75 F). The air feels dry outside when BOTH the dewpoint is below 60 F AND the RH is less than 40%.
What dew point is unbearable?
The dew point is the temperature at which the water vapor in the air will condense and the humidity will reach 100%. Dew points below 60°F are comfortable, while those above 65°F are uncomfortable; readings above 70°F are oppressive.
What humidity level is uncomfortable?
