DEWPOINTTEMPERATURE

WHATISTHE“DEWPOINT”?

Thedewpointisthetemperaturewheremoistureintheaircondensesintowater.Wecommonlyrefertothe

condensedwaterasdew,thereforethetemperatureatwhichthe“dew”formsiscalledthedewpoint.

THERELATIONSHIPBETWEENDEWPOINT,TEMPERATUREANDRELATIVEHUMIDITY

Whenthedewpointisneartothecurrenttemperature,wehaveveryhighhumidity.Ifthedewpointisequaltothe

currenttemp,thatisarelativehumidityof100%.Thismeansthattheairiscompletelysaturatedwithwatervapor.

Whenthedewpointremainsconstantandthetemperatureincreases,relativehumiditywilldecrease.

Astheairtempgoesdown,thedewpointtendstofollow.Alowdewpointcangoalongwithahightemperature

onlyatextremelylowrelativehumidity.

HOWDOESTHEDEWPOINTAFFECTME?



Wetendtobemoreuncomfortableasthedewpointincreases.Asthebody’stemperaturegoesup,webeginto

perspireandproducesweattocooldown.Highhumidity(andthereforeahighdewpoint),willpreventthe

evaporationofsweatandreducesthebody’sabilitytocoolitself,andwefeelhotanduncomfortable.
