A dew point measures how much total water there is in the atmosphere. Therefore, it's harder for your body to cool off in the summer by evaporating sweat. So, to sum up: The lower the dew point ...

the relative humidity will quickly drop when the amount of water vapor in the air remains constant. The dew point typically changes much more slowly compared to relative humidity, unless a front ...

After ten days of low humidity, muggy air has returned and will remain for at least the next week (April 18-25) as strong ...
